Strategy crash

[fLife]

Hi,
I've been experiencing crash/error which occurs every 12 hours or so.
It happens only when my strategy is active.
The attachements are the error message and how it looks like on the chart. How can I fix it? - I can provide the strategy code, if needed.
Thanks for any help.

fLife, welcome to our forums - are you working on native OCO handling here for your script with the IB account connection?

Hi, yes - currently running on demo account, but connected to IB

Thanks, then I would suggest rerunning this setup with the OCO handling for your IB demo account connection set to local mode.

So the error could be occuring because of using demo? If it was real account, it would not have happened?

Overfills generally could always happen, it's the same as for example an inflight execution you did not expect when trading manually.

However in your case I feel the combination of the demo paper account at IB with the native oco handling did favor to see it occuring.

Thank you for your replies. I just noticed, that when I switched connection settings on my IB connected account to Local OCO simulation. all my opened positions on that account disappeared. After I turned Local OCO simulation OFF, it appeared again.
Why did this happen?

UPDATE:
I loaded the positions while running OCO - this one is solved

I am still getting the same error - message attached
