Polynomial and Sinusoidal Extrapolation for a Non-Redrawing Indicator

Article MQL5 code base

Summary

This MT4 indicator description outlines a method for projecting a price-related line. It first builds a sliding line through polynomial interpolation of degree four, then models an extrapolated segment with a sinusoid and an axis that is either near a constant level or an inclined straight line. The description says that one value is removed from each bar’s sinusoid and axis to construct an extrapolated series that does not redraw.

Several inputs control the projection: a leverage setting for removing values from the shifted line, a multiplier that blends or selects among the axis, sinusoid, and mirrored sinusoid, an output offset, and a multiple-averaging interval. The document provides a conceptual description of the indicator and its controls, but no formula details, chart examples, trading rules, backtest results, or evidence of predictive value. Its usefulness therefore lies mainly in explaining the construction idea; the reliability and behavior of the indicator cannot be assessed from the text alone.

Key ideas

  • The indicator uses fourth-degree polynomial interpolation to construct a sliding line.
  • It extrapolates using a sinusoid and an axis that can be constant or inclined.
  • The method removes a value from each bar to build a series described as non-redrawing.
  • Inputs control value removal, blending, output offset, and averaging interval.
  • The description supplies no performance evidence or explicit trading rules.
