What Are Swing Highs and Swing Lows?

A swing high is a local peak and a swing low is a local trough under a chosen rule. They are reference points for reading price structure, not fixed support or resistance guarantees.

A local pattern needs a rule

One system may require two lower highs on each side of a peak; another may use a wider window or an amount of price movement. Because the right side of the pattern must form, a newly proposed swing point can remain unconfirmed for several bars.

Breaks require context

Suppose a hypothetical stock's last confirmed swing high is $101. A trade at $101.20 has crossed that level, but the meaning depends on the timeframe, feed, and whether price remains above it. A quick return below the level is one reason traders distinguish an attempted breakout from a sustained move.

Compare timeframes

A five-minute swing high can occur inside a larger hourly downswing. State which timeframe and rule produced the level. The combined chart can display swing levels and trend lines; read those overlays in the context of the selected timeframe and available chart data.
