Strategy Tester crashed when using Indicator with FX Blue Trading Simulator New comment

Behdad Ahmadi 2019.08.02 18:30

I coded an Indicator which use a DLL file (I coded this DLL file to call Python function from C++). The Indicator works well on charts when trading without any bugs, but If I want it to use in FX Blue Simluator Visual chart to backtest it manually, MT4 crashes with this error:

What's the problem with Indicator?

Thank you
