Hello Jan,
JP> I realized that I risked your wrath and a visit to my doctor by giving
JP> my advise to Sarb, however, I VERY RESPECTFULY disagree with
JP> you and stand by my no's which come from MY positive experience.
everyone has a positive experience every now and then. a brilliant
programmer who is on this list once had a equity curve that looked
like a rocket ship. if he could sustain it he would own us all by now.
instead he is programming for a software company now. what happened?
he had a run that's what happened and he was over leveraged expecting
the inverted pyramid to not topple.
JP> BTW, 5 years of data for daytrading would mean something like
JP> 1200 to 5000 trades,
1200 trades is a good number, when you have something that will
sustain profitability over that many trades you have it.
JP> in MHO totally unnecessary and also to some extent meaningless
JP> considering the fact that markets change all the time and a
JP> daytrading system must be, from time to time, adjusted or
JP> redesigned. 5 years ago, Emini was different than it is now and
JP> will be certainly different again in less than 5 years.
if you have the opinion that the markets change and you have to
continually tweak. then i think thats like someone saying driving a
Ferrari is no fun, when in fact they have never driven one. so how
would they know? use the oddball system for example. i checked this
weekend and it has shown 97,100.00 in (hypothetical of course for the
nfa) since its disclosure. i developed the model in 92. the core i
released has not been changed since then and it was developed on the
full contract before the split and before the emini. explain that
away? so i am a firm believer in capturing a markets personality, the
whole personality. its there you just have to discover it.

and like you said this is my personal experience also and your mileage
will very most likely vary well the hell far from mine.

Have a Great Day, Mark
