A single Doji candlestick doesn't stand alone as a reversal signal. Here's why this matters for traders: the Doji's indecision pattern requires validation from the next trading session. Without that follow-up confirmation, you risk acting on incomplete market data. Smart traders wait for the day after to see how price responds—does it break above resistance or retreat? That confirmation candle tells the real story. Whether you're analyzing Bitcoin, altcoins, or any trading pair on the spot or futures markets, this rule applies universally. Patience beats rushing into positions based on isolated signals. The confirmation principle keeps you aligned with actual trend reversals rather than false breakouts.
