Delay between Executions to Prevent Duplicate Positions

[rezamerik]

Is there a command in NinjaScript to introduce a brief delay, say 1 second, between trade executions? I've created a simple MA-Crossover strategy where the goal is to flatten and reverse the position when the crossover happens. The problem is sometimes instead of one contract, two are opened! I'm considering adding a slight delay between the stop-out and opening a new position in the opposite direction to resolve this. If you have a better solution, I'd appreciate your assistance. Thanks!

Hello rezamerik,

Thank you for your post.

Are you calling an exit at the same time as an entry? Calling an exit followed immediately by an entry will double the quantity in the opposite direction. This is because 3 orders are sent.

For example, say you are long 1 when you call ExitLong and then EnterShort . Since you are long 1, NinjaTrader will see that and a signal to ClosePosition. However, then when you call EnterShort(), the platform hasn't had enough time to actually close out the initial entry.

Now, you have an ExitLong(), ClosePosition, and then EnterShort(), resulting in an extra order which causes your quantity to double.

Please read this forum post for a detailed explanation:

Please let me know if I can assist further.

Thanks so much NinjaTrader_Gaby for the information! That's exactly the mistake I had made as I didn't know EnterLong() / EnterShort() automatically reverse the position.
