Inverted Hammer Complete Guide
What is Inverted Hammer?
The Inverted Hammer is a single-candle bullish reversal pattern that appears at the bottom of a downtrend. Visually, it is characterized by a small real body—either green (bullish) or red (bearish)—located at the lower end of the price range, with a long upper shadow and little to no lower shadow. According to Steve Nison, the pioneer of Japanese candlestick charting, the upper shadow should be at least twice the height of the real body to be valid. The formation represents a period where bears initially controlled the trend, but bulls staged a significant intra-day rally. Although the price retraced to close near the lows, the spike in price indicates that buying pressure is beginning to test the resolve of the sellers. From a technical perspective, Thomas Bulkowski’s research in the 'Encyclopedia of Candlestick Charts' indicates that the Inverted Hammer acts as a bullish reversal 60% of the time in a bull market, though it ranks relatively low in overall performance compared to more complex patterns. Bulkowski notes that the pattern's reliability increases significantly when accompanied by high trading volume on the day of the hammer or a gap up on the following day. Crucially, this pattern requires confirmation. A single Inverted Hammer is not a buy signal on its own; traders look for the subsequent candle to close above the Inverted Hammer's body or for a gap up. Historically, the pattern has a 'break-even failure rate' of approximately 35% in bull markets. While it signals a potential floor, its high frequency means it often produces false signals in volatile markets. Therefore, it is best used in conjunction with oscillators like the RSI or at established support levels.
Identification Rules
- The candle must appear after a clear downward price trend.
- The upper shadow must be at least two times the length of the real body.
- ローソク足の実体は、レンジの下端に位置し、色は副次的要素であるが、緑色が好ましい。

FAQ
逆ハンマーにおいて、実体の色は重要ですか？
パターンは、赤または緑のローソク足のいずれでも有効ですが、緑（強気）のローソク足の方が、買い方が終値を押し上げたことを示すため、より強力であると考えられています。Bulkowskiのデータによると、緑のローソク足の方がわずかに成功率が高いことが示唆されています。
インバーテッドハンマーとシューティングスターの主な違いは何ですか？
They look identical, but their context differs. An Inverted Hammer occurs at the bottom of a downtrend and signals a bullish reversal, while a Shooting Star occurs at the top of an uptrend and signals a bearish reversal.
取引を開始する前に、どの程度の確認が必要ですか？
Technical analysts recommend waiting for the next bar to close above the Inverted Hammer's high. According to historical data, waiting for confirmation reduces the failure rate from 35% to significantly lower levels.
What does a very long upper shadow indicate?
非常に長い上影は、日中の大幅な安値拒否を示唆します。しかし、極端に長い場合、上値の抵抗が依然として強く、持続的な反転には至らない可能性を示唆するかもしれません。
Is the Inverted Hammer reliable in all market caps?
It tends to be more reliable in high-volume, large-cap stocks. In low-liquidity penny stocks, the long upper shadow is often just noise or a 'pump and dump' rather than a structural trend reversal.
