In trading, VWAP stands for volume-weighted average price. It is the average price a market has traded at since a chosen start point, with busier periods counting for more. Traders usually see it as a single line on an intraday chart, showing whether price sits above or below that average.
In short: VWAP multiplies price by volume, adds it up, then divides by total volume. It usually resets each session, while an anchored VWAP starts from a point you pick. Spot forex has no central exchange, so on forex and many CFD charts the line uses tick volume or the platform's own data, not true market volume.

How is VWAP calculated?
A normal average treats every candle the same. VWAP does not. A candle with a lot of volume pulls the line towards its price more than a quiet candle does.
There are four steps, repeated for each new candle:
- Find the typical price of the candle: the high, low and close added together, then divided by 3.
- Multiply the typical price by the candle's volume.
- Add that to the running total of price times volume since the start point.
- Divide the running total by the total volume since the start point.
As a formula, VWAP = running total of (typical price x volume) / running total of volume.
Worked example (illustrative)
Here are the first four candles of a session on a made-up index CFD. All the prices and volumes are invented to keep the sums simple. The first candle has a high of 20,010, a low of 19,990 and a close of 20,000, so its typical price is 60,000 divided by 3, which is 20,000.
Candle | Typical price | Tick volume | Price x volume | VWAP so far |
|---|---|---|---|---|
1 | 20,000 | 1,000 | 20,000,000 | 20,000.00 |
2 | 20,020 | 500 | 10,010,000 | 20,006.67 |
3 | 20,020 | 500 | 10,010,000 | 20,010.00 |
4 | 20,005 | 2,000 | 40,010,000 | 20,007.50 |
By candle 4, the running total is 80,030,000 and total volume is 4,000, which gives 20,007.50.
A simple average of the same four typical prices is 20,011.25. VWAP is lower because the busiest candle, with half of all the volume, had one of the lower prices.
How do traders use VWAP during the day?
Most traders use VWAP as a reference line, not as a signal to buy or sell. It shows where the market is now compared with the average price so far this session.
Common ways of reading it:
- Market bias: price holding above the line suggests buyers have been in control so far, and price holding below it suggests sellers have. It describes what has happened, not what happens next.
- Stretch from the average: some traders watch how far price has moved away from the line. Others add bands set a chosen distance above and below it.
- Pullbacks in a trend: in a steady move, some traders watch how price behaves when it returns to the line.
- Judging a fill: large desks often compare the price they got with VWAP to see how well an order was filled.
Some scalpers keep it on a fast chart. Others read it next to price structure ideas from smart money concepts, such as a liquidity sweep, or next to a momentum tool like RSI, which measures something different.
VWAP has limits. It is based only on past trades, so it lags price and predicts nothing. It also gets slower through the session: by late in the day so much volume is in the total that one more candle barely moves the line. In a strong trend, price can stay on one side of it for hours.
What is anchored VWAP?
Anchored VWAP is the same calculation with a start point you choose, instead of the start of the session. Traders often anchor it to a clear high or low, a large price gap or a major news release. The line then shows the average price since that moment.
Using the example above, say you anchor at candle 2. You leave out candle 1 and add up candles 2 to 4. The running total is 60,030,000 and the volume is 3,000, which gives 20,010.00.
So the same chart now has two lines: 20,007.50 from the session start and 20,010.00 from the anchor. The anchored line depends entirely on the point you picked, and if you choose your anchor after seeing what price did, it can look more useful than it really was.
Can you trust VWAP on forex and gold?
You can use it, but know what the line is made of. VWAP depends on volume, and the quality of that number varies by market.
Spot forex has no central exchange. Trades happen across banks, brokers and other venues, so nobody has one complete figure for the volume of a pair. Forex charts therefore tend to show tick volume, or data from the platform's own feed. Spot gold also trades over the counter, so a gold CFD chart usually has the same issue.
Tick volume counts how many times the price updated, not how much was traded. Traders often use it as a rough stand-in for activity, but it is not the same thing. Two platforms can also show different VWAP lines for the same market, because their data differs. So treat the line as an estimate, not an exact price.
