Chart patterns trading — how to read stock charts like a trader.

Chart patterns are specific formations that appear on price charts as a result of shifting supply and demand. In chart patterns trading, these formations are the visual language of the market — they reflect the collective psychology of buyers and sellers, capturing fear, greed, hesitation, and conviction in repeatable shapes. Because human behaviour repeats, chart patterns repeat, making them one of the most practical tools for reading stock charts and anticipating price direction.

Every stock chart pattern falls into one of two categories: reversal patterns, which signal the current trend is losing momentum and preparing to change direction, and continuation patterns, which signal the trend is pausing to consolidate before resuming. Mastering this distinction is the first step in learning how to read stock charts effectively.

The head and shoulders pattern is one of the most widely recognised and reliable stock chart patterns for trend reversal trading. It forms at the end of an uptrend and signals that bullish momentum is exhausting as sellers begin to take control.

The structure consists of three distinct peaks: a left shoulder (initial high), a higher head (the final push higher), and a right shoulder (a failed rally to roughly the same level as the left). The neckline connects the troughs between the three peaks. A decisive close below the neckline on above-average volume confirms the reversal. In chart patterns trading, the measured price target is calculated by projecting the distance from the head to the neckline downward from the breakout point.

The inverse head and shoulders pattern forms at the bottom of a downtrend and signals a bullish reversal. The same structure applies in reverse: a break above the neckline on rising volume confirms the pattern and suggests a sustained move higher.

The double top pattern forms when price tests a resistance level twice and fails to break higher on both attempts, creating two roughly equal peaks separated by a trough. The pattern is confirmed when price breaks below the trough (the neckline), signalling that buyers have exhausted their strength. In chart patterns trading, the double top is a powerful bearish reversal signal, especially when it appears after a prolonged uptrend.

The double bottom pattern is the mirror image — price tests a support level twice, bounces each time, and breaks above the middle peak to confirm a bullish reversal. Double bottoms generally form over longer periods than double tops and are considered more reliable as a result.

Both patterns are especially powerful when they coincide with key support and resistance levels identified through independent analysis. See our support and resistance guide for more on identifying those levels.

Triangle patterns form when price compresses into a narrowing range with converging trendlines. They are typically continuation patterns — meaning price tends to break in the direction of the prevailing trend — but each triangle variant has distinct characteristics that affect how you trade it.

Ascending triangle

Defined by a flat resistance level and a series of rising support lows. This pattern signals that buyers are increasingly aggressive and typically resolves with an upward breakout. One of the more reliable stock chart patterns for bullish continuation trades.

Descending triangle

A flat support level with declining resistance highs. Sellers become more aggressive with each test of support, and a downward breakout is the typical resolution. Considered a bearish continuation signal.

Symmetrical triangle

Converging lower highs and higher highs with no inherent directional bias. The breakout direction — confirmed by a volume spike — determines the signal. Volume confirmation is especially critical for symmetrical triangles, which produce the highest rate of false breakouts if traded without it.

Flags and pennants are short-term continuation patterns that form after a sharp, directional price move. In chart patterns trading, they are prized for their clear structure, quick resolution, and reliable measured move targets.

A flag appears as a small rectangular channel that slopes against the prevailing trend. A pennant is a small symmetrical triangle that forms after a sharp move. Both share the same behavioural signature: volume declines during the consolidation phase as traders pause, then spikes sharply on the breakout as the trend resumes.

The measured price target for flags and pennants is approximately the height of the prior trend leg projected from the breakout point. These patterns work best in strongly trending markets and are less reliable in choppy, sideways conditions. Pair them with a broader trend analysis for the best results in your chart patterns trading approach.

The cup and handle pattern is a bullish continuation formation that is instantly recognisable once you know what to look for. It resembles the outline of a tea cup: a rounded bottom (the cup) followed by a short pullback (the handle) before the breakout. In chart patterns trading, it is considered one of the most reliable setups for capturing sustained uptrends.

Key characteristics to assess when learning how to read stock charts for the cup and handle: the cup should be U-shaped (not V-shaped — a V-shape suggests a sharp reversal, not healthy consolidation); the handle should retrace no more than one-third of the cup’s advance; and the breakout above the handle’s resistance level should be accompanied by a clear increase in volume. The price target is the depth of the cup added to the breakout level.

This pattern is most reliable on weekly and daily timeframes. For a deeper understanding of how trends support pattern reliability, see our guide on moving averages.
