Ive had my copy for almost 18 months now, still open it every trading day, ive branched out into other things, however I still find good trades using it, i don't like their built in portfolio mgr too much, but apart from that the backtesting, charting, trading signals and overall layout is solid work and relatively simple to use. I haven't used matlab, so can't comment there. The only other comparable software I know are from the pairco bright guys, but it's twice the price and you have to clear through their REDI platform to use it, no thanks. Jared at PTF has done a good job of continually updating and supporting the software and for that he should be commended.
