I think Thorp's story is much more common that most here want to admit.
There's a LOT of confirmation bias (as well as other behavioral biases) when it comes to chart-reading. I used to look at charts and think I'd found some amazingly profitable pattern. Then I'd test the idea over a longer time frame with a statistically-significant number of occurrences. It would almost always lose money or be breakeven-ish.
Also, of all of the self-proclaimed successful "pure price action traders," I've never seen one with a profitable, verified long-term track record.
