$SPX vs. ES in Oddball

["jack zaner" <jzaner@xxxxxxxxxxxx>]

I have noticed, through the months that I have traded a variation of OB,
that results when using  cash prices ($SPX) vs. e-minis are consistently
better with cash.  The profitable cash trades are about 30% larger than the
identical signals for e-minis; the losers are about 40% less for cash than
the e-minis (exclusive of commissions).  Obviously the choice of trading
vehicle can be the difference between a winning outcome vs. a losing
experience, even though the trades are triggered identically.  The more one
trades, the bigger the difference of  final cumulative outcomes.  Cash S&P's
and e-minis may look alike, but they are different animals.   Unless you are
careful, you can turn a winning system into a  loser.  Try comparing them
for yourself.
Regards,  Jack.
