Volume Weighted Average Price VWAP
The average price weighted by volume — the institutional benchmark for the session.
Quick answer: VWAP is the volume-weighted average price of an instrument over the session, showing the true average price at which trading occurred and serving as the benchmark institutions measure their execution against.
In simple words
VWAP is the average price of the day, but weighted by how much volume traded at each price — so prices where a lot changed hands count more than prices where little did. It resets at the start of each session and builds through the day, giving a single line that represents the fair average price so far. In India it is the reference line for intraday trading: institutions try to buy below VWAP and sell above it, so price above VWAP is broadly bullish for the day and below it bearish. Traders use it as a magnet for mean reversion, as dynamic support and resistance, and as a bias filter.

How Volume Weighted Average Price looks on a chart
VWAP is a single intraday line that resets each session. Price above VWAP signals a bullish intraday bias and price below it a bearish one; price tends to revert toward VWAP, which also acts as dynamic support and resistance.
Professional explanation
Why VWAP is the institutional benchmark
Large institutions cannot buy their entire position at once without moving the market, so they work orders through the day and measure the quality of their execution against VWAP. A fund that buys its Nifty futures position at an average price below the day's VWAP has beaten the benchmark; buying above it means underperforming. This makes VWAP the single most watched intraday reference on Indian desks — price trading below VWAP is where institutions prefer to accumulate, and their buying there creates the mean-reverting pull back toward the line that discretionary traders exploit.
Bias, mean reversion and dynamic support/resistance
VWAP serves three roles at once. As a bias filter, price above VWAP means the average buyer of the day is in profit — a bullish intraday tone — and below it, bearish. As a mean-reversion magnet, price that stretches far from VWAP tends to be pulled back toward it, so fading extremes toward VWAP is a common intraday tactic. As dynamic support/resistance, in a trending session price repeatedly pulls back to VWAP and bounces (uptrend) or rallies to it and rolls over (downtrend), giving low-risk trend-continuation entries.
Standard-deviation bands
Many traders add VWAP bands — one, two and three standard deviations of price around the VWAP line, similar in spirit to Bollinger Bands but anchored to the volume-weighted mean. Price reaching the upper band is stretched above fair value and prone to revert; reaching the lower band is stretched below. The bands turn VWAP from a single line into a full mean-reversion framework, defining how far is 'too far' from the session's fair price.
Anchored VWAP
Standard VWAP resets each session, but Anchored VWAP lets a trader start the calculation from any chosen bar — a major swing high or low, an earnings gap, a budget-day open, or the start of a rally. The anchored line then represents the volume-weighted average price of everyone who has traded since that event, making it a powerful reference for whether buyers or sellers from that pivot are in control. Anchored VWAP from a significant Nifty or Bank Nifty swing often acts as a durable support or resistance far beyond a single day.
Formula
Volume Weighted Average Price formula
VWAP = Σ(Typical Price × Volume) / Σ(Volume), where Typical Price = (High + Low + Close) / 3
The sums are cumulative from the session's (or the anchor's) start. VWAP resets at the start of each new session unless it is an anchored VWAP.
- Typical Price — (High + Low + Close) / 3 for each bar, representing that bar's average price
- Volume — The volume traded during each bar
- Σ(TP × Volume) — The running cumulative sum of price times volume since the session or anchor start
- Σ(Volume) — The running cumulative total volume since the session or anchor start
How it is calculated
- For each bar, compute the typical price as (High + Low + Close) / 3.
- Multiply the typical price by that bar's volume.
- Keep a running cumulative total of those price-times-volume products since the session start.
- Keep a running cumulative total of volume since the session start.
- Divide the cumulative price-volume total by the cumulative volume to get VWAP; it updates each bar and resets next session.
Interpretation & signals
Traders read price above VWAP as a bullish intraday bias and below as bearish, treat VWAP as a mean-reversion magnet and dynamic support/resistance, and use the standard-deviation bands to judge when price is stretched too far from fair value.
Buy / bullish signals
- Price is above VWAP and pulls back to test VWAP as support in an uptrending session, then bounces.
