Market sessions and Volume profile - By Leviathan

This script allows you to keep track of Forex market sessions (Tokyo, London and New York), as well as Daily, Weekly and Monthly sessions. All of them are accompanied by Volume Profile options where you can view VP Histogram, Point of Control, Value Area High and Value Area Low.
Colors, lines and other design preferences are fully customizable.

* Volume Profile of shorter sessions (eg. Tokyo, London, New York) works better when using lower timeframes such as 15min, 5min, etc.
** Use timeframe higher than 15min when viewing Monthly sessions
