Hello tkaboris,

Thank you for your note.

I suspect the message has to do with the stop loss and profit target orders, which are submitted using OCO (one cancels other). I see you are submitting an entry order and then calling the SetStopLoss() and SetProfitTarget() methods. These methods are meant to be called prior to submitting an entry order, then as soon as the entry is executed the stop and target orders are submitted. I suggest adjusting your strategy so that it calls SetStopLoss() and SetProfitTarget before calling your EnterLong() or EnterShort() methods and this should resolve the OCO error. For more details on SetStopLoss() and SetProfitTarget() please see the links below:

• https://ninjatrader.com/support/help...ofittarget.htm

We also have a couple of reference samples that utilize the Set() methods for stops and targets that you may review:
