It's been working out great for me. I stopped losing money and now am starting to make it. Leeds is best for swing traders anyway, not for the true investors. My hold time is averaging a week to two months. Looking at the archives though tells me to be wary of their projected short and long term sell prices. I primarily use it to find companies that have reasonable AS/OS and don't have the CEO taking insane amounts of money like GZFX.
Once you've filtered out the scam and sham companies, that's half the battle right there. Now just hunker down and take your percentages and flip 'em.
