On Balance Volume Formula
OBV is a cumulative indicator that continuously adds or subtracts volume depending on whether price closes higher or lower than the previous period.
If Close ↑ → OBV = Previous OBV + Volume
If Close ↓ → OBV = Previous OBV - Volume
If Close = Previous Close → OBV Unchanged
Up Volume
When today's closing price is higher than yesterday's closing price, the current volume is added to OBV.
- Represents buying pressure.
- Suggests accumulation.
- Supports bullish trends.
Down Volume
When today's closing price is lower than yesterday's close, the current volume is subtracted from OBV.
- Represents selling pressure.
- Suggests distribution.
- Supports bearish trends.
Why Does OBV Work?
Joseph Granville believed that volume moves before price.
Large institutions and smart money frequently enter positions gradually. Their activity often appears first in volume before it becomes obvious in price movement.
Volume Precedes Price
One of the core principles behind OBV is that volume changes often occur before major price movements.
Rising OBV + Flat Price = Hidden Accumulation
Falling OBV + Flat Price = Hidden Distribution
Relationship Between Price and Volume

|---|---|---|
| Rising | Rising | Bullish Confirmation |
