Mate, it is really up to you.
But the fact you asked is clearly showing you are not ready. So why don't you pay some more attention in demo until you are ready and confident enough to trade live.

When you say you are confident. What gives you that feeling. Have you made consistent profit on the demo account? Have you even consistently broken even? You've done 3 months forward testing on your stategy but how much back testing have you done? What were the results of that vs what you have experienced on demo?

It is ultimately down to you but I am a firm believer that if there is no evidence you can make money long term on demo then adding real funds into the mix won't suddenly change that.
