+# C#/.NET
+
+We target [.NET Standard 2.0](https://docs.microsoft.com/en-us/dotnet/standard/net-standard) so you can use .NET Framework 4.6.1+ or .NET Core 2.0+.  Simply add a reference to the [Spark Nuget package](https://www.nuget.org/packages/spark_sdk/) to get started.
+
+```
+dotnet new console -lang c#
+dotnet add package spark_sdk
+dotnet build
+```
+
+# C++
+
+The easiest way to get started with C++ is to use the Spark Server SDK to develop your application.  Follow the instructions to [download and install the Spark Server SDK](/server/getting-started/install) and open the client_sdk sample project. If you want to run your C++ Client SDK application on Windows [contact us](mailto://api@bluetradesys.com) to get the required headers and binaries.
+
+# JavaScript
+
+We use JavaScript internally with the Spark Client API over a websocket connection but the documentation and packaging isn't ready yet.  If this is something you're interested in get in touch with us at [api@bluetradesys.com](mailto:api@bluetradesys.com).

+
+The Spark Client SDK is a high level command and control API which can be used to build scripts or integrate Spark into your existing ecosystem.  The API is divided into several independent **"services"** responsible for different aspects of the system.  A Service can define both [remote procedure call (RPC)](/client/getting-started/services#rpc) and incremental [streaming](/client/getting-started/services#streams) data.
+
+The [Spark Desktop](https://www.bluetradingsystems.com/bts-spark/) is built on top of this API so you can be assured that it is complete and well tested.
+
+Spark uses [Google Protocol Buffers](https://developers.google.com/protocol-buffers/) as an interface definition language similar to [GRPC](https://grpc.io) but backed by our custom high-performance TCP protocol.  We currently support C#/.NET and C++ <!--and Javascript--> but the architecture is designed for easy extension so contact us about your specific business needs.
+
+## Orders
+
+Use the [OrderService](/client/services/orderservice) to send and manage orders including native exchange orders, spreader orders, and custom Algo orders created using the [Spark Server SDK](https://api.bluetradesys.com/server/).
+
+## Spreader
+
+Use the [SyntheticSecurityService](/client/services/syntheticsecurityservice) to create and manage synthetic spreads.  Once created these spreads show up in the security and market data feeds just like exchange listed spreads.
+
+## Position
+
+Use the [PositionService](/client/services/positionservice) to get your position and P&L reports or add fills manually to keep the Spark system up to date with an external system.
+
+## Administration
+
+Use the [AdminService](/client/services/adminservice) to manage users and control limits.
+
+## Market Data
+
+For .NET subscribe to market data though the high level MarketDataClient interface.  From C++ or JavaScript use the MarketDataRelay service directly.

