Mostly right is a mostly correct statement. Heard of Renaissance Technologies?
IMO, continuous time finance is a flawed model. Academics always rattle off theorems based on assumptions that do not hold across all time scales. I've worked with traders lacking any formal education that have a better understanding of the market than someone like Protter will ever have. Trading isn't about investing; it is about capital flows.

That said, I don't miss the job (only the $).
