What is a candlestick pattern?

A candlestick pattern is a shape formed by one or more candlesticks (OHLC bars) on a price chart. Each candle has an open, high, low, and close; the body is the range between open and close, and the wicks (shadows) show the high and low. Patterns like Doji, Hammer, Engulfing, and Morning Star are used in technical analysis to suggest potential reversals or continuations. This tool checks your OHLC data against predefined rules and returns the pattern name and description.

How to use this candlestick pattern recognizer

  1. 1

    Enter OHLC data

    Paste or type your candle data: one line per candle, each line with Open, High, Low, Close (space or comma separated). Oldest candle first.

  2. 2

    Get pattern results

    The tool evaluates the last candle for single-candle patterns, the last two for two-candle patterns, and the last three for three-candle patterns. Matched patterns appear with name, signal (bullish/bearish/neutral), and description.

  3. 3

    Use in context

    Patterns are not guarantees. Use them with trend, volume, and other indicators. For automated detection on charts, consider building a Pine Script indicator with Pineify.

Why use a candlestick pattern recognizer?

A recognizer gives you consistent, rule-based pattern names from OHLC data so you can screen backtests, compare timeframes, or feed results into other tools. This one runs entirely in the browser—no server, no sign-up. For live charts and custom logic, combine it with Pineify's Pine Script generator to code your own pattern alerts and scans.

Patterns detected

Single-candle: Doji, Hammer, Inverted Hammer, Shooting Star, Hanging Man, Spinning Top, Bullish and Bearish Marubozu. Two-candle: Bullish and Bearish Engulfing, Tweezer Tops and Bottoms, Piercing Line. Three-candle: Morning Star, Evening Star, Three White Soldiers, Three Black Crows. Criteria use body and shadow ratios; results depend on the last 1–3 candles in your input.
