Simple Session timer with separate session for Asia, Europe, and the Americas plus an extra custom session timer. each can be turned on and off separately.
The indicator also plots the highs and lows of each session.
This code was modified from the Session timer code found in the original "The Arty" by PheonixBinary but expanded to better include all trading sessions.
The code was written in a manner to be as compact as possible. I had looked at many other Session timers and found entire input sections that were longer than the entirety of this indicator.
Please feel free to use this code in any manner you choose permission not required.
