0. This test should run in sim market with merged turned on

ExchangeSim {value {merge_with_md:true}}

1. Bring up a market view for SI futures. There are 3 quantity columns
a. Implied : This is the quantity coming purely from implieds (ex for the spreads, this is 
'implied' from the legs)
b. Direct : This comes purely from markets in the security itself
c. Qty (or Merged Qty) == Implied + Direct.

2. Select a future with only implied markets (SI should have lots of them). Verify that the ladder
agrees with the market view (the ladder shows merged by default).


3. Enter buy and sell orders away from the market and make sure they show up as direct market in the ladder.

4. In the ladder settings -> Market Data, select Direct Only. Make sure the ladder does the right thing.

5. Go back to Merged and make sure the Ladder does the right thing.

6. Make you direct bid better than the implied bid (by moving your buy order) and make sure MView does the right thing.

7. Repeat 6 for sell/ask.
