Hi all, So I've been looking into options for the past 9 months or so, reading up on volatility and practicing in toy (single contract) sizes. It's all very fascinating, and Dr Cottle's "Hidden Reality" book has got to be most interesting read I've done in a while. But I can't get rid of this nagging doubt. Take iron condors, for example, and any of the good books about them. They make it sound almost too easy. Like Benklifa's book says, just trade the math. Sell delta 10-12 two months out, buy further strikes, wait, exit, repeat. What's nagging me is if there is a statistical edge in that sort of setup, why aren't the big players doing the same in bulk and shrink the credit you receive until it's a tossup? And if the edge is not directly in expected payoff, where is it?
