Formula

McGinley Dynamic indicator is calculated by the formula:


MD_i = MD_{i-1} + \dfrac{close - MD_{i-1}}{k \times N \times \left(\dfrac{close}{MD_{i-1}}\right)^4}

where

\operatorname{MD_i} is the current McGinley Dynamic;

\operatorname{MD_{i-1}} is the previous McGinley Dynamic;

\operatorname{k} is a constant equaled to 0.6 (60% of a selected moving average period N);

\operatorname{N} is the moving average period;

\operatorname{close} is the closing price.

Usage

In Place of Simple Moving Average

McGinley Dynamic indicator may be used exactly as Simple Moving Average or Exponential Moving Average.

Behavior Comparing Moving Averages

Unlike moving averages such as Simple Moving Average or Exponential Moving Average, McGinley Dynamic avoids of most whipsaws and it rapidly moves up or down according to a quickly changing market. It needs no adjusting because it is dynamic and it adjusts itself.
