Fourier-Based Sinusoidal Approximation Indicator and Its Repainting

Summary

Linear Sinus FT is described as a currency-quote indicator that approximates sinusoidal waves and visualizes a Fourier series. The document provides only this high-level description; it does not explain the calculation, parameter choices, signal interpretation, or any trading rules. It therefore introduces the indicator’s mathematical framing without enough detail to reproduce or evaluate its method.

A key limitation is that the indicator redraws its values across all bars whenever the current bar changes. Historical plots can consequently change as new prices arrive, making past signals unstable and complicating chart interpretation or backtesting. The document offers no performance evidence, examples, or comparison with other methods, so it does not establish predictive value or suitability for a trading strategy.

Key ideas

• The indicator approximates sinusoidal waves in currency-pair quotes.
• It visualizes a Fourier-series representation of price data.
• Its values redraw across historical bars whenever the current bar changes.
• The document gives no calculation details or evidence of trading performance.
