Trying to Understand Option Strategy Straddle

[moka2]

Straddles can be used successful on stocks before earnings. You buy them around 7-10 days before earnings and sell on the day on the announcement. Most of the time you can gain 10-15% either from IV increase or stock movement.

I was more interested in weekly Option on Index futures ( not single stock options)
and how to back test if purchasing a straddle "X" days before expiry is effective!

Don't bother with weekly options-they are priced to eat you alive
