Indicators For Scalping, please post here

oh yes guys, i have encountered some problems using candlesticks, to my knowledge candle i have seen in tutorial or books. e.g. they uses intraday examples. therefore, you can see a gap in between the candles. e.g. a evening star there is a gap between the first and second candle, but if i were to use lets say 30 mins frame i cant identify formations. unless it is like hanging man or hammer as there is only 1 candle involve. so what am i suppose to do?
