In Build 1421 it is not possible to call the test.dll file. It only worked on Build 1420.

I tested Build 1421 on a Xeon Silver CPU and apparently everything worked fine. But on the Xeon E5 2650 CPU it is not working.

Hello guys, is there any update on this problem? I also have a problem with two math functions: MathCeil and MathRound. MathCeil returns completely wrong results while MathRound returns 0 as a result. This is on new MT4 build 1421 and Windows 10 Pro. Older builds of MT4 terminal on the same computer don't have this problem.

Hi! The problem is solved by choosing a different processor on the VPS server. This has already been verified by my friends.

this is not a solution, it is a workaround... I already have workaround but it not optimal.
