VWAP is the average traded price from a chosen starting point, weighted by volume. A trade made during a high-volume period affects the line more than a trade made during a quiet period. Standard VWAP normally starts at the session open and resets the next day.
Key takeaways
- VWAP is a cumulative average of price weighted by volume.
- Standard-deviation bands show distance from that average; they are not guaranteed reversal points.
- Anchored VWAP starts from a chosen event instead of the daily open.
- Daily VWAP resets, which limits its usefulness for multi-day swing targets.
The VWAP formula
For each bar, calculate the typical price:
Typical price = (High + Low + Close) ÷ 3
Multiply that price by the bar’s volume. Keep a running total, then divide by cumulative volume:
VWAP = Cumulative (Typical price × Volume) ÷ Cumulative Volume
Because both parts are cumulative, every new bar updates the line without erasing the earlier session activity.
How traders read VWAP
Price above VWAP means the market is trading above the session’s weighted average. Price below VWAP means it is below that average. A trader may define a tested rule around a hold, reclaim, rejection, or loss of VWAP.
The line alone does not prove that buyers or sellers will take control. It describes where trading occurred, not why the next trade must move.
What VWAP bands show
Many charting platforms add bands one or more standard deviations above and below VWAP. Those bands describe how far current prices sit from the weighted average under the indicator’s calculation.
Bands can frame extension or mean-reversion context. They do not make an extended market reverse automatically. Confirm the calculation and band settings on the charting platform because implementations can differ.
What anchored VWAP changes
Anchored VWAP uses the same cumulative idea but begins at a trader-selected event: an earnings gap, major low, breakout, high-volume reversal, or another meaningful date and time.
That makes it more useful across several sessions. It also adds discretion. Two traders who choose different anchors are studying different averages, so the reason for the anchor belongs in the written plan.
The honest swing-trading limit
Daily VWAP resets at the next session and is therefore mainly an intraday reference. It does not supply a forward-looking weekly or monthly destination. Anchored VWAP can follow a multi-day move, but it remains an average of price and volume recorded since the anchor.
A swing trader can use anchored VWAP for trend acceptance or invalidation context, then use prior structure, risk multiples, or options-derived price targets for the potential destination.
VWAP and options-derived levels answer different questions
VWAP answers: Where is the weighted average from this starting point?
Options-derived levels answer: Where may current options positioning create a price worth watching?
They can overlap, but neither guarantees a reaction. Read options-derived levels vs. VWAP for the side-by-side workflow.
Frequently asked questions
What does VWAP tell a trader?
VWAP shows the volume-weighted average transaction price from the chosen starting point. Session VWAP helps compare the current price with the average price paid during that session.
What is the VWAP formula?
Add typical price multiplied by volume for every period, then divide that cumulative total by cumulative volume. Typical price is commonly high plus low plus close, divided by three.
Is VWAP useful for swing trading?
Daily VWAP resets each session, so it is mainly an intraday reference. Swing traders can use anchored VWAP from a meaningful event, but it still summarizes past price and volume rather than forecasting a target.
Takeaway
VWAP is a useful average when the strategy defines how to react around it. Know where the calculation starts, what the bands measure, and whether a daily reset matches the holding period.
