What is VWAP?

The average price of every trade over a period, weighted by how much traded at each price. Where the money actually changed hands, not where the candles went.

Updated September 4, 2026

Volume-weighted, and why that matters

A moving average treats every candle equally: a quiet hour counts as much as a violent one. VWAP does not. Each price is weighted by the volume traded there, so the number lands where the money actually went.

The practical difference is large. A thin overnight drift barely moves VWAP, while one heavy hour pulls it sharply. That makes VWAP a fair answer to "what did participants on average pay for this coin during the period" — a question a plain average cannot answer.

The line desks are judged against

VWAP exists because large orders cannot be filled at one price. A desk executing size over hours is measured on whether it beat the period VWAP — buying below it is a good fill, above it is a bad one.

That is why the level attracts reaction rather than because of any predictive property: a lot of automated execution is explicitly trying to trade around it, so real orders cluster there.

Above or below — what it actually says

Price above VWAP means buyers since the anchor are, on average, in profit and sellers are underwater. Below, the reverse. That is a statement about positions, not about direction.

It explains the common behaviour around it: a return to VWAP from above meets people who bought earlier and are happy to add, and a rally back to VWAP from below meets people who want out at breakeven. The level matters because of who is sitting at it.

The anchor changes everything

VWAP is meaningless without saying "since when". Session VWAP, weekly VWAP and a VWAP anchored to a specific event answer different questions, and they can sit far apart on the same chart.

The terminal lets you pick the window for exactly this reason. Match it to your horizon: a five-day VWAP tells an intraday trader little, and a session VWAP tells a swing trader little.

Common questions

How is VWAP different from a moving average?
A moving average weights every candle equally; VWAP weights each price by the volume traded there. On a coin with uneven activity the two can be far apart, and VWAP is the one that reflects where money actually traded.
Does price always return to VWAP?
No. It often does in ranging markets, which is where the reputation comes from, but a trending market can spend days on one side of it. "Away from VWAP" is not by itself a reason to expect a return.
Which VWAP period should I use?
The one that matches how long you hold. The anchor defines what the number means — the average price since the session opened is a different fact from the average price over the last five days.
