I've been using the demo for six months now. Tried all versions and modes. The results obtained during this time convinced me of the expediency of purchasing this Expert Advisor. There were no drawdowns, and this surprised me in a good way. I was also struck by the ability of the bot to identify and bypass flat areas. Given today's action, I think that 700 bucks is a good and profitable investment. I am ready to become an OPTI license holder.
