Since several users questioned the Z systems performances here I wanted to mention that Z12 just doubled my account after less than 4 weeks. Unfortunately I cannot copy & paste the full logs here since I had to restart the system several times due to initial problems with my new VPS and the duplicate ID issue described here. I'm running Z12 on an IG account via MT4 (Mini-Lots, leverage 200:1 for major FX pairs and indexes) with Margin = 500 and Risk = 5. I know this is high-risk (so don't take this as a recommendation!!) and I had floating drawdowns of -40% of my initial equity (fortunately after the first +50% gain) which were only acceptable knowing they were in line with the backtest results.
This is not supposed to be a commercial for IG (the unavailability of Micro-Lots and the stop distance limits are really annoying) but a commercial for Zorro and the Z systems!
