4% is just a rough estimate based on my previous comment noting my stop losses: 0.9250 AUD/USD and 1.4850 EUR/AUD, it's probably much less than 4%.
As far as money management goes, a 4% loss on any account is pretty small. Especially if you compare this to most retail traders who usually draw down their entire account. Maybe at 10-20%, you would be pushing into "aggressive money management" territory but anything below 5% is pretty solid for a loss.
At this point, I should remind you that the current account I have tracked on myfxbook was set up recently to track performance of my analysis only. It's by no means a 'fully loaded' account so there's no money management used here. For the purposes of comparison, 4% of my tracking account represents less than 0.1% of my overall portfolio size.
Having said that, I'm considering funding a new account with something more substantial (but still newbie friendly) to trade for real. People have been requesting I connect a live account to myfxbook so they can see how I load positions with proper risk management. I'm not sure how I want to do it or whether or not I even want to do it yet but it's something I'm considering. I'll make my decision by the end of Q1 (Mar 31st).
