Stochastic RSI (MTF) by Martin Buecker

Multi-Timeframe Smoothed Stochastic RSI Indicator
Author: Martin Bücker

This indicator calculates the Stochastic RSI based on a higher timeframe while running on a lower timeframe chart, providing a smoother and more responsive curve without the typical step-like behavior of higher timeframe data.

Multi-Timeframe Support: Computes the Stochastic RSI using data from a user-defined higher timeframe (e.g., 3-minute on a 1-minute chart) while aligning updates to the current chart's timeframe for timely signals.

Smoothing: Applies smoothing to both %K and %D lines to reduce noise and create smooth curves, avoiding the stair-step effect common in higher timeframe indicators.

Customization: Allows the user to adjust RSI length, stochastic length, and smoothing parameters for fine-tuning.

Visuals: Plots %K and %D lines with clear coloring and highlights overbought/oversold zones with background fills.

This tool is ideal for traders seeking to integrate higher timeframe momentum information into lower timeframe decision-making without losing timing accuracy or smoothness.
