Break of Structure

A continuation signal (BOS) in which price closes beyond the most recent swing high (in an uptrend) or swing low (in a downtrend), confirming that the prevailing trend is extending.

A Break of Structure occurs when price decisively breaches the prior significant pivot in the direction of the existing trend — closing above the last swing high in an uptrend, or below the last swing low in a downtrend. It is the event that confirms a trend is continuing: each BOS marks a fresh higher high or lower low that extends the structural sequence. The term comes from Smart Money Concepts but describes the same continuation logic as a Dow Theory trend confirmation.

A BOS tells you the trend is still in force and validates trading in its direction — after an upward break, the next pullback to a higher low is a continuation entry. It is distinct from a Change of Character, which breaks structure against the trend. Traders use a confirmed BOS to stay aligned with momentum and to define the new pivot that must hold for the trend to remain intact.

As a continuation signal a BOS is relatively reliable because it trades with the dominant trend — the higher-probability side — and is defined by an objective price event rather than an interpretation. Its weaknesses are lag (the break confirms only after price has already moved) and false breaks: price can poke through a level intrabar and snap back, so a close-based confirmation and supporting volume matter. A BOS is most reliable in clearly trending markets and least reliable in ranges, where apparent breaks frequently fail. It pairs naturally with pullback entries and with confluence at the broken level.
