The best management you can have is to project how much profit you want to make in percentage per week, month or year, divide by operation and put only what is necessary at risk, I can tell you what is the best money management, but only you will know your need, and what your trade model is, for example I try to risk more percentage to make more profit, always looking to do 1:3, I have already had many losses and many profits, the important thing is to always come out positive.
