Break of structure
Family XII · Other terms
Not to be confused with forex market structure, market structure.
Break of structure is a descriptive label used in price-action analysis for the event in which price closes past a swing point that had defined the prevailing sequence of higher highs and higher lows, or lower highs and lower lows. It is identified after the fact on a chosen timeframe, and its significance depends entirely on which swing points the analyst has marked. A break confirms only that the prior sequence has ended; it does not by itself indicate the direction of whatever follows.
How a break is identified
The method is mechanical once swing points are defined. In an uptrend, price prints a series of higher highs and higher lows; the most recent higher low is the level that matters. A candle close below that low is a bearish break of structure. In a downtrend, the mirror applies: a close above the most recent lower high is a bullish break.
- Swings are usually defined by a fractal rule, such as a high with lower highs on both sides, or by a fixed lookback.
- Wicks through the level are commonly disregarded; the close is the trigger.
- Timeframe choice changes the result. A break on a five-minute chart may sit inside an intact sequence on a daily chart.
- Because swing identification is rule-dependent, two analysts using different rules can disagree about whether a break has occurred.
Worked example
An uptrend on a daily chart has produced a swing high at 1.2400 and a subsequent higher low at 1.2150. Price later closes at 1.2080.
The sequence of higher lows is broken. The next lower high becomes the reference for judging whether the new downward sequence continues.
What it does and does not imply
A break of structure is a statement about the past sequence, not a forecast. Traders often treat it as the first stage of a possible reversal, but a break can also occur inside a pullback within a larger trend on a higher timeframe. Confirmation is usually sought through a subsequent lower high (in the bearish case) or higher low (in the bullish case), or through a retest of the broken level.
Terminology and confirmation conventions vary between analysts, educators and platforms; no single rule set is standard.
Often confused with
- forex market structure
- Forex market structure describes the general framework of swing highs, swing lows and trends in currency pairs, whereas a break of structure is one specific event within that framework; the visible sign is that the former is a standing description and the latter is a dated occurrence.
- market structure
- Market structure is the overall pattern of highs and lows across any instrument, while a break of structure is the single moment one of those reference points is closed through; the visible sign is that market structure persists until changed, whereas a break is a discrete event.
