Multi-Timeframe Stochastic RSI

Inputs for Stochastic RSI:

The script takes three sets of user-defined inputs for constructing three Stochastic RSI indicators, allowing the user to modify:
Length of the Stochastic RSI.
Smoothing parameters for both the %K and %D lines (K and D are the two components of Stochastic RSI).
Colors for each Stochastic RSI line.
Timeframes for the second and third Stochastic RSI indicators (daily and hourly, respectively).
Calculation of Stochastic RSI:

The Stochastic RSI is calculated in the script using:
ta.rsi() to compute the RSI of the price.
ta.stoch() to apply the Stochastic formula on the RSI values.
ta.sma() to smooth %K and %D lines as per the given length inputs.
The request.security() function is used to fetch the RSI values for the specified timeframes (higher timeframes).
Plotting:

The calculated %K lines from the three strategies are plotted on the chart in distinct colors.
A simple moving average (SMA) of the primary Stochastic RSI (%K line) is computed and plotted in yellow for additional clarity.
Overbought (80) and Oversold (20) levels are defined and displayed as dashed horizontal lines.
Cross Signals (Commented Out):

Bullish and bearish cross signals are defined based on crossovers between %K and %D lines but are not plotted visually by default. There is commented-out code available to visualize these signals if desired.
Additional Points
Utility: This indicator gives traders a multi-faceted view of market momentum across different timeframes. For example:
Trading strategies might rely on observing if the current timeframe's Stochastic RSI aligns with signals from higher timeframes.
Overbought and oversold levels help identify potential reversal points.
Example of Interpretation
If the short-term Stochastic RSI is rising (crossing above the %D line) while both higher timeframes show that they are within oversold conditions, it might signal a strong buying opportunity.
Customization
The script includes several customizable parameters making it adaptable to different trading styles and asset classes.
Users can easily modify lengths, colors, and timeframes to fit their analysis preferences.
Conclusion
This Multi-Timeframe Stochastic RSI indicator is a powerful tool for traders who want to combine momentum analysis from multiple timeframes.
