Transparent Boxes Get Darker

[tchapman]

Hi,

I have developed an indicator to highlight the asian session range using a transparent rectangle. Unfortunately when I display 4 charts on screen the opacity of the boxes appears to get darker with each chart. I have attached an image and the code of the indicator.

Any suggestions?

Thanks,

Tim

Please try my attached change, this uses just one tag id and does not generate a unique one.

Thanks Bertrand, I managed to figure out what was happening. The code was drawing a new rectangle in the same range for each bar in the session. This gave the impression it was getting darker with each timeframe.

Cheers,

Tim
