Fourier_extrapolator_sin - Indicator for MetaTrader 4

The indicator was created exclusively for the comprehensive market analysis. In its heart is the simple truth that if on the chart there were already 3 waves of the same period, than the probability of the 4th is high. The forecasts are based on the sum of the found harmonics and the larger the start window, the more accurate is the signal, but its processing will take more time.
