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.

If you are interested in more serious work with the indicator you can upgrade to Pro version. It uses daily/weekly/monthly & intraday data feeds & includes buy/sell signals based on the Chebyshev trend. A unique method has developed specially for app to provide these signals. Trends can also be compared with classical MA & Bollinger Bands, Parabolic SAR, MACD, Volume & Chaikin indicators. Other features include the ability to save stock symbols in a portfolio, keep eye on most recent signals in the group, control indicators' parameters & more!
