Reading VWAP

In Lesson 6 you learned how VWAP is calculated. This lesson is about how traders describe price using it. Everything here is vocabulary for reading a chart. None of it is a rule for when to trade.

Above or below

The simplest reading is where price sits compared with the line.

• Price above VWAP: the market is trading higher than the volume-weighted average price paid since the anchor. Anyone who traded at “the average” so far is looking at a higher price now.
• Price below VWAP: the market is trading lower than that average.
• Price on both sides: price keeps crossing back and forth over a fairly flat VWAP.

TradingView’s help page connects these to Lesson 1’s vocabulary: prices staying above VWAP are associated with a rising market, prices staying below with a falling market, and prices on both sides with a sideways market. Schwab’s article adds that the slope of VWAP is worth noticing: a rising line reflects prices that have been trending up, and a falling line the opposite.

Keep the logic straight, though. Price is above VWAP because it has been rising. Being above VWAP does not cause it to keep rising. It is a description of what already happened.

“Fair value”

You will often hear VWAP called fair value. Schwab’s article explains the idea: some traders view VWAP as a rough guide to the price buyers and sellers have agreed is fair at that point in the session, since it is literally where the volume traded on average.

That is a useful way to think about it, with one warning: “fair” here is a nickname, not a promise. Nothing pulls price back to VWAP. The market can trade far away from it all day.

Standard deviation bands

Many platforms can draw extra lines above and below VWAP called standard deviation bands. Both TradingView and Schwab’s thinkorswim platform offer them.

What standard deviation means

Standard deviation is a measure of spread: how far, typically, values sit from their average.

• If prices have stayed close to VWAP all session, the standard deviation is small.
• If prices have swung far above and below VWAP, the standard deviation is large.

A band is drawn at VWAP plus or minus a multiplier times that standard deviation. For example, a “1” band sits one standard deviation from VWAP, and a “2” band sits twice as far. You choose the multipliers in the indicator settings; TradingView lets you set up to three pairs. The exact calculation details differ a little from one platform to another, so read your platform’s help page.

Reading the bands

Because the bands are built from spread, their width tells you something:

• Narrow bands: the session’s prices have stayed close to VWAP.
• Wide or widening bands: prices have been spreading out further from the average.

And price’s position tells you how far it is from the average in terms of the session’s own spread. “Price is near the upper 2 band” means price is unusually far above VWAP compared with how spread out prices have been today.

You will see articles describe the outer bands as “overbought” or “oversold” levels. Schwab mentions that view. Treat those words as opinions some traders hold, not facts about the market. Price can ride along a band, or go past it, for a long time.

Putting it into words

Here is how you might describe a chart using only this lesson’s vocabulary (example, not a real session):

“Price opened below VWAP, crossed above it in the first hour, and has stayed above a rising VWAP since. The bands have widened through the morning, and price is now between the upper 1 and upper 2 bands.”

That sentence contains no prediction and no instruction. It is a clear, shareable description of the session so far, which is exactly the skill this level is building.

Key ideas

• Above VWAP means price is higher than the session’s volume-weighted average so far; below means lower. These describe the past, not the future.
• The slope of VWAP reflects whether prices have been rising or falling.
• “Fair value” is a nickname for VWAP, not a promise that price will return to it.
• Standard deviation bands show how spread out prices have been around VWAP; wider bands mean more spread.
• VWAP and its bands are never a signal by themselves.
