now I am puzzled. Why would you do this? The first derivative is the change rate. Ok, I would understand one does want to do some smoothing. But the difference between short and longterm EMA certainly isn't the first derivative. It does not seem to be a very good approximation, either.
I can see this is a somewhat bizarre change rate indicator, though. And it might have some merits, if it just works..
