A single candlestick is a four-number story: open, high, low, and close. Its shape tells you who won the period, buyers or sellers. The body measures conviction, the distance from open to close, and not trading volume. The shadows map rejection: a long upper wick means higher prices were pushed back, a long lower wick means lower prices were bought back up. Named shapes like the doji, spinning top, marubozu, hammer, hanging man, shooting star, and inverted hammer are useful shorthand, but identical shapes can flip meaning depending on the trend around them. The hard truth, confirmed by Thomas Bulkowski's testing across decades of data, is that most single candles perform near a coin flip, around 60% or worse. One candle is a hint, not a signal. It only becomes usable information when you add three layers of context: prior trend, location at support or resistance, and confirmation from the sessions that follow.

How to Read a Candlestick: What a Single Bar Is Actually Telling You

Almost everyone reads candlestick charts. Almost no one knows where they came from. This piece traces the real history. The West built its own tools first: the 1867 stock ticker, tape reading, Dow Theory, and the OHLC bar chart. Japan took a different path at Osaka's Dojima Rice Exchange, formally authorized in 1730, where a margined rice futures market became the candle's true birthplace. Legend credits trader Munehisa Homma with inventing the chart in the 1700s. He was real and brilliant, but the record does not back the claim. Analyst Steve Nison, who brought candlesticks west in 1989, argues the chart more likely emerged in the late 1800s, decades after Homma died. The candle's edge is its colored body, showing at a glance whether buyers or sellers won. The article also covers three variants: Heikin-Ashi, Renko, and Kagi. The bigger lesson is a skill: telling documented fact from trading folklore.
