What is Swing high / swing low?

A swing high is a peak on the chart where price turned down after a rise; a swing low is a trough where price turned up after a fall. These turning points are the skeleton of market structure — trends, trendlines, support and resistance are all built by connecting swing highs and lows.

A swing high is a candle whose high stands above the candles on either side of it — a local peak where an up-move ran out of buyers and reversed. A swing low is the mirror: a local trough where a down-move ran out of sellers and turned up. They mark the pivots of price, the points where the balance of power flipped. Larger swings (major turning points) matter more than tiny ones; how many candles you require on each side sets how 'significant' a swing has to be to count.

Swing points are the raw material of technical analysis. A trend is defined by the pattern of swings — higher highs and higher lows for an uptrend, lower highs and lower lows for a downtrend. Trendlines are drawn by connecting swing lows (or highs). Support and resistance form where swings cluster. A break of a prior swing high or low is one of the clearest signals that structure has changed. Reading swings is how a trader turns a wiggly line into a map of who's winning.

Swing highs and swing lows

The local peaks (swing highs) and troughs (swing lows) are price's turning points — the skeleton of market structure that trends, trendlines and support/resistance are built from.

For example

A stock rises to $58, turns down (a swing high), falls to $52, turns up (a swing low), then rises past $58 to $61. That new high above the prior swing high confirms the uptrend is making higher highs.

Why it matters to you

Swing highs and lows are the alphabet of market structure — you can't read a trend, draw a trendline, or place a logical stop without them. Learning to spot the meaningful pivots turns a chart from a random squiggle into a readable sequence of turning points that tells you exactly when structure holds or breaks.

⚠ Not every wiggle is a swing

Marking every tiny bump as a swing point clutters the chart and produces false structure. The meaningful swings are the ones that stand out — the pivots a reasonable observer would point to. Requiring a few candles on each side, and focusing on the larger turning points, keeps swing analysis clean and useful.

Frequently asked questions

What is a swing high and swing low?

A swing high is a local peak — a candle whose high is above those around it, where price turned down. A swing low is a local trough where price turned up. They're the turning points of price, and connecting them defines trends, trendlines, and support and resistance.

How do you identify swing points?

A common method requires a candle's high (for a swing high) or low (for a swing low) to exceed a set number of candles on each side — often two or three. The more candles you require, the more significant the swing. Focus on the larger, obvious pivots rather than every tiny wiggle.

Why are swing highs and lows important?

Because they're the building blocks of market structure. A trend is a pattern of swings (higher highs and lows, or lower highs and lows); trendlines connect them; support and resistance form where they cluster; and a break of a prior swing signals structure has changed.

What does it mean when price breaks a swing high?

Breaking above a prior swing high means price made a higher high — bullish, confirming or extending an uptrend. Breaking below a prior swing low means a lower low — bearish. These breaks of prior swing points are among the clearest signals that market structure is shifting.
