How to Spot a Break of Structure
To spot a break of structure, mark the most recent swing high and swing low first, then watch for price exceeding one of them in the direction the trend was already going. Marking the swings before the break is what stops the pattern being drawn after the fact.
A break of structure is price exceeding a prior swing point in the direction the trend was already moving. It is a continuation marker, and everything about whether it is useful depends on the swings having been marked before the break rather than after it.
Before you start
A marked swing high and swing low, drawn before anything is called a break. Two lines on the chart, placed when nothing is happening.
A rule for whether a wick counts or only a close. They disagree frequently, and deciding afterwards means deciding by outcome.
One timeframe, chosen in advance, because structure differs on every one. A break on the hourly can be an ordinary bar on the daily.
The steps
1. Mark the most recent swing high and low
A swing high is a bar whose high exceeds the bars either side of it. Mark the most recent clear one in each direction and leave them alone.
2. Establish which direction the trend already had
A sequence of higher highs and higher lows is an uptrend. Exceeding the swing high in that context is a break of structure; exceeding the swing low is something else entirely.
3. Apply your wick-or-close rule
A close beyond is the stricter test and produces fewer, later signals. A wick through produces more and earlier ones. Either is defensible; changing between them is not.
4. Check the break against ordinary movement
On this site’s shared series the median bar range is 0.493 and the ninetieth percentile is 1.101. Price exceeding a level by a tenth of an ordinary bar is inside the noise.
5. Mark the new swing point immediately
Once broken, the old level is spent and a new swing forms behind the move. Marking it straight away is what keeps the framework prospective rather than retrospective.
6. Treat it as context, not as an entry
The break tells you the trend is intact. Where you get in is a separate decision, usually on a retracement rather than at the level itself.
7. Take the stop from the last swing
Below the swing low that preceded the break, for a long. That is a structural level, and the distance to it sets the position size.
How to tell it worked
Both swing levels were marked before the break occurred, not after.
The wick-or-close rule was applied consistently, with 0 exceptions.
The break exceeded the level by more than 1 ordinary bar range, measured rather than assumed.
And a new swing point was marked within 5 bars of the break, keeping the framework current.
What it does not tell you
Whether the move continues. On this site’s shared series price traded through 85% of 39 twenty-bar levels, so exceeding a prior level is the ordinary case rather than an unusual one.
Whether anybody participated. The framework reads price alone, so a break driven by real volume and one driven by a single order at a quiet moment look identical.
Why marking beforehand is the entire discipline
Swing points are obvious in hindsight and ambiguous live. On a completed chart the significant highs and lows are visible; on the right-hand edge there are several candidates and no way to know which will matter.
Which means an unmarked chart always produces a clean reading of the past. Every trend has a tidy sequence of breaks when you draw them after the fact, and none of that says anything about what the same exercise would have produced in advance.
Two lines, drawn when nothing is happening, is the whole fix. It costs nothing and it converts the framework from a way of describing charts into something that can be wrong.
Break of structure against change of character
A break of structure continues the existing direction. Higher highs in an uptrend, lower lows in a downtrend. It is a confirmation that nothing has changed.
A change of character is the first break in the opposite direction. In an uptrend, price taking out a prior swing low rather than a swing high. Same mechanic, opposite implication.
Which means the two are distinguished only by the trend you had already established. The same bar exceeding the same level is one or the other depending entirely on what you decided the direction was beforehand.
And that is why the direction has to be written down. Deciding what the trend was after seeing which level broke guarantees you always have the right label and never a testable claim.
The original data
Of the 24,971 unique videos in research/search-study-corpus.jsonl, 51 mention this pattern in the
title, at a median of 4,891 views across 43 channels, and 57% of those titles are instruction-shaped.
Order blocks appear in 391 at 2,786, fair value gaps in 150 at 28,170 and market structure in 74 at
9,296. The counts come from site/corpus_count.py and site/rank_howto.py.
51 videos at 4,891 against 391 on order blocks at 2,786. The structural framework that gives the other concepts their meaning has an eighth of their coverage, which is a reasonable summary of how this material is usually taught — the entries first, the framework afterwards if at all.
The answer to the question on that chart is that your rule already decided. If you are trading closes, that is not a break — and making an exception because this one looks convincing is how a rule becomes a preference, one reasonable exception at a time.
When it fails
The failure is structure drawn after the move, and it produces a framework that has never once been wrong. Looking back at a completed chart, every trend shows a tidy sequence of breaks and every reversal is preceded by a clear signal. The swings were chosen knowing what followed. Applied live, with several candidate swing points and no outcome available, the same framework produces ambiguity — and the gap between those two experiences is invisible to anyone who only ever practises on history.
The second failure is switching between wick and close. That decides by outcome.
A third is mixing timeframes. Structure differs on each.
A fourth is entering at the level. The break is context, not a trigger.
A fifth is ignoring the size of the break. A fractional exceedance is noise.
And a sixth is not updating the swings. The framework goes stale in a few bars.

Break of structure covers the pattern itself. Market structure is the framework it belongs to. And swing high and low is how the levels are identified in the first place.
The rule that made this honest was marking the swing levels before anything happened and not moving them afterwards. Left unmarked, I was finding the break after the move and calling it structure, which is a description of the past dressed up as a reading of the present.
