Hello, after some review of the strategy, i have found that the problem is a SETParabolicStop.
the stop is OnStateChange and State.Configure
What could be the error

[NinjaTrader_Jim]

Hello memonic,

Thanks for your question.

SetParabolicStop will create stop levels that will move close and close to the market price, provided the market price is moving in a steady direction. As the movement of the stop is parabolic, the distance it moves increases with each update. This can cause the calculated level to be placed on the other side of the market depending on the movement of the market.

As this can be a real world possibility, I may suggest to add code to trap rejections and failures to change orders so you can take a different action when the order is error is seen. This involves using Order objects, OnOrderUpdate, and RealtimeErrorHandling. I have included documentation items below and an example strategy that demonstrates how Order objects can be used.

RealtimeErrorHandling - https://ninjatrader.com/support/help...orhandling.htm

OnOrderUpdate - https://ninjatrader.com/support/help...rderupdate.htm

Please let me know if there is anything else I can do to help.
