It's good a risk management but make sure that you have your analysis in trading, like if your every trade is valid and that 10% profit is possible? It's hard to say that in your every trade, there's sure 10% profits, before you can do that, you should have supporting technical analysis/fundamental analysis. And also, there are also problem in stop loss, some stop losses are not triggered especially when the market does the flash dump and boom, sometimes you get liquidated by this.
