Volume Analysis in Stock Trading: A Beginner's Guide

Open any NSE chart on Zerodha Kite or TradingView and you will see two layers stacked on top of each other. The candles on top, the vertical volume bars at the bottom. Most beginners stare at the candles and ignore the bars completely.

It is natural to watch the candles first. They move, they flash red and green, and they feel like the action — while volume looks boring by comparison. It stays boring right up until the day it keeps you out of a weak breakout that was about to trap your money.

That is the wrong half of the screen to ignore. Price tells you what happened. Volume tells you how much it mattered.

What volume really shows

Volume is the total count of shares that changed hands inside a given window. One day, one hour, one five-minute candle. Each transaction has a buyer and a seller, so a single trade of one hundred shares counts as one hundred, not two hundred.

On the chart, that count becomes a vertical bar under each price candle. A tall bar means a lot of shares moved during that candle; a short bar means very few.

Indian platforms report volume as a raw share count, not in rupees.

This sounds obvious. The interesting part is what those numbers represent at scale.

When Reliance trades two crore shares in a day, that is not two crore people taking small punts. The bulk of it is mutual funds, foreign investors and HNIs (high-net-worth individuals) working large orders through their desks.

They are obliged to fill those orders in the open market, and every completed trade prints on the tape. Think of the tape as the market's receipt printer: each finished trade leaves a printed slip, and all those slips added up are the volume.

So volume is the one place on the chart where big money cannot hide. Their actions show up as bars at the bottom of your screen, in real time, every day. Reading those bars is how a small retail trader peeks at what real money is doing.

Compare that to price by itself. A one percent rise in Tata Motors looks the same on the chart whether two crore shares pushed it up or twenty thousand shares did. The volume bar is what tells the two apart.

A one percent up day on the heaviest volume of the month is a different event from a one percent up day on the lightest volume of the month. The first shows conviction — meaning many buyers were willing to act at that price, not just a few stray trades. The second is drift.

How NSE reports volume

Two numbers get thrown around on Indian markets, and beginners often mix them up. Traded volume and delivery volume. Knowing the difference is the first real upgrade to your volume read.

Traded volume is every share that changed hands during the day. That includes intraday positions opened and closed inside the session, before the 3:30 bell. If a day trader buys five thousand HDFC Bank at 10 am and sells the same five thousand at 2 pm, those count as ten thousand in the day's traded volume even though no shares actually moved between demat accounts.

Delivery volume is only the slice that was actually taken into the buyer's demat account at the end of the day. NSE and BSE publish this number every evening as a delivery percentage of the day's traded volume — you can pull it stock by stock from NSE's security-wise archives.

A stock with seventy percent delivery had most of the day's activity end up as real overnight ownership. A stock with twenty percent delivery had most of the day churned by intraday traders who flattened out before the close.

For a swing trader or investor, delivery percentage can be a useful extra clue, because it separates intraday churn from shares that were actually carried home. A rising stock whose delivery percentage stays high over several sessions can suggest stronger overnight participation, not just day-trading froth.

A rising stock with a low delivery percentage, by contrast, might be little more than a one-day intraday squeeze that unwinds tomorrow.

Volume on the candle chart is the traded number, not the delivery number. Delivery comes in NSE's end-of-day bhavcopy, which Zerodha and most brokers expose under a separate panel. Use both, for two different reads.

One more practical note. Volume resets every day, so today's two-crore-share day in Reliance has nothing to do with yesterday's. To know whether today's number is heavy or light, you compare it to the stock's twenty-day or fifty-day average, which most platforms plot as a line across the volume bars.

The four price-volume setups

Once you start reading price and volume together, every candle on the chart drops into one of four bins. The bin tells you what the move means and whether it is worth trading.

Every price-volume read starts with two questions: did price rise or fall, and was volume above or below normal?

Those two questions create four basic stories. Price went up or down; volume was heavy or light compared to the twenty-day average.

The same logic applies to down candles. A down day on heavy volume looks like real distribution — large holders selling out — because sellers were aggressive and big positions were being unwound.

A down day on light volume is a different animal. Price fell because there were no buyers willing to bid up, not because sellers were pounding the table. Such drops deserve caution before you treat them as confirmed distribution; thin-volume falls are sometimes bought back.

Get just this much in your head and you have already built a habit most beginners never practise consistently. On every chart, ask two questions before you touch the buy button — which way did price go, and was volume above or below the twenty-day average. The answers together are your read.

Volume analysis examples on Indian charts

Theory is one thing. Watching it on real Indian names is what makes the lesson stick.

