Low-volume gaps are not automatic magnets

Low-volume gaps sit between high-volume nodes where little trade occurred during a move. Textbooks sometimes treat them as magnets that price must revisit. Live markets are messier: thin areas can act as highways in a continuing auction or as zones that price slices through once and never revisits.

Before you assume a fill, ask what created the gap — news impulse, overnight inventory, or a short squeeze — and whether the adjacent nodes still hold buyers or sellers. A gap under a strong high-volume node behaves differently from a gap left after a weak overnight print.

In our clinics we score charts for gap context first, trade idea second. That habit cuts the number of forced mean-reversion bets that ignore the auction that produced the thin print in the first place.
