Hi Steve,

Yes, that is the same as having the price cross the long EMA.

As to why, I can't remember since it was implemented so long ago.

I think it had to do with Don Carlson suggesting it, but I'm not 100% sure of that -- perhaps Don can comment if he remembers (in earlier versions of AI I recall having the short EMA as 20 days and by SP 7 I'd changed it to 1 day).

One thing that I do recall is that using the 1 day short significantly improved general results. So that's why it is in the latest version of AI.