Adani Enterprises in 2022–23 is a useful illustrative case, not a controlled study. Through 2022 the stock rose for months, and on its clean breakouts above prior swing highs the volume bar often spiked well above the twenty-day average — a sign of real participation joining the move rather than paper churn.

Then on 24 January 2023, the short-seller Hindenburg Research published a report alleging stock manipulation and accounting problems at the group. Adani denied the allegations, calling them baseless.

A heavy sell-off followed, and Adani Enterprises fell about 28% in a single session on 1 February 2023 (CNBC). On those falling days the volume bars dwarfed anything in the prior rally — a picture of what selling on heavy volume can look like in real time.

Quarterly results days show the same physics on calmer large-caps like HDFC Bank. Results days often produce above-average volume, because that is when the market reprices a stock on fresh information. Whatever the result-day candle looks like, the jump in volume is the market voting in real time.

Smallcaps tell the opposite story. A typical SME or microcap might trade fifty thousand shares a day for weeks, then print a sudden eight-percent up day on a million shares.

That single bar is most of the signal. Someone may be accumulating a position — but a volume spike alone does not prove it. The next step is to check delivery, news, any bulk or block deals, and whether the stock is liquid enough to exit without moving the price against yourself.

The same smallcap on a normal day, where price moves three percent on twenty thousand shares, is just a few small orders pushing through a thin order book. The move looks the same as a real one on the price candle, but the volume bar tells you it is not.

This is why volume matters more on smallcaps than on large-caps. On Reliance or Infosys, even a quiet session has crores of shares trading because the float — the shares freely available to trade — is huge. On a smallcap, the difference between a real institutional entry and a couple of retail orders is the difference between a five-bagger and a stuck position.

Common volume mistakes

If volume is so useful, why do most retail traders ignore it or misuse it? Three habits are responsible for almost all the damage.

The first mistake is treating volume as a signal on its own. Beginners see a tall bar and assume something important happened, without checking the price candle on top.

A single huge volume bar with a tiny price move is often just two big participants crossing trades. It is information, not a trade idea by itself.

The second mistake is comparing today's volume to yesterday's instead of to the twenty-day average. Yesterday might have been a quiet sideways day with abnormally low volume.

Today's number looking large next to that means little. Always anchor to the stock's own average, not to a random neighbour candle.

The third mistake is forcing volume to confirm a position you have already opened. You bought the stock, the price moves up, and you celebrate the green candle while ignoring that volume is well below average. The move is real on the chart, but it does not have the backing you wanted, and the position is more fragile than you think.

There is also a structural issue with intraday volume that newer traders trip over. The normal NSE equity session runs from 9:15 am to 3:30 pm (NSE market timings), and the first and last thirty minutes of that session usually carry far more volume than the quiet middle of the day.

So comparing a 10 am five-minute candle to a 1 pm five-minute candle on volume alone can mislead you.

Most platforms partially solve this with average-volume lines that account for time of day. If yours does not, the fix is to compare intraday volume bars only to the same time of day on prior sessions, not to the rest of today.

How to actually use volume in trades

Volume is not a system. It is a filter that improves the quality of trades you would already have considered from price action and support and resistance.

Use it for three jobs, in order. Confirm breakouts. Validate reversals. Avoid traps in thin names.

For breakout confirmation, the rule of thumb is simple. A price close above a clean resistance level on volume at least one and a half to two times the twenty-day average is a more credible breakout. The same close on weak, below-average volume is a stronger candidate for a fakeout — a breakout that fails and snaps back — the next session.

For reversal validation, look at the volume on the rejection candle, not the run-up. A pin bar or engulfing candle off a major support level deserves real weight only if the rejection itself printed heavy volume. A reversal candle on thin volume is mostly hope.

For thin-name avoidance, set a personal floor. Many disciplined Indian swing traders avoid any position in a stock whose average daily traded value is below ten or twenty crore rupees. Below that threshold, your own buy and sell orders move the chart, and slippage — the gap between the price you expected and the price you actually get — eats most of the edge.

One small practical note about the indicators built on volume. Tools like On-Balance Volume, Volume Profile, Accumulation/Distribution, Chaikin Money Flow, and VWAP all repackage the same underlying tape into different shapes. They are useful, but learning them before you can read a raw volume bar against its twenty-day moving average is putting the roof on before the walls.

Start with the bar at the bottom of the chart and the average line across it. Add one extra volume tool at a time only when you can articulate what gap it fills. Most successful traders end up using one or two, not five.
