I don't know anything about Carrie Wood. The firm where I work (same niche as Jane street) makes so much money they don't know what to do with it (spoiler: they distribute it as huge bonuses).
You're starting to sound like one of those "the market is efficient you can't make money trading" morons.
No I genuinely want to know about how they make money. Is it through better trading, "alpha" or through technicalities like order flow volume etc.
Of course you want to know how they make money. Everyone does.
