Sir, you don’t have this ROI, this is a fantasy.
Let me explain you why.
You are trading a demo account. So your ROI is something not real, as you can have an account with any desired balance, and can open unlimited multiple trades without reaching a margin call (zulu followers have real limited accounts).
You have +590 pips in closed trades, and -1124 pips in losing positions. So you are in negative, so you matematically can’t have a 1600% ROI.
Maybe could be a good idea to start talking about your ROI once you have a really stable ROI, maybe after some months, and better after 1 year.
Finally, if you really have trust in your system make a little effort and trade with real money. I would put my money, and my trust in a real money trader.
