I don't think 3800 is out yet, so which build?

If it's not 3800, its probably a beta build still with some bugs.

Yes, beta 3787, but hope they know it

this is really something wrong with the backtest quality.

Yesterday, I got 32%, then today I open again yesterday's backtest data..and voila..backtest quality is 99%. I was so excited that I forgot to do the documentation, then I backtested again and now the backtest quality is 0%!

After upgrading to 3800 build. My EAs cannot use TLS socket. This was working just before the update.

I've checked that certificates are fine. Wireshark shows just socket connection but no TLS handshake

It may be relevant to the following point in the announcement (first post):

12. Terminal: Enabled support for TLS 1.3 in web protocols. TLS 1.0 is considered deprecated and insecure and has therefore been disabled.

Hi

The Build 3800 not open in Windowns 10 after update


I try the install, not work too, the mt5setup.exe not execute too.

Build 3600 work fine.

I try the compattibility mode, but no way.

Install all available updates for your Windows 10, including packs.

Thanks for the reply, but it was the first thing I did.

And, not work, even the installer of the new version also does not open.

Check your antivirus. The installer is not related to a specific build, if it doesn't open it's a problem on your computer.
