Great forex sessions indicator. Very helpful for day trading.
 
Excellent indicator. Conveniently shows sessions + cool function with Ctrl to get session parameters at a specific point in time.

How did you choose the numbers 70 and 1.3 to calculate the height of the session block in the highlighted lines above?

If user uses a non-standard resolution or text scale, the block and text will appear distorted.

 
Thanks for this applicable and wonderful indicator.
 
A great effort and result
