The parent comment is the most useful one in the thread so far for anyone who seriously wants to learn about quantitative trading.

Sports betting is essentially the same thing as proprietary trading in financial markets. The paper gives a good summary of a technique that was very successful in its day.

There is very little publicly available material on quantitative techniques that are useful for proprietary trading. Lo and Mackinlay's "non-random walk down wall st" was good, but that's 20 years old.

The mathematical literature on gambling is a lot more accessible. It's also probably easier to consistently make at least small money gambling, because the barriers to entry are lower.
