Happy Saturday everyone!
I created an indicator that displays the current session of the market, and it automatically calculates the GMT Offset of whatever broker you are using, so it’s plug and play.
As you can see, it paints a line on each bar for each session, along with a live view of which market is currently open in the lower right corner. It works on every time frame, however anything over H1 only displays the live session display.
I plan to list it for sale on the MQL5 Market, but I wanted to offer it up here first, because this forum has given me so much, and I want to give something back. There will be more indicators to come. 
I don’t foresee any issues with the indicator, but of course if you come across any please let me know.
Enjoy!
