Sharing session indicator

Hi, I have a indicator that allow me to draw vertical line on any time and date, another cool features is when you load the indicator in several pairs, you only need to change the parameter of one pair, the other pairs will change itself. However, there is a problem I need a experience coder to give me a hand on, the indicator consume too much resources and cause ctrader to crash, 

so if you can modify the indicator but not significantly reduce the functionality, I will share the indicator and tell you how to look for trading setup in exchange.

Regards
