What you'll learn

  • Explain what VWAP measures and why it resets every session
  • Calculate a simple VWAP from price and volume data
  • Use price location relative to VWAP to frame who is in control intraday

The idea

VWAP stands for Volume-Weighted Average Price. It is the average price paid for a stock today, where every price is weighted by how many shares traded there. A price where 500,000 shares changed hands counts far more than a price where only 5,000 did.

That makes VWAP the session's "fair value." Large funds are often judged on whether they bought below VWAP or sold above it, so many of them execute around it. That is why price keeps coming back to this line, and why it often reacts when it gets there.

Think of VWAP like the average price paid for a house on your street this year. If a new listing is priced far above that average, buyers hesitate. If it is priced well below, buyers step in. VWAP is the market's running "neighborhood average" for the day.

How it works

  1. The formula. For each bar, take a typical price (high + low + close, divided by 3) and multiply it by that bar's volume. Add those results up from the open. Divide by total volume from the open. That running result is VWAP.
  2. It resets every day. Standard VWAP starts fresh at the open. Yesterday's VWAP has nothing to do with today's (anchored VWAP is a different tool).
  3. It gets heavier as the day goes on. Early in the session, one big bar can move VWAP a lot. By the afternoon, millions of shares sit behind it, so it barely moves. VWAP is most "alive" in the first hour.
  4. Location tells you bias. Price holding above VWAP means the average buyer today is in profit, and buyers have the edge. Price holding below means the average buyer is underwater and sellers have the edge.
  5. Slope adds context. A rising VWAP with price above it points to a trending day. A flat VWAP with price crossing back and forth points to a balanced, rotational day.
  6. VWAP is a level, not a signal. Crossing VWAP is not a buy or sell by itself. It is a decision point. You still need a reaction, a candle close, volume, and a defined invalidation.

Worked example

Hypothetical stock XYZ, first three 5-minute bars of the day:

  • Bar 1: typical price $100.00, volume 50,000 shares. Price x volume = $5,000,000.
  • Bar 2: typical price $101.00, volume 30,000 shares. Price x volume = $3,030,000.
  • Bar 3: typical price $100.50, volume 20,000 shares. Price x volume = $2,010,000.

Total price x volume = $10,040,000. Total volume = 100,000 shares.

VWAP = $10,040,000 / 100,000 = $100.40.

Compare that to the simple average of the three prices: ($100.00 + $101.00 + $100.50) / 3 = $100.50. VWAP sits lower because the heaviest volume traded at $100.00. Volume pulls VWAP toward where the real business happened.

Now say XYZ trades at $101.20 at 10:00 a.m. It is $0.80 above VWAP. The average buyer so far is in profit, so buyers have the edge. If XYZ pulls back to $100.40 and the 5-minute candle closes back above it on rising volume, that is a reaction at a meaningful level worth studying. If instead it closes below $100.40 and stays there, today's buyers are now underwater and the tone changes.

Notice what we did not do: we did not buy just because price was above the line. VWAP told us where to pay attention.

Common mistakes

  • Treating every VWAP cross as a trade — price crosses VWAP many times on a choppy day and each cross costs you a loss — wait for a close and hold on the new side before acting.
  • Ignoring time of day — early VWAP moves fast and is easily pushed around, while late VWAP is stable — give early crosses less weight until the first 15 to 30 minutes have printed.
  • Using VWAP alone — VWAP means more when it lines up with another level such as the opening range high or yesterday's close — look for confluence before you care.
  • Confusing VWAP with a moving average — a moving average ignores volume and does not reset daily — use the platform's actual VWAP study, set to reset each session.

Checklist

  • Is my VWAP set to reset at the session open?
  • Is price above, below, or chopping around VWAP right now?
  • Is VWAP rising, falling, or flat?
  • Does VWAP line up with another key level?
  • Am I waiting for a candle close before treating VWAP as reclaimed or lost?

Practice: Map VWAP on five sessions

  1. Open the Simulation Lab and load five random sessions with VWAP turned on.
  2. At 10:30 a.m. on each chart, write down whether price is above, below, or chopping around VWAP, and whether VWAP is rising, falling, or flat.
  3. Reveal the rest of the session and note whether the side of VWAP you recorded held into the afternoon.
  4. Log your five observations in the Trade Journal and ask the AI Coach which sessions showed a trend day versus a rotational day.

Key takeaways

  • VWAP is the volume-weighted average price for the session and acts as the day's fair value.
  • Heavy-volume prices pull VWAP toward them, so VWAP shows where real business happened.
  • Holding above VWAP gives buyers the edge; holding below gives sellers the edge.
  • VWAP is a decision level, not an entry signal, so you still need a close, volume and invalidation.

Glossary

  • VWAP — Volume-Weighted Average Price: the average price paid for a stock during the session, weighted by volume at each price, reset each day.
  • Typical price — The bar's high plus low plus close, divided by 3, used as the price input in the VWAP calculation.
  • Fair value — The price where the most business has been done; for the intraday session, VWAP is the common reference.
