How to draw a text

 

Hi,

 I would like to create an indicator with an arrow and a text of what the arrow means. Does anyone know how to do it? Or better still have a source code for an indicator that does it. THANKS.

 Here is an example below.

 

an arrow and a text 

 
It is already possible, when you mouse over an indicator, to see what that indicator is from.  If you want to do the on screen marking, and leave it there as you are showing for every indicator item, you stand a very real possibility of quickly cluttering your chart to the point of unreadability.

 I possible don't make myself clear either.  I would like to script this in MQL4.
