What is a low volume node?

A low volume node is a thin stretch of the profile where little business printed. Price passed through those prices too fast for positions to build. That is a record of imbalance: almost nobody agreed to trade there.

Thin areas are why fast moves stay fast. Fewer established positions sit in the path, so price has room to travel. When a move enters a low volume node, it often gets pulled through like a vacuum until it reaches the next area where business actually happened.

The same node gives two reads. A sharp rejection from a low volume node can be a trade back toward value. No reaction while price drives into it means the travel likely continues. A low volume node is a doorway between accepted areas. The response at the doorway tells you which side is in control.
