Anchored VWAP is just VWAP started from a point you choose instead of the session open. Anchor it to the day's low and it plots the volume-weighted average price of everyone who has bought since the bottom — a rising line that acts as dynamic support for the move off the low.

Why the day-low anchor matters

Traders who bought the bounce are, on average, in at the anchored VWAP. As long as price holds above it, those buyers are collectively in profit and inclined to defend — so pullbacks to the line tend to find support. Lose it, and the average bounce-buyer is now offside, which often accelerates a reversal. The line is a live read on whether the move off the low is still healthy.

How to use it on a scalp

Treat the day-low anchored VWAP as a trailing support level in an uptrend off the bottom: buy pullbacks that hold it (a rejection off the line), target the next level up, and use a decisive break below it as your invalidation. It's especially useful after a stop-run reversal or a bounce off the put wall, giving the new uptrend a moving line to lean on.

The day-low anchored VWAP is the bounce-buyers' cost basis. Above it, they defend; below it, they bail — a support line with a reason.

The honest caveat

Anchored VWAP is a context tool, not a signal — it confirms structure, it doesn't predict. It's strongest when it lines up with a mapped dealer level (the put wall, gravity), and weakest as a standalone line in choppy tape. Use it to frame where support should be and let price confirm; don't buy the line blindly. Pair it with the session VWAP for the full picture.