+
+The Spark Client SDK uses [Google Protocol Buffers](https://developers.google.com/protocol-buffers/) to define the interface for each service in a language independent manner.  Services have both functions which return a single result and streams of data which return values continuously while subscribed.  This page describes the mapping from the Protocol Buffer definition to the concrete definition in each supported language.
+
+# ServiceContext
+
+To connect your client to the Spark Server you need to get or create a `ServiceContext` instance.  A `ServiceContext` represents a connection to the Spark Server and a background thread for handling messages on that connection.  Generally there should be a single `ServiceContext` per process.  All of the methods on the `ServiceContext` are safe thread safe.
+
+Construct a ServiceContext by calling the default constructor.  The ServiceContext will find the Spark Server by loading the server configuration over an HTTP connection.  To determine the URL it will search the following locations and use the first one that is present.  
+
+* A command line argument `-configserver <url>`
+* An environment variable `BTSCONFIG`
+* `%APPDATA%/bts/conf/spark.conf` (Windows)
+* /sparkdata/conf/spark.conf (Linux)
+* $HOME/sparkdata/conf/spark.conf (Linux)
+
+If your application is running on a system with the BTS Client installed this will probably work without any further configuration.  If you plan to run your client application on a separate machine we recommend setting the `BTSCONFIG` environment variable.
+
+<div class="info">
+<i class="fa fa-lightbulb-o fa-fw" aria-hidden="true"></i>
+If you are using the Spark Server SDK to run a local copy of the Spark server set <p><strong>BTSCONFIG = http://localhost:9000/config/</strong></p>
+</div>
+
+To get a proxy for a given service call ServiceContext.locate&lt;T>("qualifier") where T is the type of the service and "qualifier" is an optional qualifier used to disambiguate between 2 instances of the same service.  The locate call cannot fail but it may return a disconnected proxy.  When you make a call on the proxy you should check the call result to see if the method call succeeded.
+
+# RPC
+
+Here is the OrderService reduced to a single method definition. A RPC method always takes exactly 1 argument and returns 1 value.  In this example the `create_order` call takes a `Create` instance and returns a `Response`.  
+
+```C
+service OrderService { 
+  rpc create_order(Create) returns (Response);
+  ...
+}
+```
+
+The `Create` and `Response` types are also defined as protocol buffer messages.  Each field can either be a primitive type another message or a list or map.
+
+```C
+message Create {
+  OrderDefinition new_order = 1;
+  double price = 2;
+  uint32 quantity = 3;
+}
+
+message Response {
+    uint32 order_key = 1; 
+    OrderError error_code = 2; 
+    string msg = 3;
+}
+```
+
+Each RPC call generates both synchronous (blocking) and asynchronous variants. In C# the asynchronous calls have the `_async` suffix and return a `Task`.  In C++ the call is overloaded to either return a value synchronously or accept a callback function to be called on the ServiceContext thread when the call completes. <!-- In Javascript only async methods returning a Promise are generated because it never makes sense to make a blocking call in the browser. -->
+
+To call the resulting service locate a proxy using the [ServiceContext](#servicecontext) and then call `cancel_order` or `cancel_order_async`.  If you are calling the Spark API from a GUI application you should always prefer the `_async` version of the calls.
+
+
+### C# example
+```c#
+var ctx = new ServiceContext();
+var orders = ctx.locate<OrderService>();
+var response = 
+  await orders.create_order_async(
+    new Create { price = 2.25, quantity = 42 });
+if (response.success) {
+  Console.WriteLine($"success: {response.value}");
+}
+else {
+  Console.WriteLine($"Error: {response.error_message}");
+}
+```
+### C++ example
+```cpp
+auto ctx = ServiceContext{};
+auto orders = ctx.locate<OrderService>();
+Create c;
+c.set_price(2.25);
+c.set_quantity(42);
+// Instead of providing an _async method C++ uses overloading.
+// To make a syncronous call simply omit the callback
+orders.create_order(c, [=](const Result<Response>& response) {
+  if(response.success()) {
+    std::cout << "success.";
+  }
+  else {
+    std::cout << "error: " << response.error_message();
+  }
+});
+```
+
+# Streams
+
+Streams allow you to subscribe to live updating data. Each stream represents a changing collection of protocol buffer objects.  Similar to a database row each item has an `id` which uniquely identifies it within the collection.  Updates from the Spark server can add, remove or replace entries in the collection.  Since only the changed items are sent over the wire the stream can remain responsive even when it represents a large collection.
+
+Streams are implemented using the language bindings for [ReativeX](http://reactivex.io/) which provide utility functions to drill down to the specific data your application needs. In C# we provide both mutable and immutable versions of the generated data types (C++ users can rely on `const`).
+
+When defined in a proto file streams use the `stream` keyword on the result type.
+```C
+service OrderService { 
+  ...
+  rpc fills (FillsSub) returns (stream Fill);
+}
+```
+
+### C# example
+```c#
+  var sc = new ServiceContext();
+  var orders = sc.locate<OrderService>();
+  var fills_observable = orders.subscribei_fills();
+  var unsub = fills_observable.Subscribe(update => {
+    Console.WriteLine(
+        "Added {0} items, Removed {1} items, Updated {2} items.  Total items {3}", 
+        update.added.Count(), 
+        update.removed.Count(), 
+        update.changes.Count(), 
+        update.all.Count());
+  });
+
+  Thread.Sleep(TimeSpan.FromMinutes(5));
+  unsub.Dispose();
+```
+### C++ Example
+```cpp
+#include "lib/api/public/ServiceContext.h"
+#include "lib/api/services/OrderService.client.pb.h"
+using namespace bts::api;
+ServiceContext ctx;
+auto orders = ctx.locate<orderman::OrderService>();

+    << "Total items " << update.all().size() << std::endl;

