A VWAP trading strategy uses the volume weighted average price, the average price of the session weighted by how much traded at each price, as a reference line for intraday trades. Price above it suggests buyers have been in control on the day; price below it suggests sellers have. We use it as a guide to context and location, never as a trigger on its own.
Quick answer: what is VWAP and how do traders use it?
VWAP (volume weighted average price) is the session’s average price, weighted by volume, and it resets at the start of each day. Day traders use it as a fair value line: they look to buy pullbacks to VWAP in an uptrend, sell rallies to it in a downtrend, and avoid trading around it when price keeps crossing it.
What VWAP measures and how it is calculated
A simple moving average treats every bar the same. VWAP gives more weight to the bars where more trading took place, so it shows where most business was actually done during the session.
The calculation runs bar by bar from the session open:
- Work out each bar’s typical price: (high + low + close) divided by 3.
- Multiply the typical price by that bar’s volume.
- Keep a running total of step 2 and a running total of volume.
- Divide the first running total by the second. That is the current VWAP.
Because the totals keep growing, VWAP moves a lot in the first hour and little by the afternoon, so an early cross means less than a late one. If volume itself is new to you, our guide on how to use volume to confirm a trend covers the basics.
VWAP on forex: the tick volume caveat
Spot forex has no central exchange, so there is no single, complete record of how much traded at each price. When you add VWAP to a forex chart, most platforms weight it by tick volume instead: the number of price changes in your broker’s feed during each bar.
Tick volume often rises and falls with real activity, but it is a proxy from one feed, not a count of contracts or currency traded. Many index and commodity CFD platforms also use their own tick data, so check what your platform uses before you trust the line to the pip.
In our experience VWAP is most useful on markets with exchange-reported volume, such as futures, and on major pairs during the London and New York sessions.
A VWAP trading strategy in three setups
We treat VWAP as a line showing which side of the day has control. Three uses come up again and again.
1. Pullback to VWAP in a trending session
When price has held above a rising VWAP for most of the morning, a pullback to the line is where buyers who missed the move often step in. We want a clear rejection candle at or near VWAP, ideally where it lines up with a level we had already marked. The bearish version is a rally to a falling VWAP. Many intraday traders mark daily pivots alongside VWAP; see pivot points trading.
2. Reclaim or rejection of VWAP
If price opens below VWAP, then climbs back above and holds for several bars, control may be shifting. A failed attempt to reclaim, where price pokes above and closes back below, says the opposite. We read these as context for a trade at a level, not as entries by themselves.
3. Stretch away from VWAP
Some traders plot bands one or two standard deviations either side of VWAP and fade moves to the outer band, expecting a return to the average. That is a form of mean reversion trading, where price snaps back to an average, and it works best on range days. On a strong trend day, price can ride the outer band for hours.
Anchored VWAP: choosing your own starting point
Standard VWAP resets at the start of every session. Anchored VWAP starts the calculation from a bar you choose, such as a major swing low, a gap, or the candle of a big news release. It then shows the volume weighted average price of everyone who has traded since that event.
That makes it useful for swing traders as well as day traders. If price holds above a VWAP anchored to the low of a new uptrend, buyers since that low are, on average, in profit. The catch is that the anchor is a choice, so pick it for a reason you can write down, not to fit the line to the chart.
VWAP vs a moving average
| Factor | VWAP | Simple moving average |
|---|---|---|
| Weighting | By volume | Every bar equal |
| Resets | Each session (unless anchored) | Never; rolling window |
| Best timeframe | Intraday charts | Any timeframe |
| Forex data | Tick volume proxy | Price only |
| Typical use | Fair value for the day | Trend direction |
Our guide to the moving average crossover strategy covers rolling averages in more depth. VWAP is closer in spirit to the value area high, low and point of control, which also map where volume was done.
Worked example: a pullback to VWAP on an index
All figures are hypothetical. On a £6,000 account we risk 1% per trade, which is £60. An index has opened higher and held above a rising VWAP all morning.
- Context: price pulls back to VWAP at 8,200, which also sits on the previous day’s high, a level marked before the open.
- Entry: a 5-minute candle rejects the area and closes at 8,205. We buy at 8,205.
- Stop: 8,185, below the rejection low and clearly back under VWAP, so 20 points of risk.
- Size: £60 divided by 20 points is £3 per point on a spread bet. See how to calculate position size for spread bets and CFDs.
- Target: the session high at 8,245, 40 points away, so the potential gain is about £120.
If price falls through 8,185, we lose about £60 plus spread, more if a fast market fills the stop at a worse price. Spread bets are leveraged, so losses build quickly when size is not set from the stop.
Common mistakes with VWAP
- Buying every cross above VWAP. On a range day price crosses it again and again; we stand aside then.
- Trusting early readings. In the first half hour VWAP is built on very little data and moves sharply.
- Forgetting the forex caveat. On spot forex the line is weighted by your broker’s tick volume, not real traded volume.
- Using session VWAP on daily charts. It resets every day, so it says little about multi-week trends.
- Ignoring levels. VWAP works best alongside key levels that you rank before the session, not as a stand-alone reason to trade.
Leverage magnifies all of these. The US regulator’s investor site notes that day trading with leveraged strategies can lead to substantial losses, even more than you put in, so treat any intraday method with care.
Frequently asked questions
Does VWAP work on forex?
It can, with a caveat. Spot forex has no central volume, so the line is weighted by tick volume from your broker’s feed, which is a proxy rather than real traded volume.
What timeframe is best for VWAP?
Session VWAP is built for intraday charts, typically 1-minute to 15-minute. For swing trades on 4-hour or daily charts, anchored VWAP from a meaningful swing point is more useful.
Is price above VWAP bullish?
It means buyers are in control so far today. It is not a reason to buy by itself; the trade still needs a level, a stop and a target.
Why does VWAP reset every day?
Standard VWAP measures the average price for one session, so it starts again at each open. Anchored VWAP lets you start from any bar you choose instead.
