The bearish Doji Star forms after an uptrend when a long bullish candle is followed by a doji, a candle whose open and close are nearly equal, that gaps above the first candle's body. The doji shows that the buying momentum has stalled and the market is undecided, so the pattern warns of a possible top; traders wait for a bearish candle on the next bar, which would complete an Evening Doji Star.
