Glossary / Market structure

Break of structure (BOS)

An educational concept. Not a signal, not a strategy, and not a trade Josh has taken.

Stepped white and ice-blue blocks forming a rising landscape, an unlabeled picture of market structure.
Illustration of the idea, not a market chart and not a result.

Price moving beyond the most recent swing point in the direction of the existing trend: a new higher high in an uptrend or a new lower low in a downtrend. It suggests the trend is continuing.

How traders use it: Many structure traders wait for a BOS, then look for a pullback into a zone created by the move before planning an entry.

Common mistake: Counting a wick through the swing as a break when the candle closed back inside. Decide in advance whether a body close is required.
