I don’t really have any ratios - that’s not my thing.
That’s like asking me how many slices do I want in my pizza.
Sometimes I’ll slice the pizza into 4 slices because I’m not hungry enough to eat 8.
My risk is usually 10%, in this case £1000 - the rewards depend, you have to look at it day by day, week by week. Things change and sometimes you have to take whats on the table and be happy.
