What is Chart Pattern Recognition?
Chart pattern recognition is a fundamental technique in technical analysis that identifies recurring price formations on financial charts. These patterns emerge from the collective psychology of market participants and can signal potential trend reversals or continuations. Our free chart pattern scanner uses algorithmic analysis to automatically detect these formations in your price data, eliminating subjective interpretation and providing objective pattern identification.
Whether you're analyzing stocks, forex, cryptocurrencies, or commodities, chart patterns provide valuable insights into potential price movements. Classic patterns like head and shoulders, double tops and bottoms, triangles, wedges, and flags have been studied for decades and continue to be relevant in modern markets. Our pattern recognition tool calculates confidence scores and historical success rates to help you assess the reliability of each detected pattern.

Chart Patterns We Detect
Head and Shoulders
Classic reversal pattern with three peaks. The middle peak (head) is highest, flanked by two lower peaks (shoulders). Signals trend reversal.
Double Top / Bottom
Two peaks (or troughs) at similar price levels indicate strong resistance (or support). Often precedes trend reversal.
Triangles
Ascending, descending, and symmetrical triangles show price consolidation before a breakout. Direction depends on triangle type.
Bull & Bear Flags
Continuation patterns showing a strong move followed by tight consolidation. Expect breakout in the direction of the prior trend.
Wedges
Rising and falling wedges are reversal patterns. Rising wedges are bearish; falling wedges are bullish despite their direction.
Cup and Handle
Bullish continuation pattern resembling a cup with a handle. The rounded bottom and small pullback signal accumulation before breakout.
