**Short answer:** VWAP, the volume-weighted average price, is the average price something has traded at so far today, weighted by how much traded at each price. It's a single line on your chart that tells you where the day's "fair" price is. Above it, buyers have been in control. Below it, sellers have.

## How VWAP is calculated

For every bar, take the typical price (high + low + close, divided by 3) and multiply it by that bar's volume. Add those up through the day, then divide by the total volume so far. That's it. Because heavy-volume bars count for more, a big move on big volume pulls VWAP much more than a drift on light volume.

VWAP resets every session. On stocks that's usually the 9:30 a.m. New York open. On futures it depends on your platform: many reset at the start of the overnight session, others at the regular open. Check yours, because two traders can be looking at two different VWAPs.

## Why big traders watch it

Funds and institutions are often judged on whether they bought below VWAP or sold above it. A big buyer who pays below the day's average did a good job. So a lot of real money cares where price is relative to VWAP, and that's why the line tends to matter on a chart.

## Three ways day traders use it

### 1\. As a trend filter

The simplest use: above VWAP, look for longs. Below it, look for shorts. It won't time your entries, but it keeps you from fighting the day's direction.

### 2\. As a level to pull back to

On a trending day, price often pulls back to VWAP and bounces. Some traders wait for that touch before getting in, rather than chasing the move.

### 3\. As a "too far" warning

When price runs far from VWAP very quickly, it often snaps back toward it. Mean-reversion traders fade those stretches. It's riskier, because on strong trend days price can stay away from VWAP all session.

## What VWAP can't do

- **It lags.** It's built from prices that already happened. It describes the day, it doesn't predict it.
- **It gets slow late in the day.** By the afternoon so much volume is baked in that VWAP barely moves.
- **It isn't a strategy on its own.** A line is not a plan. You still need an entry, a [stop](https://www.daytraderincome.com/stop-loss-explained/) and a [size](https://www.flltlt.com/blog/risk-management-for-funded-traders/?ref=daytraderincome.com).

## VWAP vs a moving average

A moving average gives every bar the same weight and rolls forward forever. VWAP weights by volume and starts over each day. A moving average answers "where has price been lately?" VWAP answers "where has today's money actually traded?"
