Stop loss triggering twice

[andrewlin90]

I am running a tick based strategy that enters a long or short position based on a set of criteria in NQ. In my script, when a position is entered, a corresponding stop loss order is placed immediately. However, on rare occasions in the live environment, the stop loss order seems to be triggered twice, resulting in a net reversed position that is unwanted.

I am unable to figure out why this is happening and how to prevent it in the future. This is the first time in two weeks I've seen this happen, and on average this strategy makes about 4 trades a day. Has anybody run into this, and knows how to fix this?

Hello andrewlin90,

Thank you for reaching out.

Is the automated strategy you are working with, a strategy coded by yourself using the Strategy Builder, or was it acquired from a 3rd party?

If it is your own coded strategy, please contact our engineering team at

and they will be able to guide you in debugging the strategy.

If it is a 3rd party strategy, you would want to contact the developer for assistance with their software.


Also, you can send in your platform files so we can check for any underlying errors or issues that may be contributing to this.

Please send me your log and trace files so that we may look into what may be occurring.

You can do this by going to the Control Center-> Help-> Email Support

Ensuring 'Log and Trace Files' is checked will include these files. This is checked by default.

Here is a video on how to do so, for your reference:

Thanks in advance, we look forward to helping resolve this issue for you.
