A Hangman Doji like all Doji's require confirmation of the next trading day and cannot be considered by themselves without looking at the volume on the day the Doji hit vs the previous days' trading as well as other indicators such as underlying moneyflow, VWAP and so on. They are cause to look further at other indicators and possibly set stops accordingly if so inclined. As we see today there is more volume and hitting several month old resistance levels. Another thing to look at when a Doji appears is the previous 2 days candles , combine them to see if a bearish or bullish candle emerges. There are no single indicators or candles that stand alone is what I have learned.
