This indicator will allow you to see overbought and oversold areas of the rsi or the cci, you must set yourself the upper and lower band of the rsi (70-30) or cci (100, -100). By default, it's Rsi I have already posted the same indicator but only with the Rsi, I wanted to posted a more complete that offers the 2.
On the chart, it is the overbought / oversold area of the Cci that is displayed
