A weak low occurs when the market stops exactly at a prior reference (e.g., a prior day’s low, halfback, VWAP, or a round number like 25,000).

It shows that the market is respecting an obvious reference level, usually one that short-term or weaker hands are watching.

It suggests that stronger, longer-term players have not yet tested or defended that area.

Interpretation: Weak lows often get revisited, because the auction hasn’t truly explored that level.
