This could theoretically make up about 1120% p.a. Not bad! ;-) As I understand it you make this with stock and index trading only, ie. without any options trading, right? Is your system maybe something like a HFT?
It is a personal HFT with pattern recognition, neural networks (AI self-tuning), automatic "skimming" of trends, it is doing well. Have two offers, negotiating over the weekend, likely it will be sold to an individual or software company and I'll become a consultant to them. No options at the moment though it could.
