Expert initialization failed by using MathArctan2\atan2

New comment
 
I can't test or run expert advisor Whenever I use MathArctan2\atan2.

I use Print(MathArctan2(-10,10) or atan2 (-10,10)).

Btw the first parameter of this formula is y in MQL5 Refrence, but x is the first parameter in the signature of function...

Perhaps you should read the manual. Arctan only takes one parameter, as does every other Math Function. There is no arctan2.

Perhaps you should read the manual. Arctan2 takes two parameters. 🤣 Just messing with you William!

Can you please provide sample code where that happens to you please, so that we can replicate the problem?

I just tried the following and it printed with no problem on MT5 build 3210:

int OnInit()
{
   Print( "ArcTan2: ", MathArctan2( -10, 10 ) );
   return(INIT_SUCCEEDED);
};

My apologies. I thought I did bring up the 5 docs.

I've just created a new template, and added yours to OnInit(). Still get the same error.

Don't use a template or other code, as there may be other things there messing things. Open a clean chart, and add my EA as is to it, and show the results.

EDIT: Also, what log output are you showing (Experts or Journal)? I don't recognise your output format for either. If its the Tester, it still does not seem in the format I usually see? Or is the log from an Test Agent?

Something seems wrong on your setup. What build are you using?


Please show the full Journal log output of the run in the Visual tester, as well as the Journal and Expert log output when attaching it to the terminal chart directly (not via tester).

I'm using build 2361.

It only happens when I'm using MathArctan2/atan2 function.

I can use MathArctan/atan function without problem...
