I've read this book a couple times. I like it, but it's important to understand this is not a book about a stock trader. It's a book about a problem gambler who happens to gamble on the stock market. One of the biggest trade in the book is just a hunch the character has, and they make bank because of an earthquake. Having an act of God rescue your position is not a strategy.

There's a part where he sets up a trust so that his family will money the next time he goes bust (which happens constantly in the book), and tells his wife that he will beg and plead for the money but she has to refuse him. That feels to me like the behavior of an addict capitalizing on a moment of lucidity to protect loved ones from their addiction.

The real Jesse Livermore died penniless by suicide. The book doesn't address his depression, but I think you do see it in what's not in the book. They don't really talk about the character's friends. They don't seem preoccupied with their wife or their children.
