A swing high is a candle whose high is above the candles on both sides of it; a swing low is the mirror. Reading these points in order gives market structure: higher highs with higher lows is an uptrend, lower highs with lower lows is a downtrend. A trend ends when that order breaks — a mechanical test rather than a judgement call.
A swing high is a candle whose high is above the candles on either side. A swing low is a candle whose low is beneath the candles on either side.
These points are the skeleton of every chart. Trendlines approximate them, patterns are built from them, and trends are defined by the order they appear in.
Why this beats “it looks bullish”
The value of swing points is that they are mechanical.
“Is this an uptrend?” is a matter of opinion. “Is this peak higher than the last peak?” is not — you can point at it, and two people will agree.
That is the whole reason this part exists before patterns and indicators.
Two practical notes.
Swing points confirm late. A candle is only a swing high once the following candles have failed to exceed it. There is an unavoidable delay between the peak forming and being identifiable — no method removes this.
They are timeframe-specific. A 15-minute swing high may be invisible on the daily chart. When two people disagree about whether structure broke, they are usually reading different timeframes — the Part 3 problem again.
The sequence is the trend
Read the swing points in order and the trend defines itself.
- Higher high, higher low, repeating — uptrend, intact
- Lower high, lower low, repeating — downtrend, intact
- Mixed — range or transition
This gives a precise answer to a question most beginners answer by feel: has the trend ended?
The two events that end a trend
An uptrend does not reverse in one move. It breaks in two steps, and the order matters.
Step 1 — a lower high. The uptrend is now in question. Not broken. Step 2 — price takes out the previous higher low. Now it is broken.
Until both happen, a decline is a pullback, not a reversal. Getting this wrong causes the two most common trend-trading errors: exiting a good trend at the first dip, and holding a broken trend because it “should” recover.
Key takeaway Structure gives you a sentence you can test: “this uptrend is intact while price holds above [the last swing low].” Entry, stop, invalidation and the decision to stay in can all be derived from that one line.
Why price hunts these levels
Swing points are where stop orders live — and knowing this explains a lot of frustrating price action.
A trader who buys a pullback puts their stop beneath the swing low that defined it, because that is where the idea is wrong. So does the next trader, and the next. A pool of resting sell orders builds just beneath an obvious low.
Resting orders are liquidity, and markets move toward liquidity.
The response is not to abandon logical stop placement. It is to place stops beyond the swing with a buffer sized to how much the instrument normally moves — and to accept the smaller position that follows, rather than tightening the stop to afford a bigger one.
Using structure in a trade
Direction — trade with the higher-timeframe structure. Counter-trend trades are lower-probability by construction.
Entry — in an uptrend, the pullback toward the prior swing low is where risk is smallest relative to the move. That is Part 9.
Stop — beyond the swing that would invalidate the read, plus a buffer.
Exit — structure can close a trade too. An uptrend that produces a lower high has changed character, which is a reason to reduce before the stop is hit.
Next: Breakouts and false breakouts — what happens when structure is challenged, and why most challenges fail.
- A swing high has lower highs immediately on both sides of it.
- Market structure is the sequence of swing highs and lows, read in order.
- A trend ends when the sequence breaks — this is checkable, not a matter of opinion.
- Stop orders cluster just beyond swing points, which is why price reaches for them.
