Laguerre RSI is a technical indicator based on John Ehlers' Laguerre Filter designed to reduce the noise commonly found in traditional Relative Strength Index (RSI) calculations. It allows users to adjust the alpha coefficient to control the lag and smoothness of the indicator, tailoring its responsiveness to market conditions. The indicator generates buy signals when the Laguerre RSI crosses upward above the 20 level and sell signals when it crosses downward below the 80 level. Additionally, a flat reading above 80 indicates a strong uptrend, while a flat reading below 20 signals a strong downtrend. This indicator is used to identify trend strength and potential entry and exit points by filtering out market noise inherent in standard RSI measurements.
