High & Low Volume Nodes (HVN/LVN)

From 09:45 ET (21:45 ICT, winter), NQ grinds sideways for 40 minutes inside a 15-point band. Then, at 10:31 ET, it crosses the next 15 points in six minutes. Same instrument, same morning, two very different speeds.

Yesterday’s volume profile already showed both zones: a fat block of volume where price ground, a thin valley where it moved. This lesson teaches you to find those zones, what they record, and what one large NQ study says about using them. (The morning is a synthetic illustration, not a real date.)

Key terms

High Volume Node (nút khối lượng cao, HVN): a price area on a profile where much more volume traded than at the prices around it. Both sides did business there; the auction accepted those prices Definition.

Low Volume Node (nút khối lượng thấp, LVN): a price area where much less volume traded than around it, usually a valley between two HVNs. The auction passed through quickly or refused to stay Definition.

Both are relative: a node is high or low compared with its neighbours on the same profile. Zoom out to a composite (M2.04) and the picture can change.

Chart first: two peaks and a valley

What to see: the profile is a record of where volume traded, not a map of where price goes next. The value area here (25,030–25,080, built by the two-row method from M2.02) spans both peaks and the valley, so “inside value” does not mean “inside a fat node”.

How it works

What a node records

Volume at a price is the sum of every trade there, buyers and sellers together. A fat node means the auction spent time and contracts at those prices: two-sided business, agreement on value. A thin node means the auction did not: it moved through on little volume, or never came back to trade there.

From that record comes one forward-looking idea: when price returns, it tends to move faster through the thin area than through the fat one PlausibleOne trader's study. The mechanism is plain: fewer resting orders and fewer traders with a reason to defend those prices. The evidence is weak, though (see “What the data says”): one practitioner’s NQ study found a lean in that direction that did not survive its own correction for testing many claims.

Three refinements:

• An LVN being crossed is a description: price is moving where the auction did not agree before. If price instead stalls inside an LVN and starts building volume, the LVN is turning into an HVN: value is being established where none existed Definition.
• Several HVNs in one profile mean several accepted prices: a market still negotiating, as on many balance days (M1.02).
• Nodes describe; they do not signal. An HVN does not say “buy here”, or which side wins the next negotiation there. It says “the auction agreed here before; watch what it does now.”

Myth / hypothesis: “HVNs act as magnets, and as support and resistance: price is drawn back to them and stalls there because both sides hold positions from that price.” Lore On NQ, a large practitioner test found no edge for the magnet idea (details below). “Both sides have inventory to defend” is a reasonable story, not a measurement: volume at a price includes positions opened and closed there.

Two LVN rules that sound opposite

You will hear two pieces of practitioner folklore about LVNs, often from the same person:

• “LVNs get rejected.” Price reaches the thin area at the edge of an HVN, fails to push in, and snaps back.
• “Price runs through LVNs.” Once inside the thin area, price crosses it quickly to the next HVN.

Put together they become one rule, and that rule was tested:

Myth / hypothesis: “At an LVN edge, price either rejects or runs to the next HVN, so you can trade the exit.” Lore Unresolved on NQ (−0.3 percentage points, 95% CI −5.0 to +4.4, n = 863). You cannot know in advance which exit price takes, and the test did not show that either exit comes faster or more often than at comparable prices.

What you can do is plan both exits before price arrives, with an invalidation price for each. Footprint reads at the edge (M3.02 absorption, M3.04 delta) describe what is happening as it happens; they are not tested forecasts of the exit either.

How to find nodes without fooling yourself

Nodes depend on your settings. With a very fine row size (one tick per row), a quiet profile looks jagged and every small dip looks like an LVN. With a coarse row size, real LVNs get smeared away.

• Use a row size that makes the profile’s shape readable: for NQ a daily profile at a few points per row is a common start. Experiment once, then keep it fixed, and quote node prices with their row size.
• Look for LVNs between two clear HVNs: a valley between two peaks. A thin area at the very top or bottom of the profile is usually the day’s extreme, read as a tail or a poor high/low instead (M2.09).
• Check big nodes on a second lookback (today’s profile and a 5-day composite). Nodes also age: an HVN from one quiet day weeks ago records less than one from yesterday’s full session.

Why it is still worth knowing

Even with one weak lean and two nulls, nodes earn their place. They give you shared vocabulary for describing the auction (“price is back in yesterday’s HVN”). They tell you where your stop sits in thin air and where it sits inside a crowded price. And they are a hypothesis you can test yourself: log every LVN entry for a month and count how fast price leaves, and which way.

What the data says

The reject-or-run rule (myth box above) came out inconclusive in the same study, leaning very slightly against the rule, with an interval too wide to tell.

Worked example: long side through an LVN (synthetic)

Use the profile above as yesterday’s session: lower HVN 25,040–25,055 (POC 25,050), LVN 25,060–25,075, upper HVN 25,080–25,090.

Today price rallies from 25,020. From 09:45 ET it rotates for 40 minutes between 25,040 and 25,055: both sides active, each push above 25,055 sold back. A trader who buys inside that HVN expecting a quick move pays for two-sided chop and has no clean place to be wrong.

The trader who waits writes the plan first:

• If price holds above 25,056 for two 5-minute closes and buyers are lifting offers in the footprint, then buy 1 MNQ at 25,057.00.
• Invalid back below 25,047.00 (back inside yesterday’s accepted prices): 10 points, 40 ticks, $20 on 1 MNQ ($200 on 1 NQ).
• Target 25,079.00, just under the upper HVN: 22 points, $44 on 1 MNQ. The target sits where the trade stops being in thin air; it is a planning choice House rule, not a forecast that price gets there.

At 10:31 ET (22:31 ICT) the condition triggers, and price crosses 25,060–25,075 in six minutes. This time the lean showed up. On the study’s numbers it is weak, so expect many days where it does not.

The mirror and the failure

ES, synthetic: HVN 5,960–5,972, LVN 5,975–5,980, HVN 5,983–5,995. Price rallies from the lower HVN into 5,976. The footprint at 5,976–5,977 shows heavy buying at the offer but no progress; delta on the next two bars turns negative, and within ten minutes price is back at 5,968.

The trader who bought 5,976 “because LVNs are fast” assumed the exit. Price left the LVN quickly, but out the bottom. The mirror plan was available in advance: if price enters the LVN and closes back below 5,974, then a short toward the lower HVN; invalid above 5,981. Neither plan needed a forecast of the exit, only a written condition for each door and a price where it is wrong.

Common mistake: Treating a profile feature as an edge. That price spent time at an HVN is true by construction; that it will come back, or stop there, was tested on NQ and showed no edge. Read nodes as a map of where the auction agreed, and put the forecast in a written if-then plan with an invalidation price.

Recap

• HVN: a price the auction accepted (heavy volume). LVN: a price it passed through or refused (light volume). Both are relative to their neighbours and depend on row size and lookback.
• Faster travel through LVNs than HVNs is a weak lean from one trader’s NQ study (Plausible). HVNs pulling price back and the reject-or-run rule at LVN edges showed no edge (Lore).
• Find LVNs as valleys between two peaks, fix your row size, and check big nodes on a second lookback.
• At an LVN, write both exits and an invalidation price before price arrives.
