Description
Akin to the Stochastic Oscillator, the Stochastic RSI is a technical indicator which oscillates according to change in the RSI (rather than price). It works by taking a moving average of the cumulative changes in the RSI over a given time period. The K% line is a series of values calculated by the formula:
100 x (current close - max. of RSI in given period) / (max. - min. of RSI in given period).
The D% line is a moving average over a given period of the K% line, which results in a smoother, less sensitive curve. A popular strategy is trading the crosses between the K% and D% lines according to the current market sentiment.
This is slightly different to qualitiedx2's versions (#1 and #2) of the Stochastic RSI, which are unfamiliar to me - please do let me know if I've given this an incorrect title. My implementation is similar to that described here and here (like the one on TradingView's platform).
Changelog:
27/08/2022 - added missing getters and setters to attributes.
28/08/2022 - removed deprecated 'PersentsK' and 'PersentsD' and implementation of the StochasticOscillator interface. Added cloud. Fixed code style. Added indicator attributes.
For scalping on very short timeframes (<M5), it is recommended to use a Stochastic Length of '8'.
