You have graph from last 3 months in the site and you claim that "We've been correct about 60% of the time." Getting it 10% better than coin toss in upwards trending market is not that hard.
Yeah the 60%+ is over the last 2+yrs. 60% is really not as easy as you'd think as it gives you a 20% edge 60% right - 40% wrong. Also my model's learning everyday and over the last few weeks has been doing pretty well as you can see. I'm working on an account system right now and will soon update the site with some more disclosure about my predictions and historical accuracy.
