Well, then I'm looking forward to many exciting upgrades :-)
I'm always on the quest to find to best, most automated but still
customizable TA tools. I have tested so many in the past 4 years,
that I forgot most of their names. The only ones I work with today
are MetaStock, Omnitrader and now, since a couple of weeks,
Amibroker. Like this one very much, I must admit. Not to the least
because of the direct contact with the developper - a certain TJ ;-)
I'll check these other groups out. Talking tech things is
interesting, but finally, I love it most to trade, not to search for
the holy grail indicator. Beware of paralysis through analysis !
regards
Stefan
