I already arranged And thank you for explaining to me what you did in the code. I compared the code I sent and the code that you sent and I understood the lines of command you made.
My problem is that I was putting it inside another folder. example:

Indicators / folder / indicator.ex4
Instead of being indicators \ indicator.ex4
Thank you very much.
Now I know some more of the code

I went to test it
unsuccessfully
Line 1 = buffer 0
Line 2 = buffer 1

Both continue zero
I liked your solution, although it does not solve this one, I think it solves in my other 6 indicators

What did you do with the indicator? Because this error always appears in other indicators, so I'd like to know how to solve them

Use the trace block to check the value of the indicator.
I am having a similar problem, in my case, the block trace back zero and at the end of the back test the chart does not appear my custom indicator, only the default ATR indicator also used as reference

I sent my custom indicator to FXdreema but it seems that the expert advisor does not recognize the indicator. see the photo
http://prnt.sc/e6gppa
On one side a real-time chart of the indicator with block trace marking test 01 = zero and atr = 0.0013 ...
In the right chart if you see a back test with only the ATR on the chart, it was to appear the indicator Teste01
.
Do you realize that only the ATR indicator was called by the expert?
The Test01 indicator does not appear in this call. So it is always marking zero.
I saw in another post that the problem could be the lack of compatibility of the fxdreema with the indicator.
How to solve this?
