I have only been subscribed to this system for a couple of weeks, but from my initial experience this system works exactly as advertised. The entry orders are limits, so my entry prices have matched those reported by C2. I have not experienced much slippage on the exits, since the stocks are usually very liquid. I also like that fact that the vendor has a site that reports more of the system details and backtest statistics. It appears he also waited to accept subscribers until after a year of forward testing, which indicates to me he is not just trying to make a quick buck.
