Stochastic RSI with crossover-indication and alerts

The Stochastic RSI with crossover-indication and alerts indicator provides an enhanced visualization of traditional Stochastic RSI momentum, specifically identifying key crossovers relative to user-defined threshold levels to pinpoint potential market reversals.

Usage

The indicator is primarily used to identify momentum shifts through crossovers of the K and D lines. Unlike standard oscillators, this tool highlights specific high-probability areas for these crosses:

• Bullish Signals: A green vertical line and cross shape appear when the K-line crosses above the D-line while below a specific threshold (default is 50). This indicates upward momentum starting in a relatively oversold or neutral zone.
• Bearish Signals: A red vertical line and cross shape appear when the K-line crosses below the D-line while above a specific threshold (default is 50). This indicates downward momentum starting in a relatively overbought or neutral zone.

A unique feature of this tool is the Signal Validity setting. Users can choose to keep the signal lines visible for up to three bars. This is useful for traders who consider a crossover valid for entry even if it occurred one or two bars prior.

Details

The script calculates the Stochastic RSI by applying the Stochastic formula to the Relative Strength Index (RSI). It includes smoothing parameters (K and D) to filter out market noise. The primary enhancement involves checking the position of the crossover relative to the "Crossover Limit" and "Crossunder Limit" inputs. By default, these are set to 50, ensuring that bullish crosses are only highlighted in the lower half of the oscillator and bearish crosses in the upper half.

Settings

Stochastic RSI Parameters

• K: Smoothing period for the %K line.
• D: Smoothing period for the %D line (moving average of %K).
• RSI Length: Lookback period for the underlying RSI calculation.
• Stochastic Length: Lookback period for the Stochastic calculation applied to the RSI.
• RSI Source: The price source used for the RSI (e.g., Close, Open, High, Low).

Signal & Visuals

• # valid bars: Determines how many subsequent bars the crossover/crossunder signal remains visible on the chart (1 to 3 bars).
• Line Width: Adjusts the thickness of the vertical signal lines.
• Crossover Limit: The level below which a bullish crossover (K crossing over D) must occur to trigger a signal.
• Crossunder Limit: The level above which a bearish crossunder (K crossing under D) must occur to trigger a signal.

FAQ

How do I use the signal validity feature?

By adjusting the "# valid bars" setting, you can extend the visual highlight of a crossover for up to three bars, allowing you to see if a recent momentum shift is still within a tradable window.

Can I change the sensitivity of the signals?

Yes, you can adjust the "Crossover Limit" and "Crossunder Limit" settings. For example, setting these to 20 and 80 respectively will only highlight signals that occur in extreme overbought or oversold conditions.

How can I access this tool?
