A Polynomial-Extrapolated Sine Indicator for MT5

Summary

This brief description outlines an MT5 indicator that constructs a moving line by extrapolating a fourth-degree polynomial. It describes deriving candidate lines from a sine-like curve and from an axial or nearly constant line, with different line-power settings also intended to represent an inclined straight line. A value is removed from the constructed curve and a line of extrapolated values is plotted without redrawing, according to the description.

The indicator exposes parameters for polynomial degree, leverage, multiplier, output shift, and interval. The multiplier controls which reference curve or mirrored curve supplies the removed value, while interval scales the averaging leverage. The document does not define precise equations, give chart examples, explain signal interpretation, or provide performance or repainting tests. It is therefore a conceptual description of an indicator rather than a validated trading method; users would need to inspect the implementation and test its behavior before relying on it.

Key ideas

• The MT5 indicator plots extrapolated values based on a fourth-degree polynomial.
• Its construction combines sine-like and axial reference lines.
• Parameters control polynomial degree, leverage, curve selection, output shift, and interval scaling.
• The description gives no trading rules, empirical results, or implementation details sufficient to validate the indicator.