+In this section we're going to use the Remote - Containers feature of <a href="https://code.visualstudio.com/" target="_blank">Visual Studio Code<i class="fa fa-fw fa-window-restore" aria-hidden="true"></i></a> to simplify the development experience. If you are using a different editor skip to the <a href="#other-editors">other editor</a> section below.
+
+## Remote - Containers
+
+The Visual Studio Code Remote containers extension allows it to run a complete development environment inside the Spark SDK Docker container.  The editor UI runs as a thin client on your desktop and connects to a headless instance running inside the Spark SDK Docker environment.  This configuration allows us to ship a pre-configured set of [Tasks](https://code.visualstudio.com/Docs/editor/tasks) for building and testing your code.
+
+Start Visual Studio Code and click on the puzzle piece icon on the left-hand side to open the extensions panel. Use the search box at the top to find the "Remote - Containers" extension and install it.
+
+<img src="../vscode_remote_containers.png" width="640" />
+
+## Into the Code
+
+Open the examples/algo_template directory using the File->Open Folder menu option. If you opted to add it to your path during install, you could run `code .` from your command prompt.
+
+When the workspace opens, you should see a notification offering to let you re-open the workspace inside the container.
+
+<img src="../vscode_notification.png" width="480" />
+
+The first time you open the workspace inside the container it will take a few seconds to configure the spark_sdk docker container.  While the workspace is open in Visual Studio Code the docker image will also be running in the background.  The container will stop automatically when you close the editor.
+
+Open algo_template.cpp from the file browser on the left or by pressing ctrl-p and typing the name.  Each Algo is a standard C++ class which implements **IAlgoOrder**.  Placing your cursor on IAlgoOrder and pressing F12 will take you to the IAlgoOrder.h header file where you can browse the API.  To learn more about how an Algo is instantiated see the [Algo Initialization](/server/ref/initialization).
+
+## Compiling
+
+To build press "Ctrl+Shift+B".  You should see the build output at the bottom of your screen.  If the build was successful the resulting algo_template.so will be automatically copied to the plugins directory where it will be loaded by the Spark server process on start.
+
+<img src="../compiled.png" width="640" />
+
+## Debugging
+
+To debug your Algo set a breakpoint (F9) and open the Debug panel (Ctrl+Shift+D) and choose "(gdb) Launch".  This will launch the Spark Server inside the container with the debugger attached.  
+
+<img src="../gdb_launch.png" width="380" />
+
+With sparkd running you can launch the Spark Client (spark_client.cmd) and it will connect to the running server.  Log in with the user "bts" and no password and open a ladder.  You can now select your Algo on the order type dropdown and activate it by clicking on a price on the ladder.
+
+<img src="../myalgo.png" width="150" />
+
+While sparkd is running you can also access the Spark Server Admin interface on [http://localhost:9000](http://localhost:9000).  Use the same "bts" login to access the admin interface. Here you can manage user and account permissions and risk limits.
+
+## Starting Spark Server
+
+To start the Spark Server without attaching a debugger press "Ctrl+Shift+P" and select "Tasks: Run Task" and then "Start Sparkd" and "Never scan task output"  This will open a new terminal where you can see any messages logged with the **Sdk** subsystem as well as any warnings or errors.  To stop the Spark server simply kill the terminal (trash can icon) or run the "Stop Sparkd" task.

