Infact the best rsi setting that i'm using now is 30,50 and 70 level.i use 50 level for entry price while 30 and 70 level is use for a trend reversal.as regards an entry price--when rsi is above 50 level i place a buy order and sell order when the rsi fall below 50 level.Trend reversal---when rsi is above 70 level it is consider an over bought and when rsi is below 30 level is consider an over sold area.so when these two happen a reversal will take place
