Market structure

A chart description based on the sequence of visible swing highs and swing lows.

Readers compare successive turning points using labels such as higher high, higher low, lower high and lower low. The sequence helps describe whether price has been rising, falling or ranging.

A higher high followed by a higher low is one observation within a rising structure; more context is needed before describing a sustained trend.

Swing selection is sensitive to scale and method. Structure describes the chosen chart history and is not a forecast.

The four labels

Each new swing is compared with the last swing of the same kind: a high with the previous high, a low with the previous low.

LabelMeaning
Higher high (HH)A swing high above the previous swing high
Higher low (HL)A swing low above the previous swing low
Lower high (LH)A swing high below the previous swing high
Lower low (LL)A swing low below the previous swing low

How a swing is picked

A swing high is a bar whose high is above the highs of the bars on either side of it; a swing low is the same with lows. How many bars on each side you require changes which turning points count. The example below uses three bars on each side of daily bars.

Change the timeframe or the number of bars and the labels change with them. That is why two people can describe the same chart differently and both be consistent.

A real example: gold, May to September 2026

Every swing on our broker's daily gold chart from 21 May to 23 September 2026, labelled against the previous swing of the same kind. It shows the vocabulary on real prices; it is a description of what already happened, not a prediction.

Read down the table: lower lows and lower highs through June, higher lows from mid July, two higher highs in August, then lower lows and lower highs again in September.
