[Octave-patch-tracker] [patch #8670] macd function for financial package

Follow-up Comment #5, patch #8670 (project octave):

The way you calculate the exponential moving average is wrong. In a N-period
exponential moving average the first n-1 values are blank and the nth value is
the simple moving average of the first n periods and then then you use the
remaining periods' prices from there. Check out the following web page for an
example.
