RSI MA Arrow needed Quickly

Hi there, I would like a simple arrow built please, RSI has to cross over 70 or 30 then come back across a MA on itself to show an arrow up Green or down Red

Then when the RSI touches the opposite  I would like a Symbol to Exit the trade like these pics https://www.screencast.com/t/n3hQoeQW

So over 70 then cross RSI MA  down = sell RED arrow 

under 30 then cross RSI MA  down = Buy Green arrow 

After buy or sell alert next touch of RSI level gives either Green tick if pips are positive from our signal or red cross if negative from our signal arrow 

no RSI touches levels and ma etc during candle form so must only calculate on candle close so as to not repaint. 

I would like this built very fast so don't apply if u can't build quickly
