Here's how to fix a problem with the Eurozone - General

Good afternoon.

I'm trying to use MQL5.I have disassembled exp_tema.mq5 and modified the code. Now I should print in log MA of each candle (last 20). But I don't understand why some entries are missing in the log. I noticed that if ma[3] is missing in log, then there is no ma[13]. Why is this happening? Where is the error there?

Here it is.

if(CopyBuffer(Handle[Number],0,0,20,ma)<0)

is obviously missing a check:

BarsCalculated >= 20
CopyBuffer==20

No need for a video.

Do a detailed Print in the code, so that we can see in the log what the intermediate variables are equal to.

If you run the debug EX5 not from the editor, but directly in the terminal - the same result?

Can you attach the debug EX5?

Can you attach debug EX5?

It's interesting, if I run it from tester, it gives 30, if I run it as EA, it also gives 30 on print.

If I go back to debug, it returns 0.

On what build and on what kind (excuse the expression) did it work.

I must still lay out the video will be, if no one else can not reproduce this miracle.

Thank you, I will try to add it.

Here is a video (but choose a resolution higher than 720, otherwise everything will be in soap)

Win7 64bit MT5 687 build

As I found out the effect when return gives 0 seems to happen only in debugger.

At the same time, if I use only the "step while" button, it seems to work.

If I enter while loop to exit with "step in" button, it doesn't work, the output is stably 0.

In general, the video shows everything, but how to be and what to do until I do not understand (and why is it so only me?)

However, I still have problems with buffers. Everything is clear when I read them, but I do not understand how they should be implemented in code. If it's not too much trouble, can you insert it into the code?
