What stop works for a VWAP reversion trade?

Just beyond the extreme of the move, so that a new low proves the reversal wrong. Moving it further away only turns a small loss into a larger one on a trend day.

When in the day does VWAP reversion work best?

Often in the late morning and early afternoon, when the opening rush has passed and many days settle into a range. In the first half hour, VWAP itself is still moving fast.

Can I combine VWAP reversion with VWAP bands?

Yes. Standard deviation bands around VWAP give a consistent way to define a stretch, for example a touch of the second band, instead of a fixed percentage.

How far from VWAP is far enough?

There is no fixed number. Traders use a percentage, such as 1.5% for a large stock, or bands of 2 standard deviations around VWAP. Whatever you choose, fix it before testing.

Is this the same as the VWAP pullback?

No, it is the opposite. The pullback joins a trend when price returns to VWAP; reversion bets that price returns to VWAP from far away.

Why does price return to VWAP?

Often it does not. On range days it tends to; on trend days it stays away all day.

VWAP mean reversion strategy: rules and example

The idea

VWAP, the day's volume-weighted average price, works like a centre of gravity for the session. When price runs far away from it without news, the move often stalls and drifts back.

VWAP reversion waits for a big stretch, for example price more than one and a half percent under VWAP, then for the selling to stall, and buys with VWAP itself as the target.

Step by step

The rules

Setup

Price is far from VWAP (for example more than 1.5% below) after a fast move, without major news.

Entry

Wait for the move to stall, then buy when a candle closes higher than the one before.

Stop-loss

Under the low of the move.

Target

VWAP.

Filters that help

Avoid it on news days and on trending days where price never returns to VWAP.
Some traders use VWAP standard deviation bands to define 'far'.

Why it can work

Large players measure their fills against VWAP. Far below it, buying looks cheap to them and selling looks expensive, which tends to slow the move. Short-term traders who drove the stretch also take profit, adding to the snap back.

Short-term traders who drove the stretch also need to take profit, and many of them use VWAP as their target too, which can pull price back toward it. On range days, those forces tend to win; on trend days, new buyers or sellers keep arriving and VWAP is left behind.

Worked example

A stock slides to $39.35, about 2% under VWAP at $40.10, then stalls. A candle closes higher at $39.62: buy, with the stop under the low at $39.29.

VWAP, the target, is 48 cents above the entry, about 1.5R for a 33-cent stop. Risking $100 that is 303 shares.

When it works, when it fails

Works best

On quiet, range-bound days in liquid stocks and index futures.

Struggles

On trend days, when price moves away from VWAP and keeps going. It is the direct opposite of the VWAP pullback trade, which works on exactly those days.

Common mistakes

Fading strong moves driven by news.
Entering before the move stalls.
Holding for more than VWAP: the target is the average, not the other side.

What the evidence says

Popular, untested

Widely used, but no rigorous public testing. An idea to test yourself.

VWAP is a real institutional benchmark, and stretched intraday moves often retrace. There is no rigorous public study of this reversion rule after costs, and it fails badly on trend days, which are hard to spot early.

Test it on your own records, and keep the costs of frequent intraday trading in mind.
