Sorry Eliot
It was a University study done on about 250 trades. It showed the account profit for long straddles, nearly doubling if you applied this modest simple money management rule, of dropping long straddles that had lost 10%. It didn´t go into a lot of detail, but I ran across it on the internet.
Regarding the late week trade recommended by Forex Forex, it was only 2 contracts and made $38, but I notice my CASH ACCOUNT balance only went up $14. Bit expensive what? Almost 2/3 went to expenses.
I just made up a record scrap paper to compare Implied Volatility averaged for a Long Straddle, and the Long Straddle Spread cost and see what correlation if any might be there, for the best time to enter a Long Straddle. Trend turns, middle trend, or what? Anybody done any such studies, or know of any? I´m talking very short trends here of one day, or two days during the week. Usually a WEEKLY bar will move a fair distance, perhaps two strikes sometime during the week, which should be enough to make a Long Straddle profitable. Thats my theory anyway.
