Trend structure, higher-highs/lower-lows, market phases

In Foundation you learned that uptrends make higher highs and higher lows. That definition is correct — but it isn't yet a rule. Which highs count? When exactly is a trend broken? Is the trend strong or tiring? At Practitioner level, you need answers that two traders looking at the same chart would agree on. That's what turns chart reading into something you can test.

What you'll learn

• An objective way to identify swing highs and swing lows
• How to read impulses and pullbacks to judge trend strength
• What a break of structure is — and why it isn't automatically a reversal
• The four market phases and what each means for strategy choice
• How to align structure across timeframes

1. Defining swings objectively

A trend is only as clear as the swings that define it. A common, testable definition:

• A swing high is a candle whose high is higher than the highs of the two candles on each side of it.
• A swing low is a candle whose low is lower than the lows of the two candles on each side.

This "2-left, 2-right" rule (some traders use 3 or 5) filters out tiny wiggles and gives you swing points anyone can reproduce. Many platforms have a built-in "fractals" indicator that marks exactly these points.

2. Impulses and pullbacks

A trending market alternates between two kinds of movement:

• Impulse — the move with the trend, making a new high (uptrend) or low (downtrend)
• Pullback (correction) — the move against the trend, before the next impulse

The relationship between them tells you how healthy a trend is:

Measuring pullback depth

Traders often express a pullback as a percentage retracement of the prior impulse.

(Illustrative.) An impulse runs from 1.0800 to 1.0900 (100 pips). Price pulls back to 1.0850.

• Retracement = (1.0900 − 1.0850) ÷ 100 pips = 50%

Pullbacks in healthy trends commonly retrace somewhere around a third to two-thirds of the impulse. Many traders mark 38.2%, 50%, and 61.8% (Fibonacci retracement levels) as reference zones. Treat them as areas to watch alongside support and resistance — not as magic numbers.

3. Break of structure

In an uptrend, the most recent higher low is the level the trend must hold. If price closes below it, the uptrend's structure is broken.

A break of structure means the trend is no longer confirmed — not that it has reversed. Three things commonly follow:

1. Reversal — a new opposite trend begins (lower high, lower low)
2. Range — price goes sideways
3. Resumption — the break was a deep pullback and the trend continues

Worked example

(Illustrative EUR/USD, H4.)

• Swing lows: 1.0780 → 1.0820 → 1.0855 (higher lows). Swing highs: 1.0850 → 1.0895 → 1.0930 (higher highs).
• Price falls and closes at 1.0845, below the last higher low of 1.0855. Structure is broken.
• The trader stops looking for buys. Price rallies to 1.0900 but fails below 1.0930 — a lower high — then drops below 1.0845.
• Now there's a lower high and a lower low: a new downtrend structure. Only now does the trader look for sells.

4. The four market phases

Markets tend to cycle through four broad phases:

This is an idealised model. Real markets skip phases, repeat them, and blur them together. The practical value is this question: "Is this market trending or ranging right now?" — because the answer determines which kind of strategy has a chance (Module 3.3).

5. Structure across timeframes

Structure can differ between timeframes. A D1 uptrend can contain an H1 downtrend (that's just a pullback on the higher timeframe).

A practical approach (see Timeframes and multi-timeframe basics):

1. Define trend direction on the higher timeframe using swing structure.
2. On the setup timeframe, wait for a pullback against that trend.
3. On the entry timeframe, wait for structure to turn back in the higher-timeframe direction — for example, an H1 break above the last lower high during a D1 uptrend pullback.

This aligns your entry with the larger trend while keeping your stop based on smaller, closer structure.

Common beginner mistakes

• Using vague swing definitions and "seeing" trends that aren't objectively there.
• Flipping bias on the first break of structure instead of waiting for new structure.
• Ignoring shrinking impulses and deepening pullbacks — early signs a trend is tiring.
• Treating Fibonacci levels as exact turning points rather than zones.
• Using trend strategies in ranges (and range strategies in trends).

Key terms

Practice

1. On an H4 chart of your market, mark every swing high and low for the last three months using the 2-left, 2-right rule (or a fractals indicator).
2. Label each swing HH, HL, LH, or LL. Where did structure break? What happened in the next 10 candles?
3. Measure the retracement of the last five pullbacks. Were they getting deeper or shallower?
4. Label the current market phase on D1 and write one sentence on which type of strategy suits it.

Quick recap

• Use a fixed, objective swing definition so your structure is testable.
• Impulse size and pullback depth reveal trend strength.
• A break of structure ends the confirmed trend — wait for new structure before reversing bias.
• Markets cycle through accumulation, markup, distribution, markdown — know whether you're trending or ranging.
• Align structure across timeframes: direction, pullback, entry.
