Stochastic Expansion Oscillator: Calculation and Signal Line

Summary

The document describes a stochastic expansion oscillator as a variation on the conventional stochastic oscillator, with a distinct calculation and display. It identifies three inputs: the %K lookback period, a slowing period, and a noise filter period used for the signal line. The oscillator value is formed by adding two terms based on smoothed distances from the close to the period’s high and low; the signal is a simple moving average of that combined value.

The description defines the intermediate high and low distances using the highest and lowest prices in the %K window, then smooths them over the slowing period. It provides the calculation structure but no plotted examples, trading rules, parameter recommendations, or performance tests. As a result, it explains how the indicator is constructed but does not establish whether it predicts price movements or how it should be used in a strategy.

Key ideas

• The indicator combines two terms derived from the close’s distance to the period high and low.
• The %K period sets the range used to find the highest and lowest prices.
• A slowing period smooths the high and low distance series.
• A simple moving average over the noise filter period forms the signal line.
• The document gives no trading rules or performance evidence.
