Chart Patterns: The Complete Trading Guide
These formations take weeks to build, and they show you how supply and demand finally resolve. Each one gives you a measured target. More usefully, each one gives you the level that proves it 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 big enough that building a position takes them time. It's 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 has real consequences for how you trade them.
- 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, not a turn. Flags, pennants, triangles, rectangles.
Continuation patterns are generally the more dependable group, for a straightforward reason: all they need is for the existing trend to keep doing what it's already doing. A reversal pattern asks the market to change its mind, and that's a much 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, not 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.
Head and Shoulders Pattern: Rules, Target and Stop
Three attempts by buyers, each weaker than the last. The right shoulder failing to reach the head is the whole signal, and everything before it is an ordinary uptrend.

Double Top and Double Bottom: Rules and Targets
Two attempts at the same level, both rejected. Until price closes beyond the interim high between them, this and a downtrend that simply bounced twice look identical.

Bull Flag Pattern: How to Trade the Pause
The flag is the easy part to see and the wrong part to focus on. What matters is the move that came before it and whether the pullback stays orderly.
Chart Patterns FAQs
What are chart patterns?
Chart patterns are formations price traces out over days to months while supply and demand work themselves out. Because they develop across many sessions, they describe a sustained shift in positioning, which is a bigger thing than one session of activity.
Which chart patterns are the most reliable?
Continuation patterns resolve as expected more often, so flags, pennants and ascending triangles inside an established trend. All they need is for the trend to keep doing what it's already doing. Reversal patterns ask the market to change its mind, which is a much 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 that as a rough expectation, and always check whether real support or resistance sits closer.
Do chart patterns still work?
They still describe real supply and demand, because they're just a way of drawing price. What's changed is how widely known they are, so trading them mechanically has little edge. Their real use is showing you where your thesis breaks, and that's what makes position sizing possible.
What timeframe is best for chart patterns?
Daily and weekly charts. A pattern that takes six weeks to build on a daily chart is a real accumulation or distribution process. The same shape on a 5-minute chart forms in an hour and usually means nothing.