+# Other Editors
+
+In this section you will be more exposed to the details of how Docker works and how to compile and test your Algo using the command line. 
+
+## Docker
+
+Spark Server is built and runs only on Linux so you need a Linux development environment to effectively develop plug-ins for it. Docker lets you take the spark_sdk.img disk image and run it inside a virtual Linux machine running on your Windows desktop. 
+
+First, some terminology.  A Docker "image" is a disk image containing a complete filesystem. The spark_sdk.img file you imported earlier is an image.  A Docker "container" is what you get when you get when you attach this image to a running Linux system.  You can connect to a running container and use it to run commands like the C++ compiler or the Spark server.  Directories from your local filesystem can be mapped into the Docker container when it starts so you can easily share files.
+
+### Start
+
+The first step is to start the spark_sdk Docker container with the examples directory mapped so we can compile the examples inside the container. In your command prompt cd to the *examples* directory that you unzipped from the spark_sdk.zip file.  Then run the following command to start the container.
+
+Windows Command Prompt:
+{% clipable() %}
+docker run --rm -it -v %CD%:/examples -u bts -w /examples --shm-size 2048m --name spark_sdk -h spark_sdk --cap-add=SYS_PTRACE --security-opt seccomp=unconfined -p 9000:9000 -p 9001:9001 spark_sdk bash
+{% end %}
+
+**Powershell** / Linux / Mac:
+{% clipable() %}
+docker run --rm -it -v ${PWD}:/examples -u bts -w /examples --shm-size 2048m --name spark_sdk -h spark_sdk --cap-add=SYS_PTRACE --security-opt seccomp=unconfined -p 9000:9000 -p 9001:9001 spark_sdk bash
+{% end %}
+
+### Attach
+
+The container will remain as long as this prompt is open.  You can attach an additional to the running container with the following command:
+{% clipable() %}
+docker exec -it spark_sdk bash
+{% end %}
+
+## Compiling
+
+Let's look at the algo_template sample first.  All of the samples are laid out similarly with a `build.sh` script for compiling.  As long as you are running build.sh inside the spark Docker container, it automatically copies the build output to /sparkbin/plugins/ where it needs to be to get loaded by the Spark server.
+
+```
+bts@spark_sdk:/examples$ cd algo_template/
+bts@spark_sdk:/examples/algo_template$ ./build.sh
+algo_template.so copied to /sparkbin/plugins/
+Restart sparkd to see changes.
+```
+
+## Starting Spark Server
+
+To start the Spark server `cd /sparkbin/` and run `./sparkd run`.  Press Ctrl+C to stop it.
+```
+bts@spark_sdk:/sparkbin$ ./sparkd run
+2019-10-25 16:21:09.383626|262552152803600|Gen|Warn |1  |main|132 |Run.cpp:53 |dev|
+------------------------------------ Sparkd launched --------------------------------
+```
+
+You will see any Sdk log messages as well as any log messages at or above Warning level from other parts of the system.  If you need additional diagnostic information more details logs are stored in /sparkdata/data/logging/log.  These logs will be automatically deleted when you stop the Docker container.
+
+With sparkd running you can launch the Spark Client (spark_client.cmd) and it will connect to the running server.  Log in with the user "bts" and no password and open a ladder.  You can now select your Algo on the order type dropdown and activate it by clicking on a price on the ladder.
+
+<img src="../myalgo.png" width="150" />
+
+While sparkd is running you can also access the Spark Server Admin interface on [http://localhost:9000](http://localhost:9000).  Use the same "bts" login to access the admin interface. Here you can manage user and account permissions and risk limits.
+
+## Debugging
+
+You can debug your algo using gdb from the bash command prompt.  
+
+```bts@spark_sdk:/sparkbin$ gdb --args ./sparkd run
+GNU gdb (Ubuntu 8.1-0ubuntu3) 8.1.0.20180409-git
+Copyright (C) 2018 Free Software Foundation, Inc.
+...
+Reading symbols from ./sparkd...done.
+(gdb) break algo_template.cpp:45
+No source file named algo_template.cpp.
+Make breakpoint pending on future shared library load? (y or [n]) y
+Breakpoint 1 (algo_template.cpp:45) pending.
+(gdb) run
+Starting program: /sparkbin/sparkd run
+```
+
+If your editor supports debugging over the ssh protocol you can start sshd from inside the container.

+## Request Access 🔑
+
+To start using the Server SDK you will need to request access though our sales department.  Please email <a href="mailto:api@bluetradesys.com">api@bluetradesys.com</a> or call <a href="tel:919-913-0850">(919) 913-0850</a> and we will provide download credentials.
+
+## Download
+
+Download the latest SDK image here: [spark_sdk.zip](https://api.bluetradesys.com/download/spark_sdk.zip)
+
+Unzip that folder into a working directory. Inside you should see something like this:
+
+```
+spark_sdk.img
+client/
+spark_client.cmd

+```
+
+## Import

+
+## Update
+
+To update your Spark SDK simply download an unzip a new [spark_sdk.zip](https://api.bluetradesys.com/download/spark_sdk.zip) and use `docker load < spark_sdk.img` to overwrite the old image with the new one.
+
+To preserve the old image so you can go back to it later run `docker tag spark_sdk spark_sdk:your_custom_tag` before loading the new SDK image.
+
+### Re-build the Dev Container
+
+If you are using Visual Studio Code you also need to rebuild the dev-container so it picks up the new image.
+
+#### Inside VSCode
+To re-build from inside Visual Studio Code.  Click the 'Remote Explorer' icon on the left hand side. 
+You should see your spark_sdk project listed under the Containers section.  Right click on it and select **rebuild-container**.

