The MACD does the same but expressed in absolute points. Expressing the difference in percentage allows to compare the indicator at different points in time when the underlying value has significatnly different values. Most on-line literature shows the percentage calculation having the long exponential moving average as the denominator. Some sources like MetaStock use the short one.
