buy or sell Candle as entry signal.

Basically as a form of a confrmation entry. For example I want to use the rsi filter for a system. The ea will buy below 30 rsi. Sometimes the market keeps dipping. As for that it would be nice to add a filter that it will only open the trade when the markets first make a buy candle(the candle must be closed at the desired TF) after the closed candle it will open the trade. Vice versa for a sell. I hope I explained the Idea properly. 

Thanks!
