I made a proof-of-concept EA interacting with an indicator through a temporary global variables changed by using different keystrokes.

Corners do work, but one has to remember that lower corners are relative to indicator frame, not  the timeline - see the video.

Unfortunately video upload does not seem to work on this forum :(


For the time being I put it on

Hi

The video does not contain audio track. I will post the code today in the evening because I left it on another laptop.

The code may not be very elegant, but works properly

Hi

thanks for posting the code,

could you please change the code in a way that the indicator simply puts some kind of text in the upper right corner,

a sample that can be used for every indicator in separate window

I need a suggestion for a simple indicator:

Close > EMA 34 = green historgam or ....line or....arrow...

Close< EMA 34 = reed  histogram or...line or....arrow...

Thanks for help

Hi Investeo

many thanks, your code works, i.e.the label shows up, but the value is not updating. Did I make a mistake?

Here is my code.

Yes, but should not follow the "curve of the indicator" but only indicate changing color.

Thanks walb
