Session TPO Market Profile

Introduction

Wikipedia:A Market Profile is an intra-day charting technique (price vertical, time/activity horizontal) devised by J. Peter Steidlmayer, a trader at the Chicago Board of Trade (CBOT), ca 1959-1985. Steidlmayer was seeking a way to determine and to evaluate market value as it developed in the day time frame. The concept was to display price on a vertical axis against time on the horizontal, and the ensuing graphic generally is a bell shape--fatter at the middle prices, with activity trailing off and volume diminished at the extreme higher and lower prices. In this structure he recognized the 'normal', Gaussian distribution he had been introduced to in college statistics.

Important : The market profile tool is designed to be used on the 30min timeframe, however, you can modify its parameters and use it on lower timeframes (15/10/5min)

This indicators displays the following information

• Session open
  
• TPO
  
• Value area calculation zone
  
• POC
  
• Highlight of Single prints
  
• Session High/Low
  
• The current price (TPO Profile is often used isolated without any candlesticks on it)
  

Parameters

• Session beginning configuration (not coded with a session input yet)
  
• Number of candles to use for calculation (default 13 for a single session)
  
• Extend yesterday's levels (VAH/VAL/POC)
  
• Show/Hide Market profile calculation area (background color)
  
• Bars number (number of rows that will be used to draw the profile)
  
• Show/Hide TPO's
  
• TPO Colors customization (For in/out of VA, VAL/VAH/POC/High/Low levels and single prints)
  
• Show/Hide High/Low levels
  
• Show/Hide VAL/VAH/POC Levels as lines
  
• Enable/Disable Single prints highlighting
  
• Value area size (as percent)
  
• Show/Hide current price (corresponding to a line scaled on the "close" price)
  

Additional Notes

• Each session is drawn when the day is over
  
• To use as much space as possible, TPO's are not directly drawn on the area of their calculation (which can be confusing if you use candlesticks directly over it)
  
• This script will probably be updated in the future (especially concerning its implementation which is a bit spaghetti coded for now).
  
• If you have interesting suggestions about new features that are usual within market profile tools and missing from this script , don't hesitate to suggest it.
