How to read NQ key levels before the open

A plain-English guide to the reference levels NQ traders mark before the US open: prior-day highs and lows, overnight range, VWAP, round numbers and calendar risk. Education only.

Most Nasdaq-100 futures (NQ) traders do some version of the same pre-market routine: they mark a handful of price levels on the chart, write a sentence about what they expect, and decide in advance what would prove them wrong. This guide explains which levels people commonly mark, why those levels get attention, and how to read them without turning them into predictions.

This is education only, not financial advice and not a trade recommendation. The numbers in the examples below are illustrative, not current levels. Trading futures involves substantial risk of loss.

What a "key level" actually is

A key level is a price where something measurable happened recently, or where many participants are likely to be looking at the same number. That is all. A level is not a wall, and it does not "hold" or "break" on a schedule. It is a reference point that helps you describe what the market is doing in relation to where it has already been.

Two ideas make levels easier to use:

Levels are zones, not lines. NQ moves in 0.25-point ticks and often probes a few points past a level before reacting. Treat a level as a band of several points.
Levels are context, not signals. A level tells you where a decision might be made. It does not tell you which way the decision will go.

The levels most traders mark first

Here is a typical pre-open checklist for NQ. Each item is something you can read straight off a chart or a data platform.

Level	What it is	Why people watch it
Prior-day high (PDH) and low (PDL)	The extremes of the previous regular session (9:30–16:00 ET)	Yesterday's range is the market's most recent "accepted" area
Prior-day close	Last regular-session price	The gap between it and the open describes overnight sentiment
Overnight high and low (ONH / ONL)	The extremes of the Globex session since the prior close	Shows where overnight traders pushed and where they gave up
London / Asia highs and lows	Sub-ranges of the overnight session	Often the first levels the open interacts with
Session VWAP	Volume-weighted average price for the session	A common "fair value" reference that many platforms plot by default
Round numbers	Multiples of 100 or 500 points, such as 30,000	Psychologically convenient; orders cluster there
Recent swing highs/lows	Pivots from the last several days	Where earlier buyers or sellers were last active
Higher-timeframe averages	For example a 4-hour EMA	Many traders look at the same moving average

An illustration, using made-up numbers: suppose prior-day high is 30,250, prior-day low is 29,980, the prior close is 30,120, the overnight range is 30,060–30,205, and VWAP has not formed yet. In that case the overnight session traded inside yesterday's range, and the nearest reference points above and below the prior close are 30,205 and 30,060. That is a description, not a forecast.

Step 1: build the map from the outside in

Start with the widest levels and work inward. Mark prior-day high and low, then the overnight high and low, then nearby swing points and round numbers, then any moving average you track. Label each level with its source ("PDH", "ONL", "4H EMA") so that at 9:25 ET you are not guessing why a line is on the chart.

Then sort the levels into resistance (above the current price) and support (below it). When several independent levels fall within a few points of each other, that area is often called a confluence zone. More overlap makes a zone more noticeable; it does not make it more reliable.

Step 2: note where price opened relative to yesterday

A simple framing that many traders use is the open location:

Inside yesterday's range: the market is still working within recently accepted prices.
Above yesterday's high or below yesterday's low: the market is trading outside the recent range, which means fewer recent reference points and often faster moves in both directions.
Gap versus close: a large gap from the prior close to the open usually increases volatility in the first minutes.

None of these framings predicts direction. They only show how much room there is before the next reference level.

Step 3: write two scenarios and an invalidation

Instead of predicting, write one sentence for each side. For example: "If price holds above VWAP, the overnight high is the next reference; if it closes back below VWAP, the overnight low comes into play." Then write what would invalidate the idea: a price or condition that tells you your read was wrong and the scenario no longer applies.

Write the invalidation before the open: it is easy to move the goalposts once you have a position or an opinion.

Step 4: check the calendar

Levels behave differently around scheduled data. High-impact US releases such as CPI, jobs and Fed decisions typically land at 8:30 ET or 14:00 ET, and NQ can move several levels in a few seconds, with wider spreads and larger slippage than usual. Before the open, note what is scheduled, when, and whether your own rules say to stand aside. Confirm calendar times yourself; sources differ.

Step 5: remember what levels cannot tell you

They do not predict. A level that reacted yesterday may be ignored today.
They are widely watched, which cuts both ways. Crowded levels can produce sharp reactions and sharp failures.
They age. Overnight levels can be out of date by the 9:30 ET open; the levels in any pre-market note are a snapshot. Our own brief shows the as-of time of its levels for exactly this reason.
They ignore your risk. Where a level sits says nothing about how many contracts you can afford. One full-size NQ contract is $20 per point, so a 25-point move is $500 per contract before costs. Size from the drawdown you can survive, not from how clean a level looks. Our position-sizing guide walks through the arithmetic, including micros.

A repeatable five-minute routine

Mark PDH, PDL, prior close, ONH, ONL and session VWAP once it forms.
Add the nearest swing points and round numbers above and below price.
Note the open location relative to yesterday's range.
Write two scenarios and the invalidation for each.
Check the calendar and your own no-trade rules, then close the notes and let the market show you what it does.

If you want a worked example each trading day without building the map yourself, the free Stacked Edge daily brief publishes NQ reference levels with their as-of date, and states plainly when a level set is incomplete or old. It is a reference sheet for learning, not a set of instructions to trade. Paid plans are not open yet; the waitlist is the only thing to join.
