AN MACD VARIATION by Technical Analysis, Inc.
The method used is a variation of the original moving average convergence/divergence (MACD) indicator.
Longer-term exponentially smoothed moving averages (EMA) have been used in the calculation of the
MACD. The new smoothing constants a are 0.0299 and 0.0589, which approximate a 66-week simple
moving average and a 33-week simple moving average, respectively.
