Cyclic Smoothed RSI Indicator

The cyclic smoothed RSI indicator is an enhancement of the classic Relative Strength Index (RSI). The cyclic smoothed RSI indicator was first introduced in the book "Decoding the Hidden Market Rhythm Part 1: Dynamic Cycles" (LINK) and the indicator code has been made public for different charting platforms.

It helps to avoid the noisy signal of the RSI with static oversold/oversold areas, usually leading to many false trade signals and thus to many whipsaw trades. The csRSI therefore provides a much cleaner, zero-lag signal line with adaptive bands to help identifying better trade signals.
