Hello morfeo360,

Thanks for your post.

To track and manage orders that are placed by the strategy the orders would need to be tracked as Order objects. Then, you could get information about those Order objects or manage orders using OnExecutionUpdate() and OnOrderUpdate().

See this reference sample that demonstrates tracking and managing Order objects as well as an example of using OnExecutionUpdate() and OnOrderUpdate(): https://ninjatrader.com/support/help...and_onexec.htm

See this reference sample for information about monitoring stop loss and profit target orders: https://ninjatrader.com/support/help..._and_profi.htm

And, see this reference sample about modifying stop loss and profit target orders: https://ninjatrader.com/support/help...of_stop_lo.htm

Note that when you dynamically change the stop loss price or profit target price in the strategy, you should always reset the stop loss or profit target price / offset value when your strategy is flat. Otherwise, the last price/offset value set will be used to generate your stop loss order on your next open position. This is noted on the Set method help guide pages linked below.

SetStopLoss(): https://ninjatrader.com/support/help...etstoploss.htm
SetProfitTarget(): https://ninjatrader.com/support/help...ofittarget.htm

Let me know if I may assist you further.

Is there a way to modify the stop loss of an OCO. I keep getting an error. OCO ID cannot be reused.

Hello,

Thank you for your post.

OCO (One-Cancels-Others) IDs need to be always unique for each grouping and cannot be re-used. When an OCO ID has been used with an order that is filled, rejected, or cancelled, any future orders using the same OCO ID will result in this error.

This often occurs with SetStopLoss() and SetProfitTarget() as well as with Atm Strategies, should one of the exit orders be rejected. For example, the stop is submitted with OCO ID ‘12345’ at an invalid price and is rejected. The target is attempted to be submitted with the same OCO ID ‘12345’, however errors the OCO cannot be re-used as this was used with the stop order, which was rejected.

To prevent the strategy from being deactivated, you can set the strategy's RealtimeErrorHandling property to IgnoreAllErrors or StopCancelCloseIgnoreRejects. With this property set, you can then trap order rejections in OnOrderUpdate if you would like to have the strategy attempt a different action. For example, you could call ExitLong() to exit the position, or you could use ExitLongStopMarket/ExitLongLimit to place other protective orders.
