VWAP explained: the line that resets every morning

VWAP is the line day traders watch on intraday charts. It's an average price, but with a twist: busy moments count more than quiet ones. And it starts fresh every session.

What VWAP is

VWAP stands for Volume-Weighted Average Price.

It's the average price of the day so far, where each price counts by how much traded there. A price where 1 million shares changed hands counts far more than a price where only 100 did.

So VWAP answers one question: what's the average price people have actually paid today?

How it's worked out (a simple example)

Say only two trades happen this morning:

• 100 shares trade at $10. That's $1,000 worth.
• 300 shares trade at $11. That's $3,300 worth.

Add the money: $1,000 + $3,300 = $4,300.

Add the shares: 100 + 300 = 400.

Divide: $4,300 ÷ 400 = $10.75.

A plain average of $10 and $11 would be $10.50. VWAP is higher, because more shares traded at $11. The busy price pulls the line toward it.

On a real chart, the same thing happens candle by candle. Each candle adds its price × its Volume to a running total. Charting apps usually use the candle's "typical price" (high + low + close, divided by 3) for each candle.

Why it resets every session

VWAP starts again at the beginning of each trading session. For US stocks, that's the start of the trading day.

That's why it's mostly an intraday tool. On a 5-minute chart you'll see it begin fresh each morning, then wander through the day.

On TradingView, the VWAP indicator has an "anchor period" setting. Its default is Session, which gives the classic reset. Settings like extended hours can change where a session starts, so check yours.

There's also anchored VWAP: the same math, but it starts from a point you pick, like a big turning point. It doesn't reset.

Why traders watch it

• A fair-price yardstick. Big funds often judge their own buying against VWAP. Buying below it means they paid less than the day's average.
• Above or below. Price above VWAP means today's buyers have, on average, paid less than the current price. Below means the reverse. Many day traders use this as a quick read of the day so far.
• An area to watch. On some days, price pulls back to VWAP and turns. On others it slices straight through.

What VWAP can't do

Here's the honest part.

• It can't predict. It's an average of what already traded.
• It lags more as the day goes on. Early in the session, a few candles move it a lot. By the afternoon, hours of trading are in the average, so it barely moves.
• It's weak on choppy days. When price chops back and forth across the line, each cross looks like a signal and most go nowhere.
• Volume data varies by market. Stocks and futures trade on exchanges with real volume. Spot forex has no single central exchange, so the volume your chart shows comes from a data provider and may not match the whole market. That makes VWAP on forex charts a rougher guide.
• It means little on daily charts. It's built for the session. A one-day "average" on a daily chart is just one dot.

Where it fits with our method

We read the chart's turning points first: the last places price turned around.

On an intraday chart, look at those turning points before you look at VWAP. Is the day making higher highs and higher lows? Lower ones? Neither?

Then VWAP can act as a second opinion:

• The turning points say "up", and price holds above VWAP. They agree.
• The turning points say "up", but price keeps failing at VWAP. That's a reason to be more careful, and to wait for price to show you.

Also check the bigger chart first. A morning above VWAP doesn't change a daily downtrend. See multiple timeframe analysis.

One clean read beats six indicators.

Common mistakes

• Buying every touch of VWAP. Some days it holds. Some days price goes straight through. The touch alone isn't a reason.
• Reading it in the first few minutes. With so little data, the line jumps around a lot early on.
• Using it on daily or weekly charts. It's a session tool. Use it on intraday charts.
• Trusting forex VWAP like stock VWAP. The volume behind it is less complete.
• Treating "above VWAP" as a buy signal. It describes the day so far. The decision still comes from the chart and your plan.

Try it today on TradingView

About 15 minutes, on a weekday chart of a big US stock or index fund.

1. Open a 5-minute chart. Add "VWAP" from Indicators (anchor: Session).
2. Scroll back a few days. Notice where the line starts fresh each session.
3. Pick one day. Before looking at VWAP, mark the day's turning points. Up, down or sideways?
4. Now look at VWAP. How many times did price cross it? Did it act as a floor, a ceiling, or neither?
5. Repeat on a choppy day. Count the crosses. That's the false-signal problem, in your own eyes.
