A Spinning Top and a Doji are both candlestick patterns that signal market indecision, but they differ in structure and meaning.

A Spinning Top has a small real body located in the centre of the candle, with upper and lower shadows of similar length. This indicates that buyers and sellers were active during the session, but ultimately neither side gained significant control. The open and close prices are close, but not identical. Spinning Tops often appear during consolidations and can signal potential reversals or pauses in a trend.

In contrast, a Doji has an extremely small or non-existent real body, meaning the open and close prices are virtually equal. It strongly reflects indecision or equilibrium between buyers and sellers. Depending on the position and shadow lengths, Dojis are categorized as standard Doji, Dragonfly, Gravestone, or Long-Legged Doji, each with unique implications.

While both patterns indicate indecision, Dojis are generally stronger reversal signals than Spinning Tops due to the perfect balance between opening and closing prices. Traders often look for confirmation from subsequent candles before acting on either pattern. In summary, the key difference lies in the size of the real body and the strength of the indecision they represent.
