Fari Hamzei is a great guy, I used to subscribe to his site, it had a lot of good info for analyzing volatility and trading derivatives in general. He is trying to get 2,000 twitter subscribers by the end of today. He currently has 1,939, so It won't take much to reach the goal. It's of no cost to you, just plug in your email address to sign up for twitter. Here's Fari's link: http://twitter.com/HamzeiAnalytics He posts his program trading detection, and index futures trade on twitter. So, it's a good way for a beginner, or someone who needs a little guidance to follow along real-time for free.
