Name That Pattern: Candlestick & Chart Pattern Game
Pattern field guide · definitions used for scoring
Doji
Open and close are nearly equal: real body ≤8% of the candle’s range.
A doji shows a small real body; it does not establish a future direction.
Hammer
After a ≥1% five-session decline: body 10–32% of range, lower shadow ≥2.2× body, upper shadow ≤18% of range.
A long lower shadow after a decline is the defining context; later bullish confirmation is separate.
Shooting star
After a ≥1% five-session rise: body 10–32% of range, upper shadow ≥2.2× body, lower shadow ≤18% of range.
A long upper shadow after a rise is different from a lower-shadow hammer.
Bullish engulfing
After a ≥1% five-session decline: a green real body contains the previous orange body, is ≥1.2× as large, and is ≥40% of the current range.
The real bodies must engulf, while wicks do not have to.
Bearish engulfing
After a ≥1% five-session rise: an orange real body contains the previous green body, is ≥1.2× as large, and is ≥40% of the current range.
The candle colors and prior direction distinguish this from bullish engulfing.
Double top
Last three confirmed alternating swings: high–low–high; peaks within 2.5%, ≥8 sessions apart, trough ≥4% below the lower peak, prior eight-session rise ≥1%.
Two similar peaks form a candidate shape. A subsequent neckline break is a separate confirmation.
Double bottom
Last three confirmed alternating swings: low–high–low; lows within 2.5%, ≥8 sessions apart, bounce ≥4% above the higher low, prior eight-session decline ≥1%.
Two similar troughs form a candidate shape; a neckline break is not presumed.
Head and shoulders
Last five swings: high–low–high–low–high over ≥14 sessions, shoulders within 3.5%, head ≥4% above both, troughs within 6%, shoulders ≥2.5% above both troughs; prior eight-session rise ≥1%.
The middle peak is higher than both shoulders; the neckline joins the intervening troughs.
Inverse head and shoulders
Last five swings: low–high–low–high–low over ≥14 sessions, shoulders within 3.5%, head ≥4% below both, highs within 6%, shoulders ≥2.5% below both highs; prior eight-session decline ≥1%.
The middle trough is deeper than both shoulders; the neckline joins the intervening highs.
Ascending triangle
Three highs and three lows fit boundaries within 1.2% of mean close. Upper boundary changes ≤1.2%; lower rises ≥2.5% across their common span.
Approximately flat highs and rising lows define the candidate triangle.
Descending triangle
Three highs and three lows fit boundaries within 1.2% of mean close. Lower boundary changes ≤1.2%; upper falls ≥2.5% across their common span.
Approximately flat lows and falling highs define the candidate triangle.
Symmetrical triangle
Three highs and three lows fit boundaries within 1.2% of mean close. Upper falls ≥1.8%; lower rises ≥1.8% across their common span.
Both boundaries converge; the formation alone does not specify a breakout direction.
No clear pattern
No unique match to any named pattern in the selected mode under this game’s thresholds.
This does not mean that every possible technical pattern is absent.

Your accuracy by pattern
How to practice candlestick and chart patterns
Start with candle-pattern mode and inspect the highlighted candle or pair, including the preceding trend. A hammer has a long lower shadow after a decline; a shooting star has a long upper shadow after a rise. An engulfing pattern compares the real bodies of two candles, rather than requiring every wick to be engulfed.
Switch to chart-pattern mode to compare swing highs, swing lows and converging boundaries. Lock your answer before viewing the annotations. The separate future reveal shows what followed; it does not determine whether the visible formation met the game’s criteria.
What does “No clear pattern” mean?
No single named pattern in the selected mode meets the game’s thresholds. These cutoffs make scoring reproducible; they are not universal technical-analysis standards. Recognizing a shape does not establish that its next move will succeed.
