Candles are presented to beginning traders as a way to beat the market with all their patterns. ---They are no advantage whatsoever and in fact add other ways for the trader to be wrong with their interpretations. Look at them if you wish, but they are better off discarded.
I agree that candle patterns are BS....when I look at candles vs bars I see the same stuff but candles appear a bit clearer to me but it has nothing to do with engulfing bear clouds or whatever else they peddle.
If you use candles by themselves, you will lose money eventually when a pattern fails. Use them properly, and you get perfect entries with tiny risk. To each their own.
