How to make a ban on opening?

[turalex]

Writing strategy through StrategyWizard.
Put a simple condition - Long more EMA and shorts less EMA and close by TrailStop.
But the position is closed not only to TrailStop, but when performed opposite condition - if have open Long and fulfillment of the terms "less EMA" - Long then close and open shorts.
How to do that would not open until closed by TrailStop?

Hi turalex,

If you want to ensure that the order has been exited before placing a new order, check that the market position is flat.

Add a condition to each condition set.
On the left of the condition builder select Strategy -> Market Position.
On the right side of the condition builder select Strategy -> Flat.
This should make a condition:
Position.MarketPosition == MarketPosition.Flat in the condition set.
