Asymmetrical RSI is an indicator that computes a custom relative strength index from the rate of change of a user-selected source. It plots the resulting ARSI line in a separate pane with color coding that turns green above the overbought level and red below t

RSI Cyclic Smoothed Auto
This indicator applies an RSI-style oscillator smoothed with a cyclic filter, based on the dominant cycle idea from a published trading book.

Source Code
The code stays on GitHub. The author has not published this script under an open licence, so ForexR does not show its code. Copy script reads the file straight from GitHub into your clipboard, so you can still try it on your own chart. Ask the author before reusing the code anywhere else.
Overview
A Fast Fourier Transform library measures cycle strength, and a table lists the strongest cycle periods. The cycle length can be set manually or detected automatically, and vibration and leveling values can also be automatic. It plots in a separate pane, with optional frequency spectrum and filtered time-domain output. The file name warns that it contains bugs.
- Cyclic smoothed RSI
- FFT-based dominant cycle detection
- Table of strongest cycle periods
- Auto or manual vibration and leveling
- Optional power spectrum output

No repainting, lookahead or stacked entries were found in its code or README. That says nothing about how well it works: test it first.

Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints. Check it in the Strategy Tester and on a demo account before you rely on it.
