# Cyclic Smoothed RSI Indicator The **cyclic smoothed RSI** indicator is an enhancement of the classic Relative Strength Index [(RSI)](https://www.tradingview.com/scripts/relativestrengthindex/). The cyclic smoothed RSI indicator was first introduced in the book "Decoding the Hidden Market Rhythm Part 1: Dynamic Cycles" ([LINK](https://www.whentotrade.com/book-part1/ "WhenToTrade Book Dynamic Cycles smoothed RSI indicator")) 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. ##### Advanced Features - Signal and dynamic oversold/overbought calculation according to the dominant cycle length to keep the signal line better in sync with the current market cycle - Ultra-Smooth indicator signal without additional lag (zero-lag indicator) - Adaptive bands to better adjust oversold/overbought areas to market phases (trending/cycling) - Better divergence detection to spot strong signals For more information, please read the referenced book Chapter 4 "Fine tuning technical indicators".
