Hi hilal, Demo trading compared to Live trading is like comparing learning to drive on a simulator to driving a real car.
There is some value to it, but Live trading is very different & much harder. At some stage in your trading journey you will need to leave the safety of Demo trading & do it for real.
If you are agonising over it - don't do it. If not - start live and start very small.
You don't mention if you have funded your Live acct yet - if not that is the first step.
Your profit will always vary month to month - 4 weeks is not a long time to make assumptions on whether your return is sustainable or not.
