Also, excuse me if this statistical point’s obvious (others may not find it so!) but it’s worth knowing that that “roughly 5% average profit per month” usually conceals quite some variance.
The figures averaging out at “5% profit,” for the tiny minority who get there - which doesn’t yet include me! - might range from +25% to -5%. In other words, there are normally some losing months, too.
This is why you need to be so sure you have a real edge, and be confident of your statistics first, so you don’t get dismayed when that happens without you having done anything wrong!
