VWAP trading: what the line is good for in futures day trading

VWAP trading doesn't mean buying at a line. VWAP tells you where the market has traded on average since a fixed starting point. That answers two questions: what kind of day is this, and is price expensive or cheap right now? For those two questions it is very good in futures day trading.

It won't tell you what happens next. And in some situations it is useless, which I cover further down.

Risk Warning: Trading futures and other financial instruments carries significant risk of loss. Past performance is not indicative of future results. Only trade with capital you can afford to lose.

What the line shows you

VWAP is the average price weighted by volume. That's all you need from the formula. Most explanations of the VWAP indicator stop there.

Read it like a price tag. When price is above VWAP, the market is trading more expensive than its average since the start. Below VWAP it's trading cheaper. That is the meaning of VWAP.

It started out as a yardstick for execution. Large investors use it to measure how well an order was worked. As an institutional trader I was evaluated against the Volume Profile myself. The execution algorithms I operated were mostly VWAP-based. They measured themselves against their own VWAP, calculated from when they started, never against a daily or session VWAP.

So the line on your chart isn't even the one an algo like that measures itself against. You can't conclude from it that someone is going to buy there for you.

What VWAP is good for in futures day trading

It's good for context. You can read four things from it, and the first one matters most.

What kind of day it is

Look at the slope. If VWAP runs flat and price keeps crossing it in both directions, you have a two-way market and neither side is getting through. If it slopes clearly and price stays on one side, you have a one-way market. You'll find how to classify that early in the day under market phases.

Everything else depends on this question. The same test of the line means something different on a range day than on a trend day.

Which direction you think in

Above the line you lean toward longs, below it toward shorts. That is a lean and not a trade signal. It only holds close to the line. Right on the line the market has no clear direction for me. I don't form an opinion there. I step back and only count the side once price is clearly above or below. Whether you can trade there is a different question.

That's a paradox. Above VWAP a seller is mathematically getting the better price. But when price has only just flipped above the line, momentum wins at first, because everyone still tries to squeeze out a slightly better deal. So this holds at the start of the flip and not late in it.

How expensive price is right now

Distance from the line tells you more than the side does. If you use the line as the reference for your stop, your risk grows with every point of distance. With the same target your risk-reward gets worse. And far from the line the edge is gone for me anyway, because mean-reversion funds and market makers lean against the move there. If you keep chasing out there, you get stopped out again and again.

Where it's worth taking a closer look

The line shows you a location. What happens there shows up in the order flow. If sellers get absorbed at VWAP or Big Trades show up there, that counts.

When VWAP is useless

On a trend day this becomes a problem. If you trade VWAP reversion, you expect price to come back to the line, and on range days it often does. But price and the line can meet again in two ways: price runs to the line, or the line runs to price. On a trend day it can be the second. Or the distance simply stays, and you end up waiting for a return that doesn't come.

You don't have the volume problem in the Nasdaq future NQ. The contract trades on a single exchange, CME, so there is central volume.

The starting point decides which line you see

A VWAP is always an average from a specific moment on. That matters in futures because NQ trades nearly around the clock. By the New York cash open it has already traded for hours, and if your session includes the overnight, all of that is in the daily VWAP.

That's why I use up to three VWAPs in NQ: daily, EU session and US session. The daily is always on my chart, the session VWAPs only sometimes. When the chart gets too busy, I switch them off. Nobody knows in advance which line will be the best one today, so I'd rather keep it simple. Early in the US session the US VWAP often matters more, because it only measures what happens from the cash open on. Later the two usually run almost parallel. And all of them are rough areas, price doesn't react to the exact tick. If price turns for no obvious reason just short of the daily VWAP, switch on the US VWAP, and the explanation is often there. How I read NQ otherwise is in my guide to Nasdaq futures.

The calculation differs too. TradingView calculates by default with each bar's typical price, the average of high, low and close. That is an approximation, and the line can differ from one calculated from individual trades. For preparation it's enough.

What the bands tell you

Standard deviation bands around VWAP show how far price has moved relative to the variation so far. That lets you compare distance on a quiet day and on a wild one.

You'll often read that 68 percent of prices sit inside the first band and 95 percent inside the second. That only holds for normally distributed data, and you can't count on that intraday. On a trend day price can run along the outer band for a long time. So a band is not a price where the market has to turn.

With an anchored VWAP you choose the starting point

An anchored VWAP calculates from a point you set yourself, such as a significant high or low or the start of a big move. That asks a different question: where is the average price of all trades since that event?

The difficulty is that you don't know when an institution started. Unusual volume, a very large trade or the start of a campaign are educated guesses for me. If you're slightly off, the average is still usable. The longer someone executes, the less a small miss matters. In hindsight, though, you can always find an anchor where price turned nicely. So it only tells you something if you set it beforehand, for a reason you can name.

Where to start

Use VWAP first for one single question: what kind of day is this? Only once you've answered that do you look at side and distance. The order flow decides whether you trade at the line.

Your style decides it too. As a scalper you take every real opportunity, as a day trader you wait for the bigger move. Neither one makes more money by nature. But a day trader who takes every scalp around the line will likely lose money.
