How to Read Market Structure on a Currency Chart

Before indicators, before patterns, there is structure: the sequence of swing highs and swing lows that price leaves behind. Structure is the simplest honest description of a chart, and reading it well answers the first question every trader faces: which way should I lean?

Swings

A swing high is a peak with lower highs on each side; a swing low is a trough with higher lows on each side. Mark them on a clean chart and the noise drops away. What remains is a series of turning points.

An uptrend is a series of higher highs and higher lows. A downtrend is the reverse. A range is a sequence of highs and lows that fail to make progress. Nothing more is needed to classify a chart, and the classification is the foundation of everything that follows.

Breaks and shifts

Structure changes at identifiable moments. In an uptrend, the first time price makes a lower low is a warning. The first time it then fails to make a higher high is confirmation that the trend has at least paused. Traders call the first event a break of structure and the second a change of character. Neither is a signal on its own, but together they mark where the balance of control has shifted.

The reverse sequence applies in a downtrend. Note that one break in a strong trend is often a pullback rather than a reversal; two in a row deserve more respect.

Using structure to lean

• In an uptrend, look for buys at or near the most recent higher low
• In a downtrend, look for sells at or near the most recent lower high
• In a range, trade from the edges toward the middle, or wait for a break
• After a change of character, wait for the new structure to confirm itself before committing size

Stops belong beyond the swing that defines the trade. If you are buying a higher low, the stop goes below it, because a break of that low means the structure you relied on has failed.

Timeframes

Structure exists on every timeframe and they nest inside each other. A pullback on the daily chart is a downtrend on the hourly chart. Read the higher timeframe for direction and the lower one for timing, and expect the two to disagree for stretches.

What to watch

Watch the most recent swing in the direction of the trend, the first break that goes against it, and whether the next swing confirms or denies the break. Keep the chart clean enough that the swings are obvious at a glance.
