Thanks everyone for these answers. To answer you Lucrum, I traded my systems in real time with my money but my account is quite small (around 30000 $). I began trading my systems 2-3 months ago and I made around 700 trades.
My annual Sharpe is around 3 for the systems and capital I use at the moment. With more money and the same systems, It could go up to 4 or 5, as I could take more trading opportunities. Did not try however to improve the Sharpe further than that as I do not have the money to exploit it for the moment.
