Created by John R. McGinley, the McGinley Dynamic is a more responsive variant of exponential moving average. [Discuss]
// usage (with Close price) IEnumerable<DynamicResult> results = quotes.GetDynamic(lookbackPeriods, kFactor);
int - Number of periods (
N) in the moving average. Must be greater than 0.
double - Optional. Range adjustment factor (
K). Must be greater than 0. Default is 0.6
Historical quotes requirements
You must have at least
2 periods of
quotes, to cover the initialization periods. Since this uses a smoothing technique, we recommend you use at least
4×N 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.

McGinley suggests that using a
Kvalue of 60% (0.6) allows you to use a
Nequivalent to other moving averages. For example, DYNAMIC(20,0.6) is comparable to EMA(20); conversely, DYNAMIC(20,1) uses the raw 1:1
Nvalue and is not equivalent.
- This method returns a time series of all available indicator values for the
- It always returns the same number of elements as there are in the historical quotes.
- It does not return a single incremental indicator value.
- The first period will have a
nullvalue since there’s not enough data to calculate.
Convergence warning: The first
4×Nperiods will have decreasing magnitude, convergence-related precision errors that can be as high as ~5% deviation in indicator values for earlier periods.

This indicator may be generated from any chain-enabled indicator or method.
// example var results = quotes .Use(CandlePart.HL2) .GetDynamic(..);
Results can be further processed on
Dynamic with additional chain-enabled indicators.
// example var results = quotes .GetDynamic(..) .GetRsi(..);
