Description
The Volume-Weighted MACD Histogram is from the October 2009 issue of 
Stocks & Commodities magazine.  The author, David Hawkins, presents a novel way to combine both volume and exponential weighting on a moving average and then extends it to the MACD histogram. He claims that it results in the MACD Histogram becoming a better leading indicator.
