HH / HL / LH / LL

Market structure analysis uses Higher High (HH), Higher Low (HL), Lower High (LH), and Lower Low (LL) as a common language. These concepts let us describe how significant swing points relate to each other rather than simply calling a chart bullish or bearish.

The four terms form one connected structural method. The objective is not to predict the next movement with certainty, but to determine which structure is currently valid and what price event would change our interpretation.

1. The Four Basic Concepts

HH — Higher High: a significant new swing high above the previous relevant swing high.

HL — Higher Low: a significant correction low above the previous relevant swing low.

LH — Lower High: a significant new swing high below the previous relevant swing high.

LL — Lower Low: a significant new swing low below the previous relevant swing low.

The comparison is always made with the appropriate previous structural point.

2. Higher High — HH

A Higher High forms when a new significant swing high is above the previous relevant swing high.

Example: 100 → 115 → 108 → 123. Since 123 > 115, 123 is a Higher High. HH is bullish information, but it is not enough by itself to define a complete bullish structure; the behavior of the lows must also support it.

3. Higher Low — HL

A Higher Low forms when a correction low remains above the previous relevant swing low.

Example: 100 → 115 → 108 → 123. Since 108 > 100, 108 is a Higher Low. HL is especially important in an uptrend because it shows that the opposing move could not reach the previous structural low.

4. HH + HL Create the Upward Structure

A typical bullish sequence is HH → HL → HH → HL → HH.

Example: 100 → 115 → 108 → 123 → 114 → 132. Here 115 and 123 and 132 are HHs, while 108 and 114 are HLs. Each impulse creates a higher high and each correction remains above the preceding structural low.

5. Lower High — LH

A Lower High forms when a new significant swing high remains below the previous relevant swing high.

Example: 150 → 135 → 142 → 125. Since 142 < 150, 142 is a Lower High. LH is an important building block of bearish structure because the market can no longer recover to the previous structural high.

6. Lower Low — LL

A Lower Low forms when a new significant swing low is below the previous relevant swing low.

Example: 150 → 135 → 142 → 125. Since 125 < 135, 125 is a Lower Low. LL shows that sellers have been able to push price below a previous structural low.

7. LH + LL Create the Downward Structure

A typical bearish sequence is LL → LH → LL → LH → LL.

Example: 150 → 135 → 142 → 125 → 132 → 116. The sequence contains LLs at 135, 125 and 116, while 142 and 132 are LHs. The market is creating progressively lower highs and lower lows.

8. The Four Concepts as One System

Bullish structure = HH + HL.Bearish structure = LH + LL.

A real chart is rarely perfectly ordered. Markets often move through transitional states, so the appearance or disappearance of one component must be interpreted in context rather than treated as an isolated signal.

9. When Structure Begins to Weaken

Consider 100 → 115 → 108 → 125 → 117 → 135. This is clearly bullish. Now imagine 135 → 124 → 130 → 116.

The 130 high is below 135, so it is an LH. The 116 low is below 117, so it is an LL relative to the previous relevant low. The market has begun producing bearish structural elements.

The important change is therefore HH + HL structure → appearance of LH + LL.

10. Not Every HH, HL, LH or LL Has Equal Importance

Charts contain many minor local highs and lows. If every one is labeled as structural, the analysis quickly becomes contradictory.

We therefore identify relevant swing points. Their importance can increase when a strong impulse starts from them, when that impulse breaks an important prior level, when the movement spans a meaningful correction, when the point is visible on a higher timeframe, or when it becomes a clear reference for other market participants.

The objective is not to label every fluctuation, but to identify the meaningful structure.

11. Interpreting Structure in Real Time

After the fact, HH, HL, LH and LL points are easy to identify. In real time, it is harder to know whether a current high or low will become structurally significant.

A swing point often becomes more convincing only after price has moved away from it and another structural event has occurred. Professional analysis therefore relies on confirmation and context rather than retrospective labels alone.

12. HH/HL/LH/LL and Structure Breaks

The four concepts let us describe trend damage more precisely. For example, a bullish sequence may be HH → HL → HH → HL → HH. If price falls below the latest HL, the bullish structure is damaged.

That does not automatically mean “the market is now bearish.” We then examine whether price can establish LH → LL. The HH/HL/LH/LL framework therefore lets us interpret structural change as a process rather than a single event.

13. Practical Case Study

Consider: 80 → 95 → 88 → 105 → 98 → 113 → 103.

The structure is bullish: 95, 105 and 113 are HHs; 88, 98 and 103 are HLs because 103 remains above 98.

Suppose price then rises to 109 and falls to 94. Now 109 < 113, so it is an LH, and 94 < 98, so it is an LL.

The sequence becomes HH → HL → HH → HL → HH → LH → LL. The market has not merely fallen; the previous HH/HL structure is beginning to be replaced by an LH/LL structure.

14. Structure and Trading Decisions

HH/HL/LH/LL does not provide an automatic entry signal. It defines market context.

For example: HH + HL → bullish environment → correction → HL holds → new HH → continuation scenario becomes better supported.

Likewise: LH + LL → bearish environment → correction → LH forms → new LL → bearish continuation becomes better supported.

Specific entry rules will be connected to strategy conditions in later lessons.

15. Common Mistakes

Treating every local high as an HH; treating an HH alone as a bullish signal; treating the loss of one HL as an automatic short signal; analyzing structure on an excessively low timeframe; and projecting retrospective certainty onto real-time decisions.

A structural point must be relevant, the whole sequence must be considered, and uncertainty must be acknowledged.

Practical Exercise

Choose a liquid stock or ETF and mark significant HH, HL, LH and LL points. Identify the current structure, the last valid structural point, and the price level whose loss would damage that structure.

Then describe the transition in words: “The market was initially in an HH/HL structure, then…”The objective is to learn to read a structural story from the chart rather than merely looking at price movement.
