Can you do for example about ErrorDescription ()  because i don't know how to write this 

Nope,  I would suggest that you don't use it . . ..  print the error number instead,  that way there is no possible misunderstanding about what the error is . . .

Now,  perhaps you might be good enough to answer my first question,  in post #2 of this thread . . .  if you do it will help you.

Rõ ràng là bạn không có ErrorDescription () chức năng xác định. . .

Yes ?

Yes. There are 2 problems that causing that :

1. The EA did not count the trade - how mant trade the EA should open or how many trade already opened.

2. The EA open position based on one MA above (or below) the other MA. In other words : The EA should not open when one MA above (or below) the other.

We will discuss the number 1 later. Right now we discuss the number 2 : The EA should not open when one MA above (or below) the other. So the question is, when should the EA should open the trade ? To answer this, why don't you attach 2 MA with different periods on a chart and imagine that you are the EA riding that 2 MA. 

Can you solve it ? 

Here's help : WHRoeder already answered that on page 1.

I see that you are banned from mql5.com. Well, mql5.com is for mql5 code, mql4.com is for mql4 code.

And I see that you're not writing the code yourself, you just copy paste from your old topic https://www.mql5.com/en/forum/142274
