Expert initialization failed by using MathArctan2\atan2

pavelion #: I'm using build 2361. It only happens when I'm using MathArctan2/atan2 function. I can use MathArctan/atan function without problem...

That build is much too old. We are currently on build 3210. Are you perhaps still using it on a 32bit OS?

If you are not able to update your build because of a 32 bit OS, then you will probably want to code your own version of the function using the normal arctan.

https://en.wikipedia.org/wiki/Atan2 — read the section "Definition and computation" for how to implement it using arctan

pavelion #: I'm using build 2361.

Support for the 32-bit platform version was discontinued 20.03, after the release of build 2361. We strongly recommend upgrading to the 64-bit MetaTrader 4 5 version in order to access all the platform's features without any limitation.

I didn't know the end of support for 32 bit OS.

Thanks all.
