After monitoring a live trade I concluded that this style of trading system takes on more risk than I'm willing to accept. A stop was placed 12 points from entry while a limit order was in place for a 3 point target. When price went against the trade, the position size was doubled. Price eventually returned to a point close to break even and the trade was exited. On the plus side, the system developer will answer any question you may have and supply some back-test results. Since there seems to be discretionary elements to the system, the back tested results are a very rough fit to the live results. In conclusion, there are not enough trades yet to meaningfully evaluate this system. Specifically, it will be interesting to see the types and severity of draw-downs that are experienced.
