use 10% of your trading account to trade and then you do well in forex to get a good income like that if you put SL 10 pips then use 1 volume at $ 100 capital and like this if you have big capital, use it like that and increase your volume as your capital and I personally only use 5% risk per trade. I think that setting such a risk is very important, because it is part of an important discipline we continue to learn from my mistakes so mistakes happen too often, if the mistakes are too frequent even though we discipline will still run out of our accounts.
