VWAP reversion and trend

Volume-weighted average price is the session's average trade price, weighted by how much volume printed at each price. Day traders use it two ways. One fades an extended move back toward VWAP. The other only takes trades in the direction of a sloping VWAP, treating it as the session's fair price.

Not investment advice. Nothing here is a recommendation to buy or sell anything. Backtests and historical studies are not guarantees, and a rule that worked in one sample can fail in the next. Trading can lose money. Links are for education, not endorsements. Do your own research.

Rules

VWAP resets at the session open. A fade buys a stretch below VWAP, often beyond a standard-deviation band, with a target at VWAP and a stop beyond the extension. A trend rule does the opposite: buy pullbacks while price and VWAP are both rising, and avoid longs while price is pinned below a falling VWAP. Institutions also use VWAP as an execution benchmark, which is why the level attracts orders.

Where AI fits

AI helps most on the execution side, slicing an order so the average fill stays near VWAP, and on labeling whether a day is a fade day or a trend day before the entry rule is armed. An LLM can build the session-anchored calculation and a research notebook. It should not be asked to guess the next print from a screenshot.

Markets

Stocks, stock-index futures, and other intraday markets with real volume. FX VWAP depends on the feed, because spot FX has no single consolidated tape.

Timeframes

Intraday, from 1-minute to 15-minute, anchored to the cash or futures session. A multi-day anchored VWAP is a separate tool.

Risks

A fade into a trend day keeps extending. A trend entry into a choppy open gets chopped up. VWAP is not defined the same way on every platform, and a bad volume feed makes the line meaningless.
