This site (derekgu.com) will no longer just talk about Investing and Options topics. This site will become more of my personal blog site. For any subscribers who like to continue to receive financial blogs please join the optactic.com .
Finance is just part of my hobbies. In fact, my true passion is in game development, or more specifically game design, and art creation. By switching focus, I can blog more frequently. I have lots of topics to share with people, including game development, software engineering, algorithm trading, options trading, philosophy, politics or even movies I like. And I will blog all these.
