Introduction
The On Balance Volume (OBV) indicator, developed by Joe Granville in 1963, translates volume flow into actionable trading signals. Unlike price, which shows past movements, OBV reveals smart money activity before major price shifts.
Key Insight
OBV is a cumulative indicator:
- Adds volume on up days (higher closes).
- Subtracts volume on down days (lower closes).
- The direction of the OBV line matters more than its value.
How OBV Works
Calculation Rules
- Today’s close > Yesterday’s close: Add volume to OBV.
- Today’s close < Yesterday’s close: Subtract volume.
- Today’s close = Yesterday’s close: No change.
