Volume Profile Explained: Value Areas, Nodes and POC
The volume bars along the bottom of your chart answer one question: when did people trade? Volume profile answers a different and more useful one: at which prices did they trade? It is a horizontal histogram that plots total traded volume at each price level over a chosen session or range, instead of over each unit of time.
That single change reveals where a market spent its money, which is not always where it spent its time.
Below: what the point of control and value area mean, how the 70% band is calculated with real numbers, and where the tool misleads Indian traders.
The three readings that matter
Ignore most of the settings in a volume profile tool. Three outputs carry almost all the information.
Point of control (POC)
The single price level with the highest traded volume in the profile. It is the fairest price by consensus, where the most buyers and sellers agreed to do business. Price returning to a POC often stalls there, because that is where the most positions were opened.
Value area, VAH and VAL
The band of prices holding roughly 70% of the profile’s volume. Its upper edge is the value area high (VAH), its lower edge the value area low (VAL). Inside the value area, the market is balanced. Outside it, price is in discovery mode and moves faster.
High and low volume nodes
A high volume node (HVN) is a fat bulge: heavy trade, agreement, and later, sticky support or resistance. A low volume node (LVN) is a thin gap: few trades, disagreement, a zone price crosses quickly rather than settling in. LVNs make better stop zones than round numbers, because little business was done there.
How is the value area actually calculated?
The rule is mechanical. Start at the POC, then keep adding the heavier of the two adjacent rows until you have captured 70% of total volume.
Take an illustrative Nifty futures session bucketed into 25 point rows, total volume 10,00,000 units.
| Price row | Volume | Running total from POC | Status |
|---|---|---|---|
| 25,200 | 40,000 | Not reached | Outside value |
| 25,175 | 70,000 | Not reached | Outside value |
| 25,150 | 1,10,000 | 6,90,000 | VAH |
| 25,125 | 1,80,000 | 4,20,000 | Inside value |
| 25,100 | 2,40,000 | 2,40,000 | POC |
| 25,075 | 1,60,000 | 5,80,000 | Inside value |
| 25,050 | 90,000 | 7,80,000 | VAL |
| 25,025 | 60,000 | Not reached | Outside value |
| 25,000 | 50,000 | Not reached | Outside value |
Follow the arithmetic. Total volume is 10,00,000, so the 70% threshold is 7,00,000 units.
- Start at the POC, 25,100, with 2,40,000.
- Compare the row above (25,125 at 1,80,000) with the row below (25,075 at 1,60,000). Take the larger. Running total: 4,20,000.
- Compare 25,150 at 1,10,000 with 25,075 at 1,60,000. Take 1,60,000. Running total: 5,80,000.
- Compare 25,150 at 1,10,000 with 25,050 at 90,000. Take 1,10,000. Running total: 6,90,000.
- Still short of 7,00,000. Compare 25,175 at 70,000 with 25,050 at 90,000. Take 90,000. Running total: 7,80,000, which crosses the threshold.
The value area therefore runs from 25,050 to 25,150, with the POC at 25,100. Those three numbers are your map for the next session: 25,150 is where sellers took control, 25,050 is where buyers did, 25,100 is the magnet between them.
What does the shape of a profile tell you?
Profiles fall into a few silhouettes, each implying a different plan.
- D shape, fat in the middle: a balanced, rotational session. Fade the extremes back towards the POC.
- P shape, bulge at the top: short covering or a rally accepted high up. Bullish while price holds above the bulge.
- b shape, bulge at the bottom: long liquidation. Bearish while price stays under the bulge.
- Thin and vertical: a trend day with no agreement. Do not fade it; expect the next session to revisit the untested middle.
- Double distribution, two bulges and a thin waist: two value zones, with an LVN between that price crosses fast.
How do traders use volume profile in practice?
A simple, repeatable framework beats a screen covered in profiles.
- Mark yesterday’s VAH, VAL and POC before the open.