+The minimum hardware requirements for using the SDK are:
+- **12 GB** RAM (preferably 16 GB or more)
+- 4 CPU cores
+- 20 GB free hard disk space
+
+The Spark SDK uses a tool called Docker to distribute all of the tools you need to build and test your trading algorithm ("Algo").  Once you have Docker installed you can download and import the Spark SDK image and be ready to start developing your Algo in a few minutes. 
+
+## Docker
+
+Download and install <a href="https://www.docker.com/products/docker-desktop" target="_blank">Docker Desktop for Windows/Mac. <i class="fa fa-fw fa-window-restore" aria-hidden="true"></i></a>
+

+If you are using Linux follow the <a href="https://docs.docker.com/install/#supported-platforms">official install instructions for Docker for your distribution.</a>
+</div>
+
+During the install Docker may ask you to enable virtualization support and reboot.
+
+Once Docker Desktop is installed and running it will create an icon in your system tray area that looks like the Docker logo.  
+![](../docker_tray.png)
+
+Right click on the tray icon and choose 'Settings' and choose the 'Advanced' tab.
+
+Ensure that the docker image has 8192 MB of memory and at least 2 cores.  Memory that you assign to the docker image will not be available to Windows/Mac while Docker is running. CPU cores are shared with the host OS.  Since you are going to use this image to compile your Algo it makes sense to allow Docker to use all available cores.
+
+<img src="../docker_config.png" width="640" >

+
+Using the **Spark Server SDK**, users can create new order types ("Algos"). In this case, users implement the new functionality in C++, producing a shared library that is loaded at run time by our Spark Server.
+
+If you are interested in accessing Spark server remotely, please see the [Spark Client SDK](/client/).
+
+## Speed
+
+The Spark platform offers a sub-10 microsecond socket to socket response times for algorithmic trading.  With the **Spark Server SDK**, you can create your order types in high-performance C++ and load them into the Spark server. 
+
+Since your order is running inside the Spark Server, there is virtually no overhead allowing your algorithm to take full advantage of the speed Spark offers. Hosting a high-performance language like C++ directly in the Spark server process allows it to respond to the market thousands of times faster than an Algo built using a proprietary drag and drop tool.
+
+
+## Easy to Get Started
+
+If you are not actively developing with C++, it can be time-consuming to set up a complete development environment from scratch.  That is why we provide a full development environment out of the box with [Docker](https://docker.io) so you can download and try the Server SDK quickly and easily. 
+
+Docker works across Windows, macOS, and Linux, so you don't need to change your development environment to try the Spark API. Docker also ensures that all of the dependencies you need are packaged together in one image, so you know it will work out of the box, no matter the platform.
+
+## Implementation
+
+Creating a new Algo begins with implementing a standard C++ class derived from IAlgoOrder. Start from the [algo_template](/server/samples/template) example to get going quickly.
+
+The first call your new Algo receives is [do_before_launch](/server/ref/initialization#before-launch), which is an opportunity to validate parameters and allocate any long-lived resources needed during execution.  Next, it receives either [do_launch](/server/ref/initialization#launch-launch-attached) in the case of a new order or [do_launch_attached](/server/ref/initialization#launch-launch-attached) if the order is attaching to an existing order.
+
+The Algo receives a reference to [IAlgoServices](/server/ref/subscriptions/), which is how it calls out to the Spark system.  It will use [IAlgoServices](/server/ref/subscriptions/) to subscribe to market events, launch and control child orders, and communicate its state to the larger Spark system.
+
+## Fully Integrated
+
+When a Spark Server plugin is loaded, it registers its exposed Algos with the Spark Server though the [init_spark_plugin](/server/ref/registration) callback.  This callback allows the Algo to describe the parameters it expects so they can be automatically entered in the [Spark Client](https://www.bluetradingsystems.com/bts-spark/).
+
+<img src="../myalgo.png" width="150" />
+<img src="../paramsui.png" width="460" />
+
+Compose your Algo with out of the box Algos in the [Spark Algo Studio](https://www.bluetradingsystems.com/news/155-bts-algo-studio-provides-algo-library-with-customization-functionality) to create new functionality on the fly.

+
+## I don't see the header files in the .zip file. Where are they?

+The SDK headers are baked into the docker image along with the build tools.

We still recommend doing the actual build inside the docker environment but having a copy of the headers can be useful for setting up your development environment.

