The 20 chart patterns PatternX detects
At a glance
PatternX detects 20 classic chart patterns — head and shoulders, double and triple tops and bottoms, triangles, wedges, flags, pennants, rectangles, cup and handle and rounding patterns — with fixed, rule-based detectors on 8 timeframes from 1 minute to daily, across crypto, US stocks, ETFs and FX.
Each page below explains one pattern from first principles — anatomy, identification, confirmation, invalidation, volume, false signals and example logic — and then shows exactly how PatternX detects it: the swing points, tolerances, breakout rule, stop and target. Detection is deterministic: the same candles always produce the same result, in PatternX Classic and PatternX AI alike. How setups are then scored is in the PatternX Score.
