The Description
The TPO Indicator gives the user a quick and easy way to view the key Market Profile® price levels of POC, Value Area High (VAH), Value Area Low (VAL), and developing POC, VAH, and VAL. It also allows the user
to review these values historically and see how price reacted when approaching these levels. While developing POC, VAH, and VAL change throughout the day, traditional Market Profile® charts only show the
current values. The TPO Indicator allows the user to look back and see where the levels were at any given historical time.
The RTL token for this indicator is TPO. When used in the language, in addition to the VA & POCs mentioned above, the TPO indicator provides the user access to IB High and Low, 2x and 3x IB Highs and Lows, TPO
counts, TPO counts above and below the POC (both with and without singles). These are very powerful tools for users interested in backtesting Market Profile® related strategies, or charting Market Profile® related data on traditional charts.
The Market Profile® enablement is needed in order to used this indicator.
Value Area (VA): Area where 70% of the TPOs (time-price opportunities) occurred.
Point of Control (POC): Price at which the most TPOs occurred.
For a more complete understanding of the Point of Control and the Value Area, review the documentation and videos on Market Profile Charts.
