VWAP Meaning: Understanding Volume Weighted Average Price
Volume weighted average price (VWAP) represents the average price a security has traded at throughout the day, weighted by volume. Unlike a simple moving average that treats all price points equally, VWAP gives greater weight to price levels with higher trading volumes, providing a more accurate representation of the true average transaction price.
VWAP is often used as a benchmark by institutional traders to evaluate execution quality. When pension funds or asset managers need to execute large orders, they use VWAP to assess whether they’re getting a reasonable fill price.
The indicator serves three primary functions in modern trading:
Price benchmarking for large order execution
Support and resistance identification for intraday trading
Trend confirmation for directional bias assessment
Most VWAP calculations reset at the start of each trading session — although settings may vary by platform — making it particularly valuable for day traders and market makers who need clean, session-specific reference points.
How Does the VWAP Formula Work?
The VWAP formula calculates a running average that accounts for both price and volume throughout the trading session:
VWAP = Σ(Price × Volume) ÷ Σ(Volume)
Breaking this down into practical steps:
Calculate typical price for each period: (High + Low + Close) ÷ 3
Multiply the typical price by period volume
Create cumulative totals of price-volume products
Divide the cumulative price-volume by cumulative volume
Time Period | Typical Price | Volume |
|---|
