If this is the start of your adventure into FX speculation then I’d certainly have the mindset that this live account [and congrats for going live to start with, you’ll learn a lot from an emotional point of view] should be used to simply break-even at best. It might sound simple or easy, but even that can be a challenge in it’s own right, even the professionals have losing months from time to time.
I’d say that the ball part figure for typical monthly gains based on the verified accounts that I have seen over the past years is between the 5% to 10%. Some months may be less, even at a loss, whilst other months may be considerably more than the top end of 10%. Essentially, it will average out, but the swings from account gains month in and month out should also be rather consistent, this is a great measure to use when looking at longer term account stability. I believe myfxbook uses a standard deviation upon expectancy to show this exact point.
But, to start with every new traders / speculators aim should be to get to the point where they are averaging out at break-even whilst sticking to a trade plan the entire time. Chasing a loss and making back your losses by taking a non-tradeplan approach is the risk (we’ve all been there - it’s even more dangerous when you happen to pull it off as it fuels you to do it again and again. At some point you’ll over position size to cover the loss and blow your account).