Whether you can plot VWAP at all depends on your chart platform, so check yours first, including what volume data it uses.
How does VWAP work on index CFDs?
The volume issue applies here too. An index is a calculated number, not something traded on its own. The shares in it and the futures on it trade on exchanges with reported volume, but a CFD is priced by its provider, and the volume on its chart may be tick volume or the platform's own data.
The start point also matters more on index CFDs. Many of them trade for most of the day, while the underlying shares only trade during exchange hours. A VWAP that resets at the chart's midnight includes hours of quiet overnight trading, while one anchored to the US cash open leaves them out. That can give clearly different lines on the same chart, so check when yours resets. Our guide to trading sessions explains why activity changes through the day.
Point values and contract sizes vary by instrument, so use the lot size calculator to size a trade before you place it, and set your stop loss from your plan, not from the line alone.
How does this work under prop firm rules?
If prop firms are new to you, start with what a prop firm is. VWAP is an indicator, not a trading strategy, and it is not named on Alpha Capital's list of prohibited trading strategies. These are the rules most likely to matter if you trade around the line. Each one links to its help centre article.
The 2-minute rule
The 2-minute rule applies to all accounts. The average length of your trades and the majority of your trades must be over 2 minutes, and at least 50% of the relevant profit must come from trades over 2 minutes. Quick in-and-out trades off the line on a fast chart can pull those numbers down.
Adding to a trade at the line
Scaling in is allowed, with at least a one-minute gap recommended between entries on the same asset. But 3 or more positions, each opened within 60 seconds of the previous one as part of the same trade idea, count as position spamming.
Max Risk Rule
The Max Risk Rule applies to Qualified Accounts bought after 21 July 2026. It limits open drawdown on any one asset: 3% on $5,000 to $25,000 accounts, 2% on $50,000 to $200,000 accounts, and 1% on Alpha Direct at all sizes. Reaching the limit closes the account.
Three details matter here. Losing positions on the same asset are combined, and profitable ones do not offset them. All trading costs, including commissions, swaps and slippage, count towards the threshold, so the help centre recommends leaving a buffer. And if you close a trade and open another on the same asset in the same direction within 10 minutes, the losses from both are combined.
That last point catches repeat entries. If you keep buying each time price comes back to VWAP, those trades can form one continuous chain. The chain only ends once more than 10 minutes pass between one trade closing and the next one opening.
News windows
A release can move price well away from VWAP in seconds. In evaluations you can trade freely during news. On Qualified Alpha Pro, One, Three and Direct accounts, the news rules say you cannot open or close trades on affected instruments within 5 minutes either side of a listed release. Alpha Swing has its own 2-minute rule around news.
Automated VWAP systems
The Expert Advisor article limits EAs to risk management and trade assistance, and says automated EAs that execute trades on their own are prohibited and will close the account.
Drawdown limits and profit targets apply however you find your trades. Our Alpha Capital rules guide covers them in full.
Frequently asked questions
What does it mean when price is above VWAP?
It means price is above the average traded price since the start point, weighted by volume. Many traders read that as buyers having had the upper hand so far. It is not a buy signal on its own, and price can fall back through the line at any time.
Does VWAP reset every day?
Standard VWAP usually resets at the start of each session, but the exact time depends on your platform and settings. Anchored VWAP does not reset on a timer. It runs from the point you choose.
What is the difference between VWAP and a moving average?
A moving average usually looks back over a fixed number of candles and gives no extra weight to volume. VWAP starts from a fixed point, keeps adding to its total and weights each candle by its volume.
Can you use VWAP on forex?
Yes, if your platform offers it. But spot forex has no central exchange, so the line normally uses tick volume or the platform's own data. Treat it as a rough guide.
Is VWAP on Alpha Capital's list of prohibited strategies?
No. VWAP is not named on the list of prohibited trading strategies. The normal rules still apply to the trades you take, including the 2-minute rule, position spamming, the Max Risk Rule on Qualified Accounts and the news windows. If you are unsure about a specific setup, ask support before you trade it.
