A volume profile answers one question: at which prices did business actually get done?
Your normal chart plots volume against time — bars along the bottom. A volume profile plots it against price — a histogram down the side. That single change turns volume from a rhythm into a map.
Everything in the previous nine lessons needed "a level that matters". This is where those levels come from.
01 — The anatomy
Reading a profile
The fat middle is where the market spent its time and agreed on price. The thin edges are where it went, found no interest, and left.
Four terms cover almost everything you need:
- POC (Point of Control) — the single price with the most traded volume. The fairest price of the session by the market's own vote.
- Value Area — the price range containing roughly 70% of the session's volume, built outward from the POC. Its boundaries are VAH (value area high) and VAL (value area low).
- HVN (High Volume Node) — any price that traded unusually heavy volume. Areas of agreement.
- LVN (Low Volume Node) — any price that traded unusually light volume. Areas of disagreement, where price moved through quickly.
A single print is the extreme version of an LVN — a price level that traded so little it appears as a single tick-wide sliver. It marks a place the market rejected almost instantly.
02 — Why it works
What price does around these areas
These are tendencies, not rules. They exist because of how participants behave, not because of magic.
High volume areas
Lots of contracts changed hands here, so lots of participants have positions and reference prices here. Price tends to slow down, chop and rotate when it returns — there is two-sided interest. HVNs and the POC often act as magnets.
Low volume areas
Almost nobody transacted here, so there is little resting interest and few positions to defend. Price tends to move through quickly in either direction. LVNs are where fast moves happen and where they often start from.
The practical consequence: LVNs make better decision points than HVNs. If you are wrong at an LVN, price usually tells you quickly, because there is nothing there to hold it. If you are wrong in the middle of an HVN, you can sit in chop for an hour finding out.
03 — Which profile
The profiles worth having on your chart
You do not need all of these every day. You do need to know which one you are looking at and why.
The core idea
The developing POC is the most under-used tool here. A POC that keeps migrating higher through the session means value is being accepted higher — buyers are not just pushing price, they are getting the market to agree at those prices. That is a meaningfully different market than one where price rises but the POC stays pinned at the open.
04 — The method
Level, then reaction, then confirmation
This is the sequence that connects everything in this course, and it is the thing that separates using profiles well from using them badly.
Common mistake
Buying VAL because it is VAL. Selling the POC because it is the POC.
A level is a place to pay attention, not a reason to enter. Levels fail constantly — that is what a trending day is. Without a reaction and without order flow evidence that someone is actually defending the level, you are just placing orders on a line someone drew.
05 — Honest limits
What volume profile does not tell you
Worth knowing
- It is entirely backward-looking. It describes where business was done, not where it will be done.
- It has no timing. A level can be tested in five minutes or five days. Profiles say nothing about when.
- Settings change the picture. Value area percentage, session boundaries and tick grouping all shift where your lines land. Two traders can have genuinely different VALs for the same day.
- Levels degrade. Yesterday's POC matters more than the POC from three weeks ago. Relevance decays, and there is no formula for it.
Key takeaways
- A volume profile plots volume by price, showing where the market actually did business.
- POC is the highest-volume price; the value area holds ~70% of volume between VAH and VAL.
- HVNs attract and slow price. LVNs and single prints see fast movement and make cleaner decision points.
- Know which profile you are using: prior day, overnight, developing, or composite. The developing POC tells you whether value is migrating.
- The method is level → reaction → order flow confirmation. Never level alone.
- Profiles are backward-looking and setting-dependent. They give you locations, not predictions.
