What a Volume Profile is
Take every contract traded in some period — a session, a week, a custom range — and stack it by the price it traded at rather than the time. The result is a sideways histogram on the price axis. Fat areas are prices where the market did a lot of business; thin areas are prices it rejected quickly. The core premise: the market remembers where it did business, and those prices behave differently on revisits than prices it ignored.
The three levels every profile gives you
Point of Control (POC)
The single price with the most traded volume — the session's most agreed-upon price. Rotational days tend to revisit the POC repeatedly; on trend days the POC lags behind price and marks where the last real acceptance happened.
Value Area (VAH / VAL)
The band around the POC containing (by convention) 70% of total volume, bounded by the value area high and value area low. Inside value = the market considers price fair; outside value = price is advertising for interest. Two classic reads: an open outside yesterday's value that gets accepted back inside often rotates across the whole value area, while an open that holds outside value signals imbalance and possible trend.
Profile highs and lows
The extremes show where the auction found no more business — rejection wicks in volume form.
HVNs and LVNs: the texture of the profile
- High Volume Nodes (HVNs) — local bulges. Acceptance zones: price tends to slow down and rotate inside them.
- Low Volume Nodes (LVNs) — local valleys between bulges. Rejection zones: price tends to move through them quickly, and they often act as support/resistance precisely because so little business was done there.
A useful mental model: HVNs are where the market parks; LVNs are the highways between parking lots. Level-based traders often place entries just inside an LVN, expecting the fast traverse to continue, with the neighboring HVN as target.
Naked POCs
A naked POC (also "virgin POC") is a prior session's point of control that price hasn't traded back through since. It's old, unfinished business — and futures traders track them because the market has a well-observed habit of returning to them days or even weeks later. Once price trades through the level, it's "filled" and comes off the list. A rigorous implementation checks the touch against the full trading-day tape (including overnight), not just the day session.
Session, composite, and range profiles
- Session profiles — one histogram per trading day. The daily working tool: today's developing value versus yesterday's finished value.
- Composite profiles — many sessions merged (a week, a month, a custom lookback). Composites surface the big structural HVNs/LVNs that single sessions can't show; a composite LVN (sometimes labeled CLVN) is a serious level because an entire multi-week auction rejected it.
- Range profiles — drawn over a hand-picked range (a swing, a consolidation) to find who's trapped where within that structure.
