chart for Tillson T3 Moving Average

// C# usage syntax
IEnumerable<T3Result> results =
  quotes.GetT3(lookbackPeriods, volumeFactor);


lookbackPeriods int - Number of periods (N) for the EMA smoothing. Must be greater than 0 and is usually less than 63. Default is 5.

volumeFactor double - Size of the Volume Factor. Must be greater than 0 and is usually less than 2. Default is 0.7

Historical quotes requirements

You must have at least 6×(N-1)+100 periods of quotes to cover the convergence periods. Since this uses a smoothing technique, we recommend you use at least 6×(N-1)+250 data points prior to the intended usage date for better precision.

quotes is a collection of generic TQuote historical price quotes. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.



Convergence warning: The first 6×(N-1)+250 periods will have decreasing magnitude, convergence-related precision errors that can be as high as ~5% deviation in indicator values for earlier periods.


Date DateTime - Date from evaluated TQuote
