TPO (Market Profile)
Time Price Opportunity — ATAS/CBOT style visualization. Shows color blocks stacked left to right for each time period the price visited a level. More blocks = more time price spent at that zone.
Key levels
POC
Point of Control — level with most TPOs
VAH
Value Area High — upper boundary of 70%
VAL
Value Area Low — lower boundary of 70%
POC acts as a price magnet. The Value Area (VAH-VAL) contains 70% of activity. Price outside VA tends to return; price escaping VA with volume indicates new range.
Sessions
Each session generates its own TPO profile with different colors. Blocks stack horizontally left to right showing the temporal sequence of visits to each level.
