Oh I love to do detective work as well.... and good job!
Ok, so if this 10% figure actually adds up, and he didn't just steal this guy's story, then one has to really wonder why he is back at the bottom. I'm sure the strategies he used back then no longer work given HFTs, which I guess was essentially what he was doing if he had so many round trips, but you would still think that someone with such a deep understanding of the markets wouldn't need to be starting from scratch.
NOTHING works the same as it did pre HFT. The very structure of markets are completely different now.
Only the absolute ignorant, and those trying to sell the morons believe different.
