I used to be a premium seller,sell an at the money straddle ,keep it at the money,and 17 out of 20 days a month,it'll erode, those 3 trend days a month,it 'll blow up ,so the odds of making money were a no brainer, you had to figure out how to protect yourself on those 3 unannounced days each month,plan a,you made enough to cover it,plan b,you made more on those days,his scalping technique sends him home flat each nite,no risk,as long as he's not too close to expiration,the beauty is he never picks a direction,he lets the market pick it for him,if he decides to take a day off or a nap, he's always neutral..he went from paying market maker commissions and haircut to retail and he has adjusted accordingly
