High volume nodes HVN and low volume nodes LVN

When you study the shape of the profile you find it undulating: areas where the bars swell and others where they shrink. These are the volume nodes, and they are the key to understanding price behaviour.

Two opposing types

• The high node High Volume Node (HVN) — a wide bar, i.e. a level traded heavily. A zone of acceptance and balance where price slows and consolidates; it acts as strong support or resistance and draws price toward it.
• The low node Low Volume Node (LVN) — a thin bar, i.e. a level traded little. A zone of rejection that price crossed quickly, and it tends to reject it and bounce away rather than stop within it.
