As a followup,
Be careful about those who claim that "statistics" show that trading strategies, since they were successful in the past, will be successful in the future.
It would be wonderful if we could trade last March's corn, or the S&P futures contract from 1993, but those contracts have expired. Backtesting those reveals something. If only we could do some "futuretesting."
No one knows the future. Bottom line. Statistics only tell us the past, but that's all. Backtesting may have some utility, but it should not be a crutch. Backtesting over a short period should be a red flag.
We can, however, control our exposure to the markets. Unhedged premium sellers will ultimately be wiped out, given enough time, exactly the same way that, if given enough time, a orangutan typing on a Word Processor will somehow write John Milton's PARADISE LOST.
Good luck to all.