- Note where today’s open sits: inside yesterday’s value area suggests rotation, well outside it suggests a directional day.
- Trade towards the POC when price is stretched beyond value with no follow-through volume.
- Trade away from value when price accepts a level outside the VAH or VAL, holding there for several candles on rising volume.
- Place stops beyond the nearest low volume node, not at a fixed point distance.
- Use a longer composite profile, say 20 sessions, to find the levels that actually matter for swing positions.
Volume profile is not a signal generator. It tells you where to be interested, and you still need a trigger. Traders usually pair it with a VWAP reading or classic support and resistance levels, and it sits comfortably alongside a pivot point framework since both produce advance levels rather than lagging signals.
Where volume profile misleads Indian traders
Three practical problems, none obvious from a tutorial.
First, the data source. Cash volume is reported across exchanges, and your charting tool may show only NSE volume, only BSE volume, or a blend. Two platforms can hand you different POCs for the same stock on the same day. Pick one source and stay with it.
Index profiles are the worst offenders, because a cash index has no traded volume of its own. Most traders build them from the front month futures contract, which works until rollover week, when volume splits across two expiries and the profile thins out artificially.
Second, thin stocks. A profile needs enough trades to mean anything. On a stock turning over a few thousand shares a day, one institutional order creates a fake POC. The same caution applies to reading open interest against volume in illiquid contracts.
Third, profile length. A one day profile answers a day trader’s question, a one year profile a positional investor’s. Taking an intraday trade off a yearly POC produces levels price ignores for weeks.
A plain risk note: volume profile describes trade that has already happened. It carries no forecast, and past levels break regularly when news arrives.
Frequently Asked Questions
Is volume profile the same as market profile or TPO charts?
No, though they look alike. Market profile, or TPO, counts how much time price spent at each level, one letter per time bracket. Volume profile counts how many shares or contracts traded there. Time and volume usually agree, but when they disagree, volume is the better guide because it reflects committed money.
Which volume profile settings should a beginner use?
Start with a session profile, a value area of 70%, and row height set for 20 to 40 rows across the day’s range. Change one setting at a time and watch how the POC shifts. Most platforms also offer a visible range profile, useful for swing levels once you are comfortable.
Can I use volume profile for options trading?
Indirectly. Build the profile on the underlying, usually the index futures, and use its VAH, VAL and POC to choose strikes and stops. Do not build a profile on an individual option contract: its volume reflects strike-specific activity that shifts as price moves, so the levels carry no meaning across sessions.
Does volume profile work for long term equity investing?
It can flag accumulation zones on a multi-year composite profile, a reasonable place to add to a position you already believe in. But valuation, earnings quality and balance sheet strength decide long term outcomes. Treat the profile as an entry refinement tool on top of fundamental work, never a substitute for it.
Why does price often reverse exactly at the previous day’s VAH?
Because that is where sellers last outweighed buyers, and resting orders often remain there. Traders who sold near that level look to defend it, while traders who bought above it and got hurt look to exit at breakeven. Both flows appear at the same price, which is why the reaction is visible even without any news.
What does it mean when price opens outside yesterday’s value area?
It signals that overnight information has changed the market’s idea of fair value. If the first hour holds outside the old value area on strong volume, expect a directional day and stop hunting for mean reversion. If price slides back inside, the gap is being rejected and yesterday’s POC is the likely destination.
Key Takeaways
- The POC is the highest volume price and acts as a magnet; the value area is the 70% volume band between VAH and VAL.
- Value area construction is mechanical: from the POC, keep adding the heavier neighbouring row until 70% is captured, which gave 25,050 to 25,150 above.
- High volume nodes hold price, low volume nodes get crossed quickly, so LVNs make better stop zones than round numbers.
- Match profile length to trade horizon: session profiles intraday, composite profiles for swing positions.
- An open inside yesterday’s value area argues for rotation; acceptance outside it on volume argues for a trend day.
- Index profiles come from futures volume, not the cash index, so treat rollover week with caution and keep one data source.
