Fixed Range vs Session Volume Profile: When to Use Each

A session profile answers “where did this day’s auction do business?”. A fixed range profile answers “where did this particular move do business?”. Choosing between them starts with the question, not the tool.

Key takeaways

A session volume profile covers one trading session with fixed start and end times, so its POC, VAH and VAL are comparable from one day to the next.
A fixed range volume profile covers a stretch you choose, such as a trend leg, a balance area or the move since a news release, and can span several sessions or part of one.
Session profiles depend on the session definition: including overnight trade or not can change every level.
Fixed ranges depend on the anchors: redrawing them until the levels fit the chart is hindsight, not analysis.

Fixed range vs session volume profile in one paragraph

Choosing a fixed range vs session volume profile is choosing a time window. A session profile resets at the start of every trading session and runs to its end, giving one distribution per day. A fixed range profile, sometimes called an anchored or range profile, covers whatever stretch of bars you select between a start point and an end point. The calculation is the same; the window decides what the POC and the value area describe.

The wider family of profiles, including composite and visible-range versions, is introduced in the volume profile guide. This comparison focuses on the two windows traders switch between most often during preparation, and on the errors each one invites.

How a session profile works

A session profile follows the trading hours defined by your platform’s session template. On equity index futures, which trade nearly around the clock, there are two common choices: the full electronic session, overnight included, or only the regular trading hours that match the cash market. They give different distributions, because overnight trade is often thinner and covers different prices.

The strength of a session profile is regularity. Every day is measured with the same ruler, so the prior POC, VAH and VAL can be compared with the current ones, and the prior session’s levels are known before the open. That makes them natural reference points, and the developing levels show how value forms during the day.

Its weakness is that the market ignores the clock. A move that starts in the afternoon and continues the next morning is split between two profiles, and neither shows it as a whole. A session with two distinct phases, a quiet morning and an afternoon trend, is also blended into a single distribution.

How a fixed range profile works

A fixed range profile is drawn between two points you choose. In NinjaTrader 8, the drawing tool version of the Order Flow Volume Profile, one of the platform’s Order Flow+ tools, is placed with one click at the start and one at the end, and those two points define the bars it covers. Other platforms offer the same idea under names such as fixed range or range volume profile.

The window can be anything: a single trend leg from swing low to swing high, a balance area that lasted several days, the move since a central bank statement, or the overnight session on its own. The profile then shows where business concentrated within that event, which a session profile would have mixed with unrelated trade.

The weakness mirrors the strength. Because you choose the anchors, two traders can draw two different profiles on the same chart, and one trader can redraw the range until its levels line up neatly with past turning points. Anchors need a rule written in advance, such as the swing that started the move or the time of the news, so that the profile describes the market rather than your expectations.

Fixed range vs session profile side by side

The table compares the two windows on the points that matter when you use them as references.

Session and fixed range volume profiles compared.
	Session volume profile	Fixed range volume profile
Window	One session, fixed start and end times	Any stretch of bars between two chosen points
Reset	Automatic, at each new session	None, unless you redraw it
Question answered	Where did this session’s auction do business?	Where did this specific move or balance do business?
Comparability	High: every day follows the same rule	Low, unless the anchors follow a written rule
Main setting risk	Electronic session versus regular hours	Choice of start and end point
Typical references	Prior POC, VAH and VAL, developing POC	POC of a trend leg, nodes inside a balance area

Neither column is better in general. Each answers a different question, and many traders keep both on the chart in different colours.

When to use each

A simple way to decide is to name the event you want to measure. If the event is a day, use the session. If it is a move, a range or a reaction that ignores the clock, use a fixed range. Nodes inside a fixed range are read like on any other profile; the comparison of high volume nodes and low volume nodes explains how.

Preparing the next session: the prior session profile gives fixed, comparable references that are known before the open.
Following the current day: the developing session profile shows whether value is building higher, lower or in place.
Studying a trend leg: a fixed range from the start of the leg to its end shows where the move paused and traded heavily, areas often watched on a pullback.
Mapping a balance area that spans several days: a fixed range over the whole balance shows its POC and edges better than several separate sessions.
Reviewing a news reaction: a fixed range from the release to the point where trading calmed down isolates the volume the event produced.

The VWAP parallel: session and anchored

The same choice exists for the volume-weighted average price. A session VWAP resets each session and gives a daily reference; an anchored VWAP starts at a chosen event and never resets. TEVO VWAP, the free NinjaTrader 8 indicator on this site, offers session, weekly, monthly and anchored modes, each with three volume-weighted standard deviation bands.

Pairing the windows keeps the logic consistent: a session profile with a session VWAP for the day’s auction, a fixed range profile with a VWAP anchored at the same starting point for a specific move. The profile shows where volume concentrated; the VWAP shows the average price paid along the way. TEVO VWAP does not draw a volume profile, so the profile itself has to come from another tool.

Common mistakes with both windows

Mixing session definitions, for example comparing a regular-hours VAH with an electronic-session POC.
Anchor shopping: moving the start or the end of a fixed range until its POC matches a level you already liked.
Forgetting to extend the end point: a fixed range that stopped yesterday says nothing about today’s trade.
Reading a short fixed range as if it were a session: a range of a few bars holds little volume, and one large trade can decide its POC.
Treating any profile level as a barrier. Levels from either window are references for reading behaviour; the guide to POC, VAH and VAL explains what they measure and what they do not.

Put it into practice

Frequently asked questions

Is a fixed range volume profile the same as a composite profile?

Close, but not quite. A composite usually merges several whole sessions, for example the last few days or weeks. A fixed range is defined by any start and end point you choose, including part of a session or a stretch that crosses sessions.

Should a session profile include overnight trading?

It depends on what you want to measure. The full electronic session shows all trade in the contract; regular trading hours focus on the period when the cash market is open, usually the busiest. Pick one, label it and keep it constant.

How do I choose the anchors of a fixed range?

Use a rule you can apply before seeing the result: the swing that started a move, the time of a news release, or the first and last bar of a balance area. Avoid adjusting the anchors to make the levels fit past price action.

Does TEVO VWAP draw a volume profile?

No. TEVO VWAP draws the volume-weighted average price with standard deviation bands for the session, week, month or an anchor. It complements a profile but does not replace one.
