Mark:
Slamming an individual for giving a straightforward and instructive answer
is certainly not admirable by any nor is it conducive to free exchange of
information in a group. Let go of some of your anger and preconceived ideas
about some of our fellow members. If they deserve an attack, I am sure you
will not hold back, but to body slam verbally, an individual for no reason
except who he is, is a defenseless tactic meant to intimidate former
competitors and people-please your friends. I do not think they are
impressed, Mark. I like you and respect you, but this kind of attack is not
wanted by anyone here, I suspect. Try writing an angry letter, and then not
sending it for a day: then see if it is still warranted or just a impulsive
act of anger related to "old baggage".
Respectfully,
Don

Hello Zmktwzrd,
Zac> Your referring to what's commonly called post-dictive errors.
dear fellow you can not explain something to a monkey. well maybe if
you have the time you could even teach a chicken. the only thing
that anyone will listen to is the sound of pennies rattling around in
the bottom of their empty account. admirable try thou!
Have a Great Day, Mark

Your referring to what's commonly called post-dictive errors. These are
something you need to be extremely careful about. They can slip into testing
very easily without noticing it, particularly on more advanced systems. Your
basically saying "if the market explodes to the upside by the end of today
then buy on this mornings open" etc etc.. Obviously this is impossible, but
you'd be surprised how often this error occurs in its many different
variations. Another one is "if indicator = x then buy on open." The problem
is that you did not know that indicator = x until AFTER then open.
