VWAP is the one reference line that institutional desks and retail scalpers actually share. It answers a question a moving average can't: not just where price has been, but where the volume actually traded. Here's what VWAP is, how its three common forms differ, and how intraday traders use it.
What VWAP is
VWAP stands for Volume-Weighted Average Price — the average price over a period, weighted by the volume traded at each price level. Where a simple moving average treats every bar equally, VWAP gives more weight to the prices where the most business got done.
That single difference is why VWAP matters more than a moving average for intraday work: it approximates the average price participants actually paid. Large desks benchmark their fills against it — "did I buy below VWAP?" — so it functions as a shared, real reference for fair value rather than just a smoothed line. Price above VWAP means the average participant is in profit on the day's longs; below, the reverse. That gives an intraday bias at a glance.
The three forms you'll meet
Session VWAP. The default. It resets at the start of each session and accumulates through it, so it always reflects the average price for the current session only. This is the "VWAP" most platforms plot. Because it resets, early-session VWAP is jumpy and stabilises as volume accumulates through the day.
Anchored VWAP (AVWAP). Instead of resetting on a fixed schedule, anchored VWAP starts from a specific bar you choose — a notable swing high or low, a gap, an earnings release, a session open. From that anchor it accumulates forward, measuring the average price paid since that event. It's powerful for asking targeted questions: "what's the average price of everyone who bought since the breakout?"
Rolling VWAP. A continuous, moving-window version that doesn't reset — it weights a fixed lookback of recent bars by volume. It behaves more like a volume-weighted moving average and is useful when you want a persistent fair-value line that ignores session boundaries.
For NQ specifically, session anchoring is where this gets interesting: a VWAP anchored to the NY cash open describes fair value for the US session, while one anchored to the London open frames the European tape. Which one is relevant depends on the session you're trading.
How intraday traders use it
A few honest, common uses:
- Fair-value reference. Price stretched well away from VWAP is, by definition, far from the session's average traded price — a mean-reversion context, not a signal on its own.
- Intraday bias. Trading persistently above VWAP leans bullish for the session; below, bearish. A reclaim or loss of VWAP can mark a shift in control.
- Dynamic reference level. VWAP often acts as a magnet and a pivot intraday — price returns to it, reacts at it, and uses it as a reference for continuation or rejection.
- Band centerline. Because VWAP is a fair-value line, it makes a natural centerline for deviation bands: measure how stretched price is relative to VWAP rather than to a simple average.
That last use is exactly where VWAP meets the TradeScorer framework. PDB Pro offers VWAP, NY VWAP, London VWAP, and Rolling VWAP as centerline options, so you can frame percentile stretch around true volume-weighted fair value instead of a plain moving average.
The honest caveat
VWAP is descriptive, not predictive. A tag of VWAP doesn't cause a reaction — it marks a level a lot of participants care about, which is why reactions cluster there. And session VWAP's early-session instability means it's least reliable exactly when the session is youngest. Treat it as one well-grounded reference among several, not a system in itself.
FAQ
What is VWAP? The Volume-Weighted Average Price — the average price over a period weighted by the volume traded at each price. It represents the average price participants actually paid, which is why it's used as a fair-value benchmark rather than a simple moving average.
What's the difference between session VWAP and anchored VWAP? Session VWAP resets at the start of each session and accumulates through it. Anchored VWAP starts from a specific bar you choose — a swing high, a gap, a news event — and accumulates from there, measuring the average price paid since that event.
Use VWAP as a band centerline
The Percentile Deviation Bands Pro engine lets you anchor adaptive stretch bands to session, NY, London, or rolling VWAP — so "far from fair value" becomes a measured, comparable reading on your NQ chart.
