Quote from Gabfly1:
kut2k2, I think you're a very smart guy. But I think you might be missing the point here. Mike Covel and I have had our many differences, but he is right on this one. And, in any case, he was merely quoting Ed Seykota, who very adroitly said, and Covel quoted him, as follows:
"When we speak of trends we are necessarily projecting our own definitions. With that in mind, we can proceed to examine ways to define, compute and use trends."
You cannot argue with this basic observation. I imagine that the "now" part elsewhere in his quote is more of a Zen thing for Mr Seykota, who is perhaps being somewhat pedantic by pointing out that the present is a single moment. A trend requires more than one observation, but there can be only one observation in a singular moment in time. I think the distinction is more a philosophical one than a practical one. In any event, it may actually serve to highlight the fact that our specific and operational definitions of trend are decidedly our own because we all look at the past differently and act upon our individual interpretations.
