USDVWAP (Volume-Weighted Average Price) is an intraday benchmark that tracks the session’s average traded price while giving more influence to higher-volume trades. Because it recalculates as new trades print and resets each session, traders often treat it as a “fair value” reference for that day.
How VWAP Works
VWAP combines price and volume into one running average. The core idea is simple: add up how much value traded at each moment (price × volume), then divide by total volume so far.
In formula form, it’s commonly expressed as:
VWAP = Sum(price × volume) / Sum(volume)
Many charting platforms approximate this using “typical price” rather than tick-by-tick trade prices. Typical price is (High + Low + Close) / 3 for each candle. The platform then computes cumulative (typical price × volume) divided by cumulative volume from the start of the session.
VWAP is plotted as a single line on intraday charts and often looks smoother than a simple moving average (SMA) because it is volume-weighted.
Example
If a simple moving average is like averaging every candle equally, then VWAP is like averaging while letting the busiest candles “vote” more.
For instance, if most of the day’s volume trades near $100 and only a small amount trades at $105, VWAP will stay closer to $100 than a plain average would.
Why It Matters
Traders often read price above VWAP as trading above the session’s volume-weighted average and price below VWAP as trading below it—useful context for intraday entries, exits, and trend bias.
VWAP is also widely used as an execution benchmark: institutions may judge buy execution as better when fills are at or below VWAP, and sell execution as better when fills are at or above VWAP.
Risks or Limitations
VWAP is a lagging indicator because it only uses already-printed trades, so strong trends can remain above or below VWAP for long stretches.
It’s most reliable in liquid markets; in low-liquidity conditions, a few large trades can skew the line.
In crypto, “session” boundaries are not universal (markets trade 24/7), so VWAP can differ by platform depending on where the day resets and which venue’s volume feed is used.
