Scale-in Order management

[dwrety]

Hello NinjaTrader Team

I am working on a price action scale-in order management. The logic goes as this (long example): Once my 1st entry limit long is filled, I place a stop/target order for that. In the meanwhile I place a 2nd limit buy order at 50% pull back of the price action setup (the full range of the painted bars), and change my first target order to breakeven. During that time, if my first target is filled, I will cancel my 2nd limit buy (2nd buy is always above the stop loss). I found the scale-in order works if the 1st and 2nd order are filled on the same bar, however the scale-in order will not get filled on the subsequent bars.

Here are some visualization.



The 1st limit buy is submitted within OnBarUpdate() while the scale-in order is submitted within OnExecutionUpdate(), basically, I want the 2nd order to be submitted if I am already holding a position.

Is there something I am missing? Thank you very much.

If these are managed orders, are you repeating the scale-in order on subsequent bars? Or, did you set the "good until canceled" flag when you placed the order? If no to both, it would automatically cancel at the end of the bar on which it was placed.

You are right. And I just fixed the problem. This seems like a silly question from me. Sorry I am new to NT coding. Thank you very much.

Hello dwerty,

Thanks for your post.

I am happy to see you have found a resolution to the behavior you were reporting.

QuantKey_Bruce has noted something that is important to keep in mind when using the Managed Approach for order handling. By default, orders submitted via Entry() and Exit() methods automatically cancel at the end of a bar if not re-submitted. This is noted on the Managed Approach help guide page below.

Managed Approach: https://ninjatrader.com/support/help...d_approach.htm

You could set the isLiveUntilCanceled property is set to true the order will NOT expire at the end of a bar but instead remain live until the CancelOrder() method is called or its time in force is reached. Please refer to the help guide link below regarding Exit methods and the isLiveUntilCanceled property.
