RSI Cbot

Hi everyone,

In this Cbot when the RSI last value pass 70 or drop below 30 it open or close the the trade, I need to change it to when the candle stick is closed and then if the RSI value is over 70 or under 30 it open or close the trade.

Also the TP and SL is not working , I would appreciate if someone advice me 

Thanks
