I have been a member since 2005. I did a lot of back testing through 2007. However, in 2009, when I re-ran a long term (7-years) test I had done earlier. The results were different.
I extracted the trades from both the runs of the strategy and found that several of the companies that did not survive the financial crisis were effective removed from their historical database. I called support and they confirmed this. I also discovered that when stock symbols change names it causes and issue in their database (I think you lose the historical data of the old symbol)

However, with all of that, I must say they have come up with a new timing system called the "Sure Fire Success (SFS)". SFS is a long only system. They have a similar on that is long and short but you have to manually test this unless you have

This occurred between Nov 21, 2006 and Dec 26, 2008. That being said there was about a 273% gain (an
I think on a go-forward basis, VV is really good. I just have issues with the back testing. Their support staff is really good and many of them actually are trading using the system.
I am attaching the report that was generated using the mentioned back test of the SFS detailed above.
