I would disagree in the case of SPY.  If you're a long-term trader,
SPY is a good approximation for the S&P.  If you're a short term trader,
I would warn you against using a system based on SP data to trade SPY.

If you compare daily bars, they don't match closely enough.
Recently I tried out a variant of Oddball using SPY instead of the
actual index.  Try as I might, I could not make it profitable.  Same
identical trades in both markets, but using SPX made money quite
well, while SPY lost money like crazy.
