In a previous life, I worked for several proprietary trading firms in Chicago. During my time there, I learned a few things. I also made a lot of money. And I still use the same strategies today which I used then, albeit, with some modifications. Technology changes but the fundamentals always seem to stay the same. If you would like to get an inside look into what happens in the world of proprietary trading, I invite you to read through this site and watch some of the videos I have posted on youtube.
