TPO Unsplit (Optimized v5)

TPO Unsplit (Optimized v5) is a script that renders unsplit Market Profile (TPO) structures with precision and historical depth—ideal for traders who want a clean, collapsed TPO view across any timeframe. Unlike built-in TradingView Market Profile tools that rely on "expanded" (split) or "collapsed" profiles limited by chart scope, this tool provides full unsplit TPO shapes & HTN/LTN for prior completed sessions, rendered directly on your chart.

Key Features

• Unsplit TPO Profiles: Displays the full shape of each prior TPO session without splitting by sub-period.
  
• Historical Rendering: View TPOs across extensive historical data (up to 500 sessions), depending on row count and chart resolution.
  
• Custom Timeframe Configuration:
  Chart Interval determines the sub-period granularity (e.g. each "letter" equivalent is a 5m bar on a 5m chart).
  Selected Session Timeframe (in the script settings) defines the full TPO session window (e.g. 30m, 1h, D, W, M, etc).
  
• Value Area & POC Visuals:
  Customisable drawing of Value Area High (VAH), Value Area Low (VAL), and Point of Control (POC).
  Colour settings for value vs non-value regions.
  
• Efficiency Controls:
  The Row Count input controls TPO resolution. Higher row count = more detail but shorter lookback.
  Lowering row count increases how far back profiles can be rendered (helpful on high-volume charts or low timeframes).
  
• Optimised Structure Rendering: Efficient block rendering using scaled vertical lines rather than characters. No letter labeling, but full TPO shape is accurately depicted.
  
• Alerts: Includes price-based alerts for interactions with the POC (in, above, or below).
  

Usage Notes

• The script only displays completed TPO sessions (i.e. the most recent full session). The current session is not shown while it’s forming.
  
• Because TPOs are based on time-at-price, this may resemble a volume profile visually—but it strictly counts time-based touches per price bin.
  
• Use on intraday, daily, weekly, or custom intervals. Designed for adaptability across instruments and strategies.
  

Example Use Case:

Set your chart to 5-minute candles, then choose a TPO session length of 2 hours in the settings. You'll see each completed 2-hour period plotted as a single collapsed TPO shape—providing a clean view of price distribution without noise.


Performance Tips:

• Default Row Count is 50 for balance between precision and depth.
  
• Increase for finer profiles, decrease to load more history.
  
• This is bounded by TradingView’s max_lines_count, so tuning is essential based on your asset/timeframe.
  

Disclaimer:
This tool is built purely on public Pine Script v5, compliant with TradingView's open-source requirements. It’s not based on volume but strictly follows the Steidlmayer TPO methodology using time-based logic.
