TPO (Time Price Opportunity) / Market Profile chart model.

Market Profile charts show price distribution over time by placing a letter (A, B, C, …) at each price level touched during successive time periods (typically 30-minute brackets). The resulting profile reveals key structural levels:

  • POC (Point of Control) – price with the most TPOs.
  • Value Area – price range containing the configured share of TPO activity.
  • Initial Balance – range established during the configured opening period.
  • Single Prints – levels touched during only one TPO period.

Use to_tpo_profiles to transform OHLCV bars into per-session TPOProfiles.
