Using Kalman Filter Speed as an Oscillator with a Smoothed Signal Line

Summary

This brief indicator note proposes treating the speed, or possibly the correction factor, of a Kalman filter as an oscillator. It adds a smoother signal line formed from a moving average of that speed series. The signal line can be shifted by a configurable number of bars, and the indicator’s output buffers are named to clarify what each represents.

The post frames the idea as an experiment rather than a validated trading method. It gives no precise equations, parameter values, entry or exit rules, chart examples, backtest results, or asset context. Consequently, readers can learn the general construction concept—derive an indicator from a filter’s changing adjustment behavior and smooth it for comparison—but cannot assess its predictive value or reproduce a complete strategy from this description alone. Any use would require specifying the filter, testing parameter choices, and evaluating the indicator across market conditions.

Key ideas

• The proposed oscillator uses the speed or correction behavior of a Kalman filter.
• A moving average of the speed series serves as a smoother signal line.
• The signal line may be shifted by a configurable number of bars.
• The post describes an experiment and supplies no evidence of trading performance.