+Each Algo derives from IAlgoOrder and overrides virtual methods to receive callbacks from the Spark system.
+
+
+## Before Launch
+
+When an order is activated by a user or by another Algo, the first call it receives is do_before_launch.  This call happens outside of the latency-sensitive path, so it's the place to validate parameters and set up data structures that the Algo might need.
+
+This call returns an OrderOpResult, which allows it to fail and return an error message to its creator.  If a user created this order, this message is displayed in the [Activity Log](https://www.bluetradingsystems.com/docs/bts_spark/Help/#activity-log) and across the bottom of the ladder.
+
+Every SDK Algo is a "Dynamic" Algo since it's parameters are defined during [registration](/server/ref/registration/). Use the `get_if<T>` helper to retrieve a named parameter from the `order_params` collection as a `std::option<T>`.  If a parameter has a valid default value you can use `std::option::value_or(...)` to set default values for missing parameters.  If a parameter *must* exist or must be within a certain valid range, return an error to the caller.
+
+```cpp
+OrderOpResult MyAlgo::do_before_launch(IBeforeLaunchAlgoServices& serv) {
+   auto& def = serv.definition();
+   auto& params = def.custom_def().dynamic().order_params();
+   auto mqi = get_if<uint32_t>(params, "Min Quantity");
+   if (!mqi || mqi.value() == 0)
+      return OrderOpResult{
+          ORDER_ERROR_INVALID_ORDER_DEFINITON,
+          "Min Quantity parameter must be defined and non zero"};
+}
+```

+</div>
+
+### IBeforeLaunchAlgoServices
+
+IBeforeLaunchAlgoServices is passed to `do_before_launch` and allows the Algo to query its environment.
+
+```cpp
+class IBeforeLaunchAlgoServices {
+ public:
+   // The OrderDefinition for this algo
+   virtual api::orderman::OrderDefinition const &definition() const = 0;
+
+   // The security this algo is paramterized with (also available from
+   // definition())
+   virtual api::Security const &security() const = 0;
+
+   // The unique order key for this algo
+   virtual OrderKey order_key() const = 0;
+
+   // The parent key for this algo's parent or null_order_key() if the
+   // algo does not have a parent
+   virtual OrderKey parent_order_key() const = 0;
+
+   // The security identified by k or nullptr if no such security exists
+   virtual api::Security const *lookup_security(SecurityKey k) const = 0;
+
+   // Wheter this algo is being attached to an existing order.
+   // If an algo does not support attaching it can return an error 
+   // if is_attaching() == true from do_before_launch.
+   virtual bool is_attaching() const = 0;
+
+   // Build a child template that can later can be used to quickly
+   // launch child orders. The reserve parameter indicates how many
+   // orders should be created ahead of time, before they are
+   // launched. This is usefull to remove the relatively expensive
+   // order creation operation to a background thread.
+   virtual ChildTemplate &
+   make_child_template(api::orderman::OrderDefinition const &child_def,
+                       size_t reserve = 1) = 0;
+
+   // Get the current time
+   virtual TimeStamp get_time() const;
+};
+```
+
+
+## Launch / Launch Attached
+
+Depending on the state of `is_attaching()` the next call will either be `do_launch` or `do_launch_attached`.  The only difference is that in `do_launch_attached` the existing OrderKey and ChildState are provided.
+
+`do_launch` and `do_launch_attached` are in the latency-sensitive path and should not do more work than needed.  These functions get a reference to `IAlgoServices`, which is a superset of the functionality available on `IBeforeLaunchAlgoServices`.  Most Algos should store a pointer or reference to this object for managing child orders (it has a stable address).
+
+Now is the time to use `IAlgoServices` to subscribe to market events that are relevant to your Algo and create any child orders that need to exist at the start of your Algo. You can safely call IAlgoServices from any `IAlgoOrder` callback.
+
+To learn more about subscribing to events see [subscriptions](/server/ref/subscriptions).
+
+### Things to do in the launch callback
+☑ Store a reference to IAlgoServices  
+☑ Subscribe to relevant market events  
+☑ Launch a child order?
+
+
+## Update
+
+If the user or parent Algo changes the order parameters (price, size, or the custom parameters defined during registration), Spark calls the `do_update` callback with the new parameters.  It is up to the Algo to decide how to apply the new parameters to update the running state.  It can do this by canceling, changing, or adding new child orders.

