Checking that Position is Flat

[huracan]

I have a strategy that calls an ATM Strategy. The ATM Strategy starts with 4 contracts and scalps 3 at 4 ticks, then lets the last one run with a trail stop. In the strategy code I need to ensure that the last contract has closed before setting up another trade (order). I'm using this:
if( GetAtmStrategyMarketPosition(ATMOrder) == MarketPosition.Flat) {
// ATM is done - can allow a new order
Print("Order Complete");
}

Instead, "Order Complete", prints out after the first 3 contracts are scalped. Am I using the correct approach here?

Thanks.

How are you determining that it has not closed the 4th already as well? What does GetAtmStrategyPositionQuantity() say?

Josh:

I will add that check. Here's how I determined there was an issue: I had the DOM running and the Output Window visible concurrently. I saw the ATM strategy begin, the order fill and the first target hit. So, I was left with a contract that was being trailed. That last contract took enough time that I could look at Output Window and see the "Output Complete" print, before the
trailing stop hit it much later.

Having said all that, I'll add the check you suggest and see what results.

Thanks.
