A chart pattern is a visual formation created by price movements on a trading chart. Traders use these patterns to predict future price direction based on historical behavior and the psychological dynamics between buyers and sellers.
How chart patterns work
Chart patterns form when price bounces between support and resistance levels, creating recognizable shapes. Two main categories exist: continuation patterns signal an ongoing trend will persist, while reversal patterns suggest the current trend is ending and will change direction.
Common chart patterns
- Head and Shoulders: signals a reversal of an uptrend or downtrend
- Triangles: may indicate continuation or reversal depending on the surrounding trend
- Flags and Pennants: short-term continuation patterns
- Double Top and Bottom: indicate trend reversals
- Cup and Handle: suggests bullish continuation
Practical use and limitations
Traders use chart patterns to identify potential entry and exit points. However, pattern recognition requires experience because interpretation can vary between traders. False breakouts—where a pattern appears to confirm a move but reverses unexpectedly—are also common. To improve reliability, successful traders combine pattern analysis with other technical indicators rather than relying on patterns alone.
