What is Break of Structure (BOS)?

When price closes beyond a significant swing point, confirming trend continuation or reversal.

The DefinitionBreak of Structure (BOS), defined

A Break of Structure (BOS) occurs when price closes beyond a prior swing high (in an uptrend) or swing low (in a downtrend). A BOS in the direction of the trend confirms continuation. A BOS against the trend — often called a Change of Character (CHoCH) — is the first signal that the trend may be reversing. BOS is one of the strongest Reveals in the RRR framework because it's the market showing its hand at a structural level.

Why It MattersWhy Break of Structure (BOS) matters

A BOS isn't a wick poking through a level — it's a close beyond it. That distinction filters out most fake-outs and keeps you on the right side of the real move.
