LaguerreRSI is a technical indicator that applies the Laguerre filter to the traditional Relative Strength Index (RSI) to produce a smoother and faster-reacting oscillator. This approach reduces market noise and lag, enhancing the precision of timing entries and spotting early reversals. The indicator features an adjustable alpha parameter, allowing users to control sensitivity and responsiveness. It can optionally normalize output values to a 0–100 scale, similar to standard RSI, facilitating easier identification of overbought, oversold, and middle reference levels. LaguerreRSI is particularly suited for use in ranging markets or as a confirmation tool during trend pullbacks. Its design aims to provide clearer signals of short-term exhaustion and potential market turning points.
