Kalman Step Signals

The Kalman Step Signals indicator combines Kalman Filtering with Supertrend logic to provide a smoothed trend-following system designed to identify market shifts and price rejections.

Usage

The indicator can be used to identify primary trend directions and specific entry/exit zones. Traders can observe the trend-colored cloud and signals to gauge market momentum.

• Trend Identification: The color-coded Supertrend line and background fill indicate the current trend direction. A green cloud suggests a bullish environment, while a red cloud suggests a bearish one.
• Trend Reversals: Large triangle labels (▲/▼) mark the points where the Kalman-filtered price crosses the Supertrend threshold, signifying a potential trend change.
• Rejection Entries: Small arrows (▲/▼) appear when price tests the trendline but fails to break it, indicating a trend continuation or "rejection" entry.
• Exit Bands: The script plots upper and lower bands that serve as potential exhaustion or take-profit targets relative to the current trend volatility.

Details

This tool leverages a Kalman Filter to smooth price data before applying Supertrend calculations. Unlike traditional moving averages, the Kalman Filter dynamically adjusts to price volatility by balancing responsiveness (Alpha/Beta) and noise reduction. This refined data is then processed through an ATR-based Supertrend formula to create dynamic support and resistance levels. By using smoothed data for the Supertrend logic, the indicator reduces "whipsaw" signals often found in standard trend-following tools.

Settings

Kalman Filter

• Kalman Alpha: Controls the smoothing factor. Smaller values provide more smoothing, while larger values increase responsiveness.
• Kalman Beta: Influences the rate of change sensitivity, helping the filter adjust to trend shifts.
• Kalman Period: Defines the lookback period for the filter calculation.

Supertrend

• Supertrend Factor: The multiplier applied to the ATR to determine the distance of the trend line from the price.
• ATR Period: The period used to calculate the Average True Range for volatility measurement.

Colors

• Bullish Color: Customizes the visual representation of uptrends.
• Bearish Color: Customizes the visual representation of downtrends.

FAQ

How do I use the rejection signals?

Rejection signals are designed for trend continuation trades. When price briefly dips below (in an uptrend) or rises above (in a downtrend) the trendline but closes back on the trending side, a rejection signal is plotted.

Can I set alerts for trend changes?

Yes, the indicator includes built-in alert conditions for both trend changes and rejection entries, which can be configured via the TradingView alerts menu.

How do I access Kalman Step Signals?
