I don't buy straight long options with less than 60 days to expiry. I exit my straight long option 30 days prior to expiry because of the negative theta. If I've got a vertical debit spread then that gets closed also 30 days prior to expiry or earlier for the same reason. If I have a vertical credit spread (theta positive) I use a loss stop when I get to 100% loss (i.e. if credit is $300 then I'll close if I hit $300 loss or support/resistance broken, whichever happens first).
