Cite as: TradeLabs Learn, "Swing Highs and Lows", https://learn.tradelabsai.com/price-action/swing-highs-and-lows/ A swing high is a turning point where price rose, peaked and then fell. A swing low is the opposite: price fell, bottomed and then rose. These turning points are the skeleton of every chart. Market structure, support and resistance, trend lines and stop placement all start with identifying swing points correctly. ## A simple definition | Swing point | Rule | Meaning | |---|---|---| | Swing high | A candle whose high is higher than the highs of the candles on either side | Buyers ran out of strength there | | Swing low | A candle whose low is lower than the lows of the candles on either side | Sellers ran out of strength there | How many candles on each side? A common rule is two, which makes a five candle pattern. Bill Williams popularised this five bar structure as a "fractal", and many charting platforms include a fractals indicator that marks these points automatically. *Figure: A five candle swing high: the middle high is above the two highs on each side.* ## Strength of a swing Not all swings are equal. A swing is more significant when: - **More candles confirm it,** for example the highest high in 20 candles rather than in 5. - **It appears on a higher timeframe,** such as a daily rather than a 5 minute swing. - **Price reacted strongly** away from it, with a large move afterwards. - **It aligns with other levels,** such as round numbers or previous support and resistance. Traders often separate **major swings**, which define the main trend, from **minor swings** inside them. See [Internal vs External Structure](https://learn.tradelabsai.com/price-action/internal-vs-external-structure/). ## Confirmation takes time A swing high is only confirmed after the candles that follow it have formed lower highs. With a two candle rule, you know a swing high existed two candles after it happened. This lag is unavoidable: in real time, every high could be the start of a bigger move. Be careful when backtesting rules based on swings not to use information that was not yet available. See [Look-Ahead Bias](https://learn.tradelabsai.com/research/look-ahead-bias/). ## How traders use swing points 1. **Define the trend:** a series of higher swing highs and lows is an uptrend. See [Trend Structure: Higher Highs and Lower Lows](https://learn.tradelabsai.com/price-action/higher-highs-and-lower-lows/). 2. **Place stops:** below the most recent swing low for a long trade, above the most recent swing high for a short. See [Stop Loss Strategies](https://learn.tradelabsai.com/risk/stop-loss-strategies/). 3. **Mark support and resistance:** previous swing highs often act as resistance, swing lows as support. See [Support and Resistance](https://learn.tradelabsai.com/price-action/support-and-resistance/). 4. **Set targets:** the next swing high above or swing low below is a natural first target. 5. **Draw trend lines** by connecting swing lows in an uptrend or swing highs in a downtrend. See [Trend Lines](https://learn.tradelabsai.com/price-action/trend-lines/). **Example: Placing a stop from swings** In an uptrend, a stock's latest swing low is $61.20 and it is now trading at $64.00 after bouncing. A trader buys at $64.00 and places a stop at $60.90, just below the swing low. If price breaks below $61.20, the uptrend's structure is damaged, so exiting there is logical rather than arbitrary. ## Common mistakes - **Marking every tiny wiggle,** especially on low timeframes, which creates noise. - **Changing the rule** from chart to chart; consistency makes your analysis comparable. - **Ignoring confirmation lag** and treating the current high as a confirmed swing. - **Placing stops exactly at the swing point,** where many other stops cluster; a small buffer often helps. ## Frequently asked questions ### What is a swing high in trading? A peak where a candle's high is higher than the highs of the surrounding candles, marking a point where buying pressure faded. ### How many candles define a swing? There is no single rule; two candles on each side is common, but traders use more for stronger, less frequent swings. ### Are swing points the same as support and resistance? They often become support and resistance levels, because traders remember where price turned before.
