The system is proven through 90% backtest and recent forward test. This is code developed from scratch and a unique system. The reason money back guarantee is not offered is as people have been abusing that policy. I have put a lot of time and effort into this system and thought by selling it everyone wins you get a good system and I would get to build more capital for live trading. I am a bit feed up with the skepticism on these boards and will probably take up an offer I've had from a private investor and stop offering for sale seeing as everyone is so negative about it.
