I say let grownups be grownups and not worry about people following
the wrong guru, or that their trading fees go up. They can use it for
a small proportion of their portfolio, or follow an impeccable guru
such as an ivy league university endowment manager. I believe Yale
endowment trades are quickly provided to students who want to emulate
it, although not automatically. I would hope a brokerage could set up
a small-delay pipeline funded simply by their motive to increase trade
frequency.
But the practical problem seems to be extortionate advisor fees in the
current implementations. They only mentioned one brokerage I
recognized, and I can't see any mention of autotrade on TDameritrade
site. A deeper google dredges up a trading partner site where you have
to link autotrade to an expensive newsletter

. And to save wallowing thru a score of free newsletter trials, you
perhaps have to buy a newsletter that rates newsletters?
