What Is On-Balance Volume (OBV)?

OBV measures buying and selling pressure as a cumulative indicator, adding volume on up days and subtracting on down days.

Quick Answer

OBV measures buying and selling pressure as a cumulative indicator, adding volume on up days and subtracting on down days.

What Does OBV Measure?

On-Balance Volume (OBV) was developed by Joe Granville in 1963. It creates a running total of volume, adding the full day's volume when price closes higher and subtracting when price closes lower. OBV often moves before price, making it a leading indicator for potential breakouts or breakdowns.

Formula:
If close > previous close: OBV = Previous OBV + Volume; If close < previous close: OBV = Previous OBV - Volume
