Hi,

Last Beta version, was working OK.

Since I've downloaded the new release, my EA does not work anymore.

I still have to figure out what's going wrong.

Great !

Maybe you just have to re-compile them, have you tried it?

I also have this fault. E.g. the standard RSI indicator does not work anymore. It does not show a graph. And an EA using it can not load RSI indicator (error code 4805). Is it working for someone else?

Now that MQL5 have the matrix library, I recommend that MT5 develop built-in machine learning library to meet the needs of The Times.

With a shared project, we could build it together :DDD

It seems that in portable mode (&Win10) playing sound isn't working correctly.

Solved - how, I do not know.

After Win-Update and reboot all wav-files were gone, when I copied them back it worked.
