I am trading this system since middle of December 2013, with a total profit of $9000 to date. Initially I used G3 AGM/IB but I stopped it because the G3 fees with AGM are just not fitting this relative trading intensive system. I switched to Trader68, had some issues as well but Trader68 provided a fix and since then it runs smoothly. Using a G3 Broker only makes sense if you have low fees e.g. 3-4 per contract max. John, the system developer is very responsive, answered every message promptly and provided additional information on his performance track record. I can recommend this system.
