What Volume does, and when it works.
Volume Profile plots how much volume traded at each price level instead of over time, drawing a horizontal histogram. High-volume nodes (HVN) are acceptance/value areas that act as magnets and support; low-volume nodes (LVN) are rejection zones price tends to slice through.
The Point of Control (POC) — the single most-traded price — is one of the most reliable levels in crypto. Fixed Range lets you anchor the profile to a specific swing, which is how most discretionary traders use it.
Some Volume Profile variants on TradingView require a paid plan. It explains levels, it does not time entries.
