What is Trading Volume?

Trading Volume is the total number of shares bought and sold during a given time period. Volume confirms the strength of price moves: high volume on a price advance confirms bullish conviction; high volume on a decline confirms bearish conviction. Low-volume moves are less reliable.

Trading Volume — Indian Stock Market Example

A breakout of Nifty 50 above a resistance level on volume 2x the 20-day average is considered far more reliable than a breakout on below-average volume. Many Indian traders track "volume shockers" — stocks with unusual volume spikes — as early indicators of institutional activity ahead of announcements.

Frequently Asked Questions about Trading Volume

What is relative volume and why does it matter?

Relative volume = current volume ÷ average volume for the same time period. Relative volume above 2 means twice the normal activity — a significant signal. Unusually high relative volume often precedes news announcements, block deals, or fundamental catalysts. Low relative volume on a breakout is a warning sign.

How does NSE/BSE report volume data?

NSE and BSE report total traded volume and total traded value for each stock daily. Volume is available in shares; traded value in rupees. Most charting platforms show volume as bars at the bottom of charts. Intraday volume builds throughout the day, with surges typically around market open (9:15–9:30 AM) and close (3:00–3:30 PM IST).
