Future week Calendar; Each day's custom sessions & Labels

On-Chart Calendar for the week ahead with 4x customizable intraday sessions (each day with it's own unique sessions)

-add your own text labels and optional time/date stamps to each session; for key events of the week.
-toggle on/off each individual session.
-Choose number of weeks of history to show (default is 0: only show upcoming week.
-Works on BTC too (includes Saturday/Sunday sessions).

//Notes//
~timestamps and labels anchor to the start of the session box
~when using with default 'weeks back to show' = 0; Session boxes will disappear as price passes through their right hand side.
~to remove the very long indicator status line (due to so many sessions): Go to chart settings >> status line, and under 'indicator' toggle off 'arguments'

Example usage: Each day's 4x custom sessions showing; only upcoming week; no labels

Example usage: Each day's 4x custom sessions showing; Showing 1 week of history too; no labels
