I have been using the Sharewealth SPA3 Mechanical trading system for 6 years and found it to have a very positive edge on the market with good results. The online education webinars and helpful public forum for members take a lot of beating.
I use the SPA3 system developed by Share Wealth Systems for 3 different portfolios one of which was started at the worst possible time in August 2007 just before the GFC. On that portfolio I am getting a return of 12.96 compound annual growth and the others are doing better as they were started at more favourable times. So I am smiling. I also don't think Simon and the Standard Bank would have bothered to have Gary Stone, the founder, come out here and give a serious of presentations around the country if it was a bad product.
