Chart Patterns: The Complete Trading Guide
Multi-week formations that describe how supply and demand resolve. Each one gives you a measured target and, more usefully, a level that proves the pattern wrong.
A chart pattern is a formation price traces over weeks or months while supply and demand work themselves out. Where a candlestick pattern describes one or two sessions, a chart pattern describes a process.
That difference matters. A multi-week formation represents sustained accumulation or distribution by participants large enough to need time to build a position. It is harder to fake and harder to produce by accident.
The two families
Every pattern in this section belongs to one of two groups, and the distinction is practical rather than academic.
- Reversal patterns form at the end of a trend and suggest it is turning. Head and shoulders, double and triple tops and bottoms, rounding bottoms.
- Continuation patterns form inside a trend and suggest a pause rather than a turn. Flags, pennants, triangles, rectangles.
Continuation patterns are generally the more dependable group for a straightforward reason: they only require the existing trend to keep doing what it is already doing. A reversal pattern asks the market to change its mind, which is a considerably higher bar.
What makes a pattern work
The shape is the least important part. Four things decide whether a formation means anything:
- Volume. It should contract as the pattern forms and expand decisively on the breakout. A breakout without volume expansion is price drifting through a thin order book, and it reverses far more often.
- Duration. A pattern that takes six weeks carries more weight than one that takes three days, because more participants built positions inside it.
- The preceding trend. A reversal pattern needs something to reverse. A "head and shoulders" in a sideways range is three bumps.
- A close rather than a poke. Breakouts are confirmed by a close beyond the boundary. Intraday wicks through a level happen constantly and mean very little.
How to use these guides
Each guide follows the same structure: how the pattern forms and what the order flow behind it looks like, the identification rules, how to measure a target, where the stop belongs, and the conditions under which the pattern fails.
Read them alongside support and resistance, because almost every pattern boundary is a level, and pair every setup with position sizing before taking a trade.
Chart Patterns FAQs
What are chart patterns?
Chart patterns are recognisable formations that price traces out over days to months as supply and demand resolve. Unlike single candlesticks, they develop over many sessions, which means they describe a sustained shift in positioning rather than one session of activity.
Which chart patterns are the most reliable?
Continuation patterns (flags, pennants and ascending triangles in an established trend) tend to resolve as expected more often than reversal patterns, because they only require the existing trend to continue. Reversal patterns ask the market to change direction, which is a higher bar.
How do you measure a target from a chart pattern?
Most patterns use the height of the formation projected from the breakout point. A head and shoulders with a $12 gap between the head and the neckline projects roughly $12 below the neckline. Treat it as a rough expectation rather than a promise, and always check whether real support or resistance sits closer.
Do chart patterns still work?
They still describe real supply and demand, because they are simply a way of drawing price. What has changed is that they are widely known, so trading them mechanically has little edge. They work best as a framework for identifying where a thesis is invalidated, which is what makes position sizing possible.
What timeframe is best for chart patterns?
Daily and weekly charts. A pattern that takes six weeks to form on a daily chart represents a genuine accumulation or distribution process. The same shape on a 5-minute chart forms in an hour and is far more often noise.
