hi
why macd <> mov( close, 12, E) - mov( close, 26, E)

Most analysts (including Equis International's) say that the MACD indicator is "the difference between 12-day and 26-day exponential moving averages." However, the indicator is really the difference between 0.15 and 0.075 exponential moving averages (whereas, when expressed in decimal form, the 12- and 26-day exponential moving averages are actually 0.153846 and 0.076923 exponential moving averages). See Moving Average Calculation Methods for more information on exponential moving average calculation methods.
Due to these minor differences in the exponential values, the following formula is slightly different than the predefined MACD indicator. Remember that you can plot the true MACD indicator using the macd() function (see MACD).
mov( close, 12, E) - mov( close, 26, E)
The MACD's trigger (which is a 9-day exponential moving average of the MACD indicator) can be calculated as shown below:
mov( macd(), 9, E)
