// Formula Name: Market Profile 
//
// Use with 5/15min chart
// Originial - From AFL library
// Edited by - Milind / KAKA
// AFL Modified by Rajandran- code works good in 5min, 15min, 30min timeframe
// Letter A now repeats for first 30 min, Letter B next 30 min so on
// Multiple Repeating Alphabets Horizontally to be fixed in 5min and 15min
