I've been a net seller of premium over the last decade and done just fine. Edge comes from experience, quantifying over/undervalue of iv, using price based entries and exits, outright long back month options etc. The criticisms of high risk/low reward are accurate, but in the end it is largely psychology which is the achilles heel. Many should not use the trade structure and there are times when only long dn should be on. Working with the considerable premium available with flys is nice but some cannot successfully go the adjustment route. I'm way late to this thread party lol. I suggest taking a month and reading optioncoach's thread for anyone going down this road.
Have a great day.
