First, calculates the fast moving average (usually 12 days) and slow moving average (usually 26 days) by exponential calculation method; second, make fast line value minus slow line value to gain the difference of relative distance. In order to make the trend signals more clear and less influence exerted by of excessive price fluctuation, the difference should be smoothly calculated (general elect 9 days) to get average of difference value. Chart the difference and its average in a coordinate with time for horizontal axis and MACD for vertical axis. Then we can apply the identical, contrary or cross signals through observing their direction, relative and absolute positions.
