The name of this man wasn't familiar to me, so I had to use the search engine as well.
I think he was the real "Wolf of Wall Street."
Jesse Lauriston Livermore was an American stock trader. He is considered a pioneer of day trading and was the basis for the main character of Reminiscences of a Stock Operator, a best-selling book by Edwin Lefèvre. At one time, he was one of the richest people in the world; however, at the time of his suicide, he had liabilities greater than his assets.
