An indicator that displays the movement of the point of control (POC) and the value area (VA) of an asset over a certain period of time.
POC (Point of Control) is the price at which the maximum number of contracts was traded.
VA (Value Area) is the price range within which 70% of the total number of contracts was traded.
VAH (Volume Area High) is the upper limit of the value area.
VAL (Volume Area Low) is the lower limit of the value area.
POC, VAH, and VAL can serve as guidelines for market analysis and act as key levels.
