Volume profile groups activity into price rows over a selected period. It describes where the supplied data records trading, rather than how much activity occurred in each time bar.

Read the Profile Settings First

A session profile, fixed-range profile and visible-range profile can cover different observations. Row size also matters: combining nearby prices into wider bins can move the largest row. A profile may estimate distribution from lower-timeframe bars instead of using every individual trade.

The point of control is the price row with the largest recorded volume. A value area collects a chosen proportion of profile volume, often using a 70% setting and a platform-specific expansion method. High- and low-volume nodes are relative concentrations and gaps within that histogram. TradingView documents its calculation and volume sources.

These labels do not establish fair value. The POC is not necessarily an exact single traded price, and a value area is not a confidence interval for future prices.

Past Activity Is Not Current Order Availability

A high-volume row tells you many units traded there in the selected data. It does not prove that their owners still hold positions or will defend the level. A low-volume row does not prove that the current order book is thin.

For that reason, price does not have to return to a “magnetic” POC or accelerate through every low-volume node. Treat those reactions as hypotheses, and record the occasions when they fail.

Avoid a Developing-Profile Lookahead Error

A session's final POC and value area are only known at the end of that session. If you trade during it, save the values available at the decision time. Using the completed profile to place earlier trades introduces future information.

Yesterday's completed profile is a different input from today's developing one. Keep that distinction explicit, including the session timezone and whether overnight activity is included.

Test a Specific Retest Rule

For a value-area re-entry hypothesis, define the opening location, entry trigger, target, stop and session cutoff. Record every eligible case and account for costs. The label “80% rule” is not evidence that your strategy succeeds 80% of the time.

Confirm whether the feed contains actual traded units or tick updates and whether it covers the venue you trade. Do not assume a subscription includes a particular profile feature or the market-data entitlement; check the current platform offering.
