Hello 

i have a question

I want to get a value string || indicator_buffers to my EA. 

But I don't know what to do now?

This is my code EA

//THIS MY EA

#property link      "https://www.mql5.com"
#property version   "1.00"

void OnTick()
  {
        // how to get ValSend and array A[]?
	if(ValSend=="Good")
	-->> Buy and using A[]
	else
	-->> Not run
}



 

Here is your indicator:

Thank you very much!

I have relied on that to implement my ideas.

one more time thank you very much :)

 
SMA9 only sums range-1 values.
