Chebyshev Trend Pro - G ed.

The app is similar to ChebyshevTrendPro but fully based on IEX data feeds provided. The current version of app is focused on various intraday (1minute-30minutes) intervals.
The app uses Chebyshev polynomials to create trend lines against IEX intraday 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.
The app includes buy/sell signals & S/R lines based on the Chebyshev trend. An unique method has developed specially for app to provide these signals.
Trends can also be compared with classical MA, Bollinger Bands, Parabolic SAR & volume indicators, MACD, Chaykin & BB%B oscillators and more (check v.2 manual appendix #2 at the support site for more details);.
Other features include the ability to save stock symbols in a portfolio by groups of interest and adjust the trend dates, moved crosshair & Fibonacci retracement.
You can try ChebyshevTrendLite, a free version of the app or or Chebysev Trend Pro IEX ed. for 30 days trial, to test before making a decision to purchase GTrend.
As soon as stock data is sourced from the IEX website, only stocks available on the website can be trended in the app.
A data connection is required to access the IEX website, however the app will perform best if a WiFi internet connection is available.
