OBV (On Balance Volume) · सहायता केंद्र | ट्रेडर्सवीक

OBV keeps a running total that adds the bar's volume on an up-close and subtracts it on a down-close. Rising OBV confirms the buying pressure behind an uptrend; OBV/price divergence often precedes a reversal. Copy the version for your platform.
