Position.MarketPosition

[AnotherTrader]

 
If(mySignal && Position.MarketPosition == MarketPosition.flat)
                EnterLong();

I have two strategies running in Sim on the same instrument.
These two strategies differ only in exit conditions; entry conditions are identical, and so they should both enter at the same time.
But only one is entering; the other does not.
Is this because the above condition is checking overall position for the instrument across all strategies, rather than just the position for the instrument under each strategy separately? So strategy A enters, and then strategy B sees account already has a position in the instrument, and so fails to enter?

Hello AnotherTrader,
Position.MarketPosition check for the current market position of the strategy only and not the overall market position.

Say you are long in both strategy A and strategy B. Now say an exit is triggered in strategy A and so strategy A is not flat. Sometimes later an entry is triggered by the strategy. You will witness an entry order being submitted by strategy A, but strategy B will not submit any order since it is already in a position and internal order handling rules will reject any position in the same direction unless Entries per direction is defined accordingly.

Further your code filters the entry orders as:
If(mySignal && Position.MarketPosition == MarketPosition.flat)
EnterLong()

Since you are not flat in strategy B will ignore the entry orders.

Please let me know if I can assist you any further.
