The trading world can be daunting, especially when dealing with the uncertainties of the stock market. Knowing what is trading volume can help you make more informed investment decisions. While it may sound confusing, trading volume is simply the total number of shares or contracts that were traded for a security over a certain period of time.
Understanding this metric helps you understand how actively traded a security may be and the investor sentiment regarding it.

What is trading volume?
Trading volume is the total number of shares or contracts exchanged between buyers and sellers during a trading session. It reflects how actively a stock or security is being traded. High volume suggests strong market activity, while low volume points to limited participation. Volume can apply to stocks, options, futures and other securities.
Where can you find trading volume?
Volume information is widely available from the following sources:
- Stock exchange websites like BSE and NSE.
- Mobile trading apps from banks or brokers.
- Financial news portals and market data terminals.
- Company websites in the investor section.
Trading volume significance
Now that you know where to find volume data, the next step is understanding what it may be telling you. Volume alone shows how active trading is — but when viewed alongside price changes, it may offer clues about investor sentiment and whether a price move has broad support or is just a short-term fluctuation. Traders often use volume alongside price charts to assess market behaviour, interest levels, and potential changes in price direction, which they can then use to make trades.

What does trading volume indicate?
The trading volume importance emerges when trying to gauge market sentiment. Volume can reveal:
- Price trends: When prices go up or down on high volume, the move is generally seen as more meaningful – that is, the trend, whether rising or falling, has the potential to sustain for some time.
- Potential reversals: A sudden spike in volume after a long uptrend or downtrend may suggest that the trend is losing steam and could reverse.
- Breakouts vs. false signals: A breakout above resistance (or below support) is more likely to sustain if backed by strong volume. If volume is low, the breakout might not hold.
- Liquidity: Stocks or funds with high trading volume tend to have better liquidity, meaning they are easier to buy or sell without significantly affecting the price.
Why is trading volume important?
Trading volume importance is that it can help support or add context to price movements.
- Supports price trends: Strong volume during an uptrend or downtrend is often seen as adding credibility to the move.
- Hints at potential reversals: A spike in volume after a prolonged trend may suggest a possible change in direction.
- Suggests market sentiment: Higher volume can reflect stronger interest or participation, while low volume may point to indecision.
It’s important to note that volume doesn’t guarantee outcomes, but it may offer clues about the strength behind market activity:
Volume and price: How are they related or unrelated?
The relationship between volume and price is not fixed:
- Aligned moves: Rising price with rising volume can signal stronger momentum and more strength of the price trend.
- Momentum trading strategies use this analysis to inform investment decisions.
- Unrelated moves: When price moves without volume support, such moves may not last or may reverse quickly.
- Divergence: If price rises but volume falls, it may signal a potential reversal.

Conclusion
Knowing what is volume in stock market trading gives investors a relative view of market sentiment and liquidity. Volume acts as the connection between price movement and sentiment. However, it’s important to note that none of these indicators are guarantees of stock market movements – they can only add weight to an existing trend or signal it’s potential to continue or reverse. Before making any investment decisions, consider volume alongside other indicators.
While trading based on volume and price patterns may appeal to active participants, mutual funds typically follow a long-term, buy-and-hold investment approach — guided by professional fund managers who select and manage portfolios based on research, diversification, and asset allocation strategies. This can be suitable for investors who prefer a hands-off approach, value professional management, want to participate in the potential growth of the stock market but seek relatively lower risk, and are focused on long-term wealth creation rather than short-term market movements.
FAQs:
How is trading volume calculated?
Trading volume is calculated by adding up all the shares or contracts that exchanged hands during a given timeframe. For example, if 1,000 shares of a stock trade on Monday and 2,000 on Tuesday, the total volume for those two days is 3,000 shares.
How to calculate volume in stock market trading?
Calculating trading volume essentially means summing all trades for the period. Beginner-friendly brokers often show daily volume automatically. You can also download CSV files from exchange websites and sum the “Quantity” column. This manual approach helps you learn the basics of volume analysis.
What is volume in stock market?
What is volume in stock market asks the same question as trading volume. It measures the total transactions of shares or contracts over a period. Volume differs from market capitalisation (market cap reflects a company’s total stock value). Investors watch volume to confirm trends. If you see a sudden spike in volume, it means more participants are joining at that price level. This can hint at a shift in supply and demand.
Does trading volume affect stock price?
Trading volume does not directly set the stock price. Instead, it shows how many participants are active at current prices. However, high volume often accompanies strong price moves. When many buyers enter, they may push prices up. Conversely, heavy selling volume can drive prices down. Low volume can lead to volatile price swings. Thin markets amplify each trade. This risk makes understanding volume critical when planning trades.
What does a high trading volume indicate?
High trading volume indicates strong participation. Key points:
- Increased interest: News, earnings, or events may be driving trades.
- Reliable price moves: Trends backed by volume tend to last.
- Liquidity: Easier to enter or exit positions in stocks.
However, not all high-volume days signal good trends. Study the reason behind the spike. A sudden sell-off can also generate high volume and warn of a downturn.
What does low trading volume indicate?
Low trading volume suggests limited participation. This can mean:
- Weak trends: Fewer traders support price moves.
- Wider spreads: Brokers set larger buy-sell gaps to manage risk.
- Higher volatility: Small trades can move prices sharply.
