Any hints on how he did it? I thought betonmarkets and retail exotics dealers marked up their products heavily.
Yeah, the edge loss was large, but essentially recovered in 24h on short gamma bets. He parlayed something like 30 bets straight. I know he went from 10k to nearly 800k the first year. Betting-limits were the limiting factor. He opened accounts in his friends names, but always funded those accounts and shared the proceeds. IOW, he would've made more if not for spreading the wealth.
BOM's bets are generally very close to bank indications and volbroker in FX. Maybe 120bp edge loss on index exotics (DNT at 54 with FV at 48). FX is much tighter.
