Schaff Trend Cycle

Created by Doug Schaff, the Schaff Trend Cycle is a stochastic oscillator view of two converging/diverging exponential moving averages. In other words, it’s a Stochastic Oscillator of Moving Average Convergence / Divergence (MACD). [Discuss] 💬

chart for Schaff Trend Cycle

// C# usage syntax
IEnumerable<StcResult> results =
  quotes.GetStc(cyclePeriods, fastPeriods, slowPeriods);


cyclePeriods int - Number of periods (C) for the Trend Cycle. Must be greater than or equal to 0. Default is 10.

fastPeriods int - Number of periods (F) for the faster moving average. Must be greater than 0. Default is 23.

slowPeriods int - Number of periods (S) for the slower moving average. Must be greater than fastPeriods. Default is 50.

Historical quotes requirements

You must have at least 2×(S+C) or S+C+100 worth of quotes, whichever is more, to cover the convergence periods. Since this uses a smoothing technique, we recommend you use at least S+C+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 S+C+250 periods will have decreasing magnitude, convergence-related precision errors that can be as high as ~5% deviation in indicator values for earlier periods.