+
+Every Algo must, at some point, launch a child order to be useful. Each child order can be another Algo or regular exchange order.  When the child order is updated or filled, those changes are also sent to the parent.
+
+
+# Templates
+
+Since launching a child order is one of the most latency-sensitive things an Algo can do, the Server SDK enables you to create a child template.  An order template prepares an order based on a known OrderDefinition and gets it ready to send on a background thread.  When the Algo determines it is time to send the order, it only needs to provide the price and quantity to complete and send the order.  If an Algo expects to send multiple child orders, it can reserve more than one.  Preparing a child template is typically done in [do_before_launch](http://127.0.0.1:1111/server/ref/initialization/#before-launch) callback.
+
+```cpp
+virtual ChildTemplate& 
+    IBeforeLaunchAlgoServices::make_child_template(
+        api::orderman::OrderDefinition const &child_def,
+        size_t reserve = 1);
+```
+
+# Launch
+
+IAlgoServices provides two overloads for launching child orders.  By default, launching a child order automatically subscribes the Algo to its state changes.
+
+Launch a child order from a template if you have one prepared. This is the fastest option.
+```cpp
+OrderKey IAlgoServices::launch_child(ChildTemplate&, Price, Quantity, bool subscribe = true);
+```
+Launch a child order by constructing an OrderDefinition as needed.
+```cpp
+OrderKey launch_child(OrderDefinition const &, Price, Quantity, bool subscribe = true);
+```
+
+When a child is launched its `OrderKey` is returned to the caller.  This ID can be used to update, cancel, or detach the child order.

+To update an existing child order, call update_child and pass an Update.  The Update type lets you change the price, size or the entire OrderDefinition. You only need to specify the fields that you intend to update so only set the price() field if that is what you are changing.
+
+```cpp
+void IAlgoServices::update_child(OrderKey child, api::orderman::Update const &);
+```
+
+## Cancel
+
+To cancel an existing child order call `cancel_child`.  When the order is canceled you will receive an update though the `on_child_change` callback.
+
+```cpp
+void IAlgoServices::cancel_child(OrderKey child);
+```
+
+## Detach
+
+The lifetime of a child order is tied to its parent.  If a parent is canceled or completed child orders are automatically stopped as well.  If the Algo needs to launch an order that will continue after the Algo ends use `detach_child` to sever the connection.  This order hierarchy can be viewed in the Spark [Order Book](https://www.bluetradingsystems.com/docs/bts_spark/Trading/#order-book).
+
+```cpp
+void IAlgoServices::detach_child(OrderKey child);
+```
+To detach all children at once use `detach_all_children`.
+
+```cpp
+void IAlgoServices::detach_all_children();
+```
+
+# Child Updated
+
+When a child order is updated the parent receives the `on_child_change` callback with an updated ChildState object.
+
+```cpp
+void on_child_change(OrderKey, ChildState const &) override;
+
+struct ChildState {
+   Price price;
+   Quantity quantity;
+   Quantity total_fills;
+   Price avg_price;
+   Quantity last_fills;
+   Price last_price;
+   ChildStatus status;
+   Quantity fills_at_attach_time;
+};
+```

