I recently bought trendpro software from Roy Kelly and found that it is not accurate at all. Even after I did some 'twicking' or adjustments, it was giving so many losing signals that I had to ask Roy Kelly for a refund within a week. This he declined. It was really unfortunate that the claims on the website that they stand by their words is totally untrue. They claim to have documented evidence that the software is good but my actual experience contradicts their claim. The lesson for all traders is this - NEVER BUY A SOFTWARE THAT HAS NO REFUND POLICY OR THAT DOES NOT STATE CATEGORICALLY ITS REFUND POLICY.
