Text inside indicator - page 4

New comment
 
investeo:

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 put the code with self-explanatory comments

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

The indicator for MT4 is called russian colors, you want

You only have to replace the HMA with EMA34
