I will use Demo as well but I will not Demo test my strategies before going live, I will still continue to demo test “backup strategies” if I need to switch out some of the ones. Testing this way on “Out-Data” work as well as demo testing. Markets change anyway so it’s not a guarantee that the strategy will work live if it did on demo.
I go with enough history data to feel confident + 80-90% Monte Carlo + the last step is the one month of “Out data” I don’t feel that I need more confirmations than that, this way really saves Weeks or even months so I’m willing to take the risks.
Hey, I’m compounding profits so lets start to compound time ;-)
