What is OBV (On-Balance Volume)?

On-Balance Volume adds volume on up closes and subtracts on down closes — running total.

Formula

If close > prior close: OBV = prior OBV + today's volume If close < prior close: OBV = prior OBV − today's volume If close = prior close: OBV = prior OBV (unchanged)

Indian market context (NSE)

Reference levels: Nifty 50 at 24,300, Reliance Industries at ₹1,300, Bank Nifty futures at 55,000 (lot size 30). Examples below show how OBV (On-Balance Volume) shows up on Indian index, equity, and futures books — update to live quotes in your journal.

Nifty 50 perspective

On-Balance Volume on Nifty (24,300): on the 15-minute chart, combine with session VWAP and 9:15–10:00 liquidity — index on-balance volume signals misfire on expiry Tuesdays without volume confirmation.

Reliance Industries perspective

On-Balance Volume on Reliance at ₹1,300: daily vs hourly settings diverge around results and ex-dividend dates; note corporate events in journal when on-balance volume readings spike.

Bank Nifty futures perspective

On-Balance Volume on Bank Nifty futures (55,000): first-hour signals differ from post-14:30 behaviour; avoid standalone entries when banking names lead the move.