- Price reclaims VWAP from below with rising volume, flipping the intraday bias bullish.
- Price tags the lower VWAP band (stretched below fair value) and turns back up toward VWAP.
- Price holds above an anchored VWAP drawn from a significant swing low, showing buyers from that pivot are in control.
Sell / bearish signals
- Price is below VWAP and rallies to test VWAP as resistance in a downtrending session, then rolls over.
- Price loses VWAP from above with rising volume, flipping the intraday bias bearish.
- Price tags the upper VWAP band (stretched above fair value) and turns back down toward VWAP.
- Price is rejected at an anchored VWAP drawn from a significant swing high, showing sellers from that pivot are in control.
False signals to beware
- Early in the session VWAP is based on little data and whipsaws around price, giving unreliable signals in the first few bars.
- On a strong trend day price can ride far above or below VWAP without ever reverting, so fading it fails.
- On thin or gappy instruments VWAP is distorted; it is meant for liquid intraday markets.
Settings, timeframe & conditions
Advantages & limitations
Advantages
- The single most watched intraday benchmark on Indian desks, so it is self-reinforcing.
- Combines price and volume into one fair-value line.
- Serves as bias, mean-reversion magnet and dynamic support/resistance at once.
- Anchored VWAP extends its usefulness to swing and positional timeframes.
Limitations & disadvantages
- Standard VWAP is intraday only and resets each session, so it has no multi-day memory.
- Unreliable in the opening bars when it is based on little data.
- Fails as a mean-reversion tool on strong one-way trend days.
- Meaningless on illiquid instruments with poor volume data.
Combining Volume Weighted Average Price with other indicators
- Volume Profile — VWAP and the Point of Control often align on a key value level; when they coincide, that price is a powerful intraday magnet and support/resistance.
- Volume Weighted Average Price — Pair session VWAP for the day's bias with an anchored VWAP from a major swing to see intraday and swing fair value at once.
- Exponential Moving Average — Use a fast EMA for micro-trend direction and VWAP for the session bias; entries aligned with both are higher-probability intraday.
Practical examples (Nifty & Bank Nifty)
NIFTY example
Nifty opens at 24,100 and spends the first hour building a VWAP around 24,120. Price then trends up and, on every pullback, dips to VWAP near 24,150, 24,190 and 24,240 and bounces — VWAP is acting as dynamic support on a trend-up day. A trader buys the VWAP retests with a stop just below the line, riding the intraday trend, and stands aside once price loses VWAP and closes below it, flipping the bias bearish.
BANKNIFTY example
Bank Nifty gaps up and stretches to the upper 2-standard-deviation VWAP band, far above the session's fair value of 51,400. Given Bank Nifty's tendency to mean-revert intraday, a trader fades the extension back toward VWAP rather than chasing the gap. Separately, an anchored VWAP drawn from the previous week's swing low at 49,800 sits at 51,050 and has acted as support on three pullbacks — a durable reference well beyond a single session.
Common mistakes
- Trading VWAP signals in the first few minutes when the line is based on almost no data.
- Fading price back to VWAP on a strong trend day where it simply never reverts.
- Applying standard session VWAP to daily or weekly charts, where it is meaningless.
- Ignoring the difference between resetting session VWAP and a persistent anchored VWAP.
Professional usage
Institutions use VWAP as their execution benchmark — algorithms slice large orders to buy below and sell above the line — which is precisely why it works as a discretionary reference: everyone is watching it. Professional intraday traders use it as the session bias filter, take trend-continuation entries on VWAP retests in trending sessions, fade the standard-deviation bands in balanced sessions, and use anchored VWAP from significant pivots (budget day, results, major swings) to judge whether buyers or sellers since that event hold the advantage. It is almost always the backbone reference of an Indian intraday setup.
Key takeaway
VWAP is the volume-weighted average price of the session and the benchmark institutions trade against, which is why it is the central line of Indian intraday trading. Price above it is bullish and below it bearish for the day; it acts as a mean-reversion magnet and dynamic support/resistance, and anchored VWAP extends the same logic to swing trading.
