The Developing Value Area High (dVAH) is the real-time upper boundary of the value area as it develops throughout the current trading session, representing the highest price within which approximately 70% of volume has been traded so far. Unlike the fixed VAH from a completed session, the dVAH changes dynamically as new volume data is added during the day. Intraday traders use the dVAH as dynamic resistance and watch for price reactions at this level to make trading decisions.
Example
“Price tested the dVAH at 4,210 three times during the morning session, failing to break above each time, which the trader interpreted as intraday resistance.”
