# VWAP and Anchored VWAP in Practice VWAP is the average price everyone paid since a starting point, weighted by how much they traded, and it is one of the simplest ways to tell whether buyers or sellers are in control of a session. ## What VWAP actually measures Every trade has a price and a size. Multiply them, add them all up since the start of the session, and divide by the total volume. That is VWAP. A trade of 50 BTC moves it much more than a trade of 0.1 BTC, which is the whole point: it reflects where the real money changed hands, not just where price happened to tick. Because it resets each session, VWAP starts the day sitting on price and then lags behind it. In Market Open the VWAP indicator resets every day at 00:00 UTC, whatever timezone your chart shows. ## VWAP as fair value The useful mental model is this: VWAP is the price at which the average participant today is flat. If BTC is trading at 101,200 and session VWAP is 100,400, the average buyer today is in profit and the average seller is under water. Buyers have been winning. Below VWAP, the reverse. That is why price often reacts near it. Longs who bought earlier defend it, because a drop through it puts the average long in the red. Shorts treat a rally back to it as a second chance to sell at fair value. Neither group is guaranteed to win, but both are paying attention. ## Mean reversion days and trend days The same line behaves very differently on two kinds of days, and the first job is to figure out which kind you are in. On a **rotation day**, VWAP is nearly flat and price crosses it again and again. Stretches far above it get sold back toward it, and dips far below get bought. On those days, fading moves away from VWAP and targeting a return to it is the natural trade. On a **trend day**, price leaves VWAP early and stays on one side. VWAP itself starts to slope. Pullbacks reach toward it and bounce without closing through. Fading on a day like that is how people get run over, because the stretch keeps getting stretchier. A few clues help you tell them apart: - How many times price has crossed VWAP in the first few hours. Many crosses lean rotation; none leans trend. - The slope of the line. Flat is balance. Steady slope is one side in charge. - How pullbacks behave. Bounces right off VWAP lean trend; slicing through it leans rotation. None of these is certain by midday, and some days switch from one type to the other after news. Stay flexible. ## Anchored VWAP Session VWAP answers "who is winning today." Anchored VWAP answers "who is winning since this specific moment." In Market Open you have two ways to anchor: the **Anchored VWAP** drawing tool (under Volume-Based drawings) starts the calculation at any candle you click, and the **Anchored VWAP** indicator adds lines that start at each Daily, Weekly, Monthly, Quarterly or Yearly UTC open, with optional ±σ bands. Good places to anchor: - **A major swing low or high.** Anchor at the low that started an uptrend. As long as price holds above that line, the buyers since the low are, on average, in profit. - **An event.** Anchor on the candle of a big macro release or, for a stock perp, on an earnings reaction. Say the NVDA perp gapped from 175 to 188 after earnings. An anchored VWAP from that candle shows the average cost of everyone who traded the reaction. A slow drift back to it is a test of whether those buyers still believe. - **A breakout candle.** Anchor where price left a range. If price falls back below that line, the breakout traders as a group are losing, and pressure to exit can build. Do not anchor everywhere. Two or three lines from moments that genuinely mattered beat ten lines from random candles. ## Honest limits VWAP is an average. It describes the past and has no idea about the next candle. On thin markets a few large prints can drag it around. It also tells you nothing about why price is where it is. Combine it with levels you already trust, or with a Fixed Range Volume Profile drawn over the same move, so you can see where volume clustered as well as where the average sits. ## Try it on Market Open 1. Open BTC on the 5m chart, add VWAP and count how many times price crosses it before the middle of the UTC day. 2. Pick the Anchored VWAP drawing tool and click the most recent major swing low. Note where price sits relative to it. 3. Set a crossing alert on VWAP so you are told when price comes back to it. Alerts only fire while Market Open stays open in your browser. 4. Use Bar Replay on a few past sessions and label each one rotation or trend before you play it through. _Educational content, not investment advice. Leveraged trading can lose more than your margin._
