array out of range error

New comment

An MQL4 function I've created and used before in prior MT4 versions is now yielding an "array out of range error" in my EA in latest version of MT4. I've searched around and can't find an answer. The error is referencing the line:

 Level = Levels[j]; 

after the word "Levels"

How do I fix this? 

 Thanks

   double TopLevel = 0;
   double Level = 0;

...

for(int j=0; j<=ArraySize(Levels); j++)

...
It should be "j < ArraySize(Levels)" and not "<=".

That works. Thanks Fernando!

Good day to you Fernando,

I get a similar sort of error message, but there is no "ArraySize" anywhere in the code of my indicator.

Any suggestions please?
Thanking you sincerely for replying.
Hercs.

  1. Don't Hijack other threads for your off-topic post. Next time, make your own, new, thread.

  2. Indicators don't need ArraySize, they have automatically resized buffers.

  3. Do you really expect an answer? We can't see your broken code — we can only guess. There are no mind readers here and our crystal balls are cracked.

  4. You are likely looking past the end of the buffer.
