RSI with SMA and Bollinger Bands
The SMA and BB use the RSI as a source. The source of the RSI is selectable.
With the right settings, you can effectively determine the trend phase and trend strength.
I personally use the following settings:
RSI with a 14-period applied to Price Close.
The SMA has a 26-period, and the Bollinger Bands have a period of 50 with a deviation of 2.
