Chart patterns explained

A chart pattern is a recognizable shape in a price chart that traders use to frame what buyers and sellers may do next. Patterns are probabilities, not promises — many fail, and context matters.
Reversal patterns
Reversal patterns suggest a prevailing trend may be losing steam.
- Head and shoulders. Three peaks with the middle highest. A break below the "neckline" connecting the lows is the classic signal that an uptrend may be ending. The inverse version appears at downtrend lows.
- Double top / double bottom. Price fails twice at roughly the same level. A double bottom looks like a "W" and a double top like an "M".
Continuation patterns
These suggest a pause inside a trend, after which the trend may resume.
- Flags and pennants. A sharp move followed by a brief, tight consolidation that slopes against the trend (flag) or narrows (pennant).
- Triangles. Ascending (flat top, rising lows), descending (flat bottom, falling highs) and symmetrical forms. Price is compressing toward a decision point.
- Cup and handle. A rounded bottom followed by a small pullback, popularized in growth-stock investing.
How traders try to confirm a pattern
- Volume. Breakouts that come with higher-than-normal volume are often treated as more convincing than those on thin volume.
- The break itself. A pattern is not complete until price actually moves through its key level. Early guesses are the most common mistake.
- The bigger trend. A bullish pattern inside a long downtrend deserves extra caution.
- Risk planning. Decide in advance where the pattern would be proven wrong, and how much you are willing to lose if it is.
Why patterns fail
Patterns are subjective: two traders can draw the same chart differently. News, earnings and broad market moves can override any shape. Treat patterns as a way to organize your thinking, and test any approach on past data or in a paper account before risking money.
