You should not always trade the doji because it signals indecision rather than direction, and produces too many false signals when traded in isolation. On their own, dojis are not much help in making sound, high-probability trading decisions, mainly because even if a doji signals the beginning of a reversal, it gives no indication of how far the reversal may go or how long it may last
. Trade it only when it forms at meaningful support or resistance, aligns with the broader trend, and gets confirmed by the next candle.
