RSI with Smoothing and over-areas colored ARROWS BUY SELL

This is a complementary script for my previous RSI indicator

You have a BUY and SELL signals here and 3 methods of their interpretations:
- indicator is leaving the over-bought/sold areas
- indicator is entering the over-bought/sold areas
- indicator changes its direction from falling to rising and vice versa

Now you can manually set the values for over bought/sold areas (default is 70 and 30).
