VWAP (Volume Weighted Average Price)

The VWAP is the session's average price weighted by volume: every trade counts for the quantity it moved. It was not born as a chart indicator but as an execution benchmark on institutional desks: whoever has to buy a huge block is judged by comparing their average price with the day's VWAP. This makes it different from almost everything else in the catalogue: around the VWAP there are not just eyes — there are real orders, execution algorithms working precisely at that level.

In plain terms — The VWAP is "the price paid by the average participant" since the open. If the market trades above it, the average buyer is in profit; below it, at a loss. Price returning to the VWAP puts the average participant in front of a choice — and their reaction tells you who controls the day.

How it is calculated

VWAP = Σ (typical price × volume) / Σ volume, from the session open

with typical price = (high + low + close)/3 for each bar. It is a cumulative sum: early in the day the VWAP moves a lot, then the weight of history makes it ever more stable. Many platforms add bands at ±1 and ±2 standard deviations (volume-weighted), marking the normal excursion from the average price.

The difference from a moving average: the average looks at a sliding window, the VWAP looks at the whole session from a fixed anchor and weights by volume. It does not lag the way averages do: it consolidates.

How to read the chart — An intraday session: dashed vertical line at the open, VWAP in gold, dashed ±1σ bands. Interactive — the highlighted points show price returning to test the VWAP, the institutional benchmark role, and the session reset.

Price stretches away from the VWAP and comes back to test it: the reaction at that level is one of the most watched intraday reads.

Reading it in practice

Intraday bias — price steadily above the VWAP: a buyer-controlled day, where pullbacks to the VWAP are continuation opportunities; below: the reverse. The level matters most in the first hours, while the average is still contestable.
The VWAP test — price returning to the level after a push is the informative moment: a clean bounce = control confirmed; an accepted cross = the day may be changing hands.
Band extensions — at ±2σ from the VWAP on a trendless day, price is statistically stretched: a mean-reversion zone for intraday traders. On a trend day the same extension can simply persist — the usual regime distinction.
Anchored VWAP — the multi-day variant: same formula, anchored to an event (a major low, earnings, a breakout). It measures the average price of everyone who entered from that event onward.

Limits and traps

Warning — The VWAP is a session tool: it resets at every open. Late in the day it is nearly immobile — using it as a "responsive" signal at 5 pm means reading an average that can no longer change. Weight and meaning fade as the hours pass.

On markets without an official session (crypto) the anchor is a convention (midnight UTC, the weekly open): it must be stated, not assumed — see market hours and sessions.
The VWAP is descriptive, not predictive: it says where the session has traded, not where it will.
