Keith, He was asking for the smoothing factor, not the period. The smoothing factor is a value between 0 and 1, as described in the document pointed to by his link.
It is a good question. After some brief searching, I could not find the answer. Though, I suppose you could fire up a chart using a short period and do the math, as per the comments of DEMA. http://www.amibroker.com/guide/afl/afl_view.php?id=42 Mike --- In [email protected], Keith McCombs <kmcco...@...> wrote: > > It's settable by you.
