After 1 year demo with different strategies and trying out things what you’d never do on live as beginner, or testing the behavior of different pairs, and some Brent and GER30, I opened a live ac so the simple truth is in 14 weeks until now my loss is 11.8% and the lowest point was 15.3% 4 weeks ago. 8-15 trades per week, mostly daytrade, few swing.
Reflecting to the original question I think the answer should be counted relative to capital intended for one account. It’s no matter, how much is it nominal USD EUR etc. Everyone has different possibilities, environment (e,g in my country the avg monthly salary of workers is $ 900-1200) but there are also people who have much more. The only thing what counts: N amount you invest and the X% profit/loss you are able to realize constantly let’s say on a quartely basis, (or else depending trading time and frequency). All that with completely balanced with the personal lifestyle. Must set own goals and measure the result always to that, in my opinion.
