Chebyshev Trend uses Chebyshev polynomials to create trend lines against Yahoo Finance daily stock charts. This innovative trending method is based on creating polynomials using a modified Gaussian least squares fit that essentially acts as a noise filter, removing random fluctuations from the chart data and finds the real underlying trend. The main benefit of using this trending method is an almost complete absense of lag, when compared to moving average trends.
