Overview

The function blends between minimum, mid, and maximum color points based on an input value. It applies the function to the RSI indicator and plots the resulting line three times on the price chart with varying line widths and color schemes transitioning from red through yellow to lime.

Risk Notes

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.
