I've traded Synergy for a year - what do you want to know about it? You can call Dean directly - he is very responsive.
Apart from the fact that the code is locked (and why shouldn't it be, it took him 10 years to develop his system), you can't really trade it yourself unless you have a copy of TS2000 and a datafeed like CSI. (He is working on a standalone platform like Aberration.) The current online version of TS7 does not have about 7 of the 21 commodities traded by Synergy. I like a lot of the features of this mechanical trading system - risk weighting of different commodities, scaling, tight stops. Having said that, I am down from my original position - but so are virtually all trend following systems recently.
I recommend this system if you have a very long time horizon (10 years), the amount you put into it is ABSOLUTELY extra petty cash that you have lying around and don't know what to do with and could care less if you lose most, if not all of it. I'm serious, I believe if you go into these kind of systems with this kind of mental state, you have a CHANCE of making a good return over the long haul. Check out Dean's performance graph, they take a while to get going. - rcm.