+
+When Spark Server starts, it loads all plugins listed in the /sparkbin/plugins directory and calls an exported function named `init_spark_plugin` which must have the following signature.
+
+```cpp
+extern "C" void init_spark_plugin(bts::SparkServices &serv) { }
+```
+
+The `init_spark_plugin` function registers the Algo with a DynamicOrderDescriptor. Once registered, the Algo appears in the [Spark ladder](https://www.bluetradingsystems.com/docs/bts_spark/Trading/#ladder) and the [Algo Studio](https://www.bluetradingsystems.com/docs/bts_spark/Trading/#algo-studio).
+
+To register an Algo call `register_dynamic_algo_order` on the provided bts::SparkServices instance. This function takes the DynamicOrderDescriptor and a function that is called to construct the IAlgoOrder. A single init_spark_plugin can call register_dynamic_algo_order multiple times to register multiple Algos.
+
+The DynamicOrderDescriptor must have a dynamic_order_type (name), or the registration will fail.
+
+```cpp
+   DynamicOrderDescriptor desc;
+   desc.set_dynamic_order_type("My Algo");
+   auto result = 
+      serv.register_dynamic_algo_order(
+       desc, []() { return std::make_unique<MyAlgo>(); });
+   if (result != bts::AlgoRegistrationResult::SUCCESS) {
+       // Algo failed to register
+   }
+```
+
+
+## DynamicOrderDescriptor
+
+The DynamicOrderDescriptor describes the type of parameters that the Algo accepts.  These inputs can come either from the user manually entering them or from a parent Algo.  Spark Algos are composable, so one Algo can activate another.  See [Child Orders](/server/ref/orders) for more on how to activate custom order types as child orders.
+
+Add parameters to the DynamicOrderDescriptor by calling `add_param_desc()` and setting the name and parameter type.
+
+```cpp
+   *desc.add_param_desc() = param_bool("Enable Feature");
+   *desc.add_param_desc() = param_uint32("Feature Quantity");
+```
+
+The above parameters look like this when rendered in the Spark ladder.
+
+<img src="../paramsui.png" width="460" />
+
+And like this when viewed in the Spark order book.
+
+<img src="../orderbook_truncated.png" width="988" />
+
+Each descriptor can be one of the following types:
+```
+// Primitive
+int32
+uint32
+double
+string
+bool
+// Complex
+Order
+Array
+Struct
+```
+
+**Currently the Spark UI only renders parameters with primitive types.**  The complex types can only be provided by a parent order.
+
+### Order
+
+This parameter type indicates that another order type parameterizes this Algo. When the Algo needs to create a child order, it can use this parameter type to create a custom order type instead of defaulting to a limit order.
+
+For example, an Algo might be designed to wait for a specific market condition before putting in an order.  Instead of placing a limit order when the condition is met, the user can specify that it should an IceBerg order.  The Algo doesn't need special logic to handle different child order types.
+
+### Array
+
+An array parameter is a collection of the same type of parameter.  If your Algo needed to behave differently depending on a table of prices, you could send that list in though an array parameter.
+```cpp
+    *desc.add_param_desc() = 
+        param_array("Price Points", 
+            param_double("unused").param_type());
+```
+
+### Struct
+
+A struct parameter is a set of named parameter types similar to the entire DynamicOrderDescriptor.  The struct parameter type can be combined with the array type to handle tabular data.
+
+```cpp
+    *desc.add_param_desc() = 
+        param_array("Step Table", 
+            param_struct("", {
+                param_uint32("Market Quantity"),
+                param_uint32("Order Quantity")
+            }).param_type());
+```

+
+An Algo exists to observe changes in the market and respond to them. When the Algo is [launched](1/server/ref/initialization/#launch-launch-attached) it uses IAlgoServices to subscribe to the events it needs to operate.  Each subscribe call is paired with a matching unsubscribe call, which takes the same argument to unsubscribe.
+
+# Book
+
+Subscribe to book updates for the specified security call use subscribe_book and unsubscribe book.
+```cpp
+// Subscribe to book updates for the specified security
+void IAlgoServices::subscribe_book(SecurityKey);
+void IAlgoServices::unsubscribe_book(SecurityKey);
+
+// You implement
+virtual void on_book(SecurityKey, Book const &) override;
+```
+Get the `SecurityKey` of the current security using:
+```cpp
+services.subscribe_book(SecurityKey(algo_services().security().id()));
+```
+If your Algo needs to subscribe to other securities, their keys must be passed in as parameters.
+
+
+To get the details of a security use
+```cpp
+api::Security const* IBeforeLaunchAlgoServices::lookup_security(SecurityKey k) const = 0;
+```
+
+# Timer
+To handle time-based logic, an Algo can subscribe to a common timer event that is invoked once every 10 milliseconds.  Use the TimeStamp class from `bts_chrono.h` to efficiently handle time calculations.
+```cpp
+// Subscribe to a periodic 10ms timer
+void IAlgoServices::subscribe_timer();
+// You implement
+virtual void on_timer() override;
+```
+
+# Ticker
+The status callback is called when the market for this security opens, closes, or has some other state transition.
+```cpp
+// Subscribe to trade ticker
+void IAlgoServices::subscribe_ticker(SecurityKey);
+// You implement
+void on_ticker(SecurityKey, TradeVector const&) override;
+```
+
+# Trading Status
+
+The status callback is called when the market for this security opens, closes, or has some other state transition.
+```cpp
+// Subscribe to security trading status
+void IAlgoServices::subscribe_status(SecurityKey);
+// You implement
+virtual void on_status(SecurityKey, co2::TradingStatus) override;
+```
+
+# Child Orders
+
+When an Algo launches a child order, it is subscribed to the changes on that child automatically.  If the Algo unsubscribes from those changes, it can re-subscribe using this method.
+
+```cpp
+// Subscribe to child order updates for the specified child order.
+void IAlgoServices::subscribe_child_change(OrderKey);
+// You implement
+virtual void on_child_change(OrderKey, ChildState const &) override;
+```
