Higher highs, higher lows, lower highs, lower lows

Each new swing high and low is labelled by comparing it with the previous one: higher high (HH), higher low (HL), lower high (LH) and lower low (LL). The sequence of these labels makes the direction of the trend measurable.

HL HH HL HH HL LH LL LH LL LH Rising structure HH and HL Falling structure LH and LL
Each high is labelled against the previous high and each low against the previous low. The first high has no label because there is no earlier high to compare it with. The dashed line marks where the sequence changes.

What do the four labels describe?

On their own, swing highs and lows only show where price changed direction. To read the structure, we compare each new high with the previous high and each new low with the previous low. The abbreviations are widely used on charts.

The comparison is always between points of the same kind: high with high, low with low. Comparing a low with the previous high says nothing about the structure.

The labels

  • HH (higher high): The new high is above the previous high.
  • HL (higher low): The new low is above the previous low.
  • LH (lower high): The new high is below the previous high.
  • LL (lower low): The new low is below the previous low.

If a high or low is at almost the same level as the previous one, it counts as neither higher nor lower. Equal highs and lows like these often point to a sideways market.

How the sequence defines the trend

A single label does not set the trend. The trend is read from how the labels line up one after another.

Uptrend

Highs line up as HH and lows as HL. Each pullback ends above the previous low.

Downtrend

Highs line up as LH and lows as LL. Each bounce ends below the previous high.

Mixed or sideways

The labels mix, for example an HH followed by an LL, or highs and lows stay at the same levels. There is no clear direction.

How to label a chart

  1. Mark the significant swing highs and lows. Use points picked on the same timeframe with the same rule. Including minor swings muddles the labels for no reason.
  2. Compare each point with the previous one. Compare each high with the previous high and each low with the previous low, and label it HH, HL, LH or LL.
  3. Look at the last few labels. The last two highs and the last two lows together describe the current structure. Much older labels do not change today's structure.
  4. Note where the sequence breaks. In a rising structure the first LH or first LL, and in a falling structure the first HH or first HL, is where the structure starts to change.

What it shows, what it does not prove

What it shows

  • Whether the structure on this timeframe has been rising, falling or sideways so far
  • At which point the trend started to weaken
  • A way to define the trend from price alone, without lines or indicators

What it does not prove

  • That the next high or low will follow the same sequence
  • That a single LH or LL reverses the trend on its own
  • That the same sequence holds on other timeframes

How it relates to zones

In a rising structure, higher lows often form on or inside a support zone. In a falling structure, lower highs similarly stay below or inside a resistance zone. The labels make it easier to see how zones work within a trend.

If the difference that makes a low "higher" or "lower" than the previous one is very small, both lows may sit inside the same zone. In that case it is sounder to read the points within a band than to treat a few units of difference as a change of direction.
