Here is Advanced RSI Helper. An advanced RSI represented in a candle type chart. It contains a Stochastic and a Pivot Detector (High-Low) and RSI divergences.
It also contains a Filter which you can configure the upper, lower zone to colorize the bars on the chart only when you are overbought or oversold, when you are in range the bars appear "transparent".
You also have the option of placing alerts for divergences or when the rsi exceeds the upper zone 1 / 2 or lower zone 1 / 2.
if you encounter any bugs do not hesitate to let me know in the comment area. The same goes for your suggestions.
Cheers and remember, risk management is the most important!
