If you mean a money management when investing in forex, a good way forward is to never invest more than the 2-3% of your capital in a trade and of course don't open many such trades simultaneously.
Every experienced forex trader has his/her own approach when it comes to money management, but generally the don't put all your eggs in one basket concept, serves them all.
Manage money and make up for the lost deal ..
You should do a search for the "Kelly" method, or "Kelly Criterion". Nothing better is known. The big investment houses use it, in one form or another.

It's has an interesting history. It was originally a formula devised by one of the genius Bell labs engineers to determine the most efficient way to transmit electricity.

Best of luck and much success.
Peace.

Kelly Criterion is interesting if you have positive expectancy. The formula on Wikipedia says odds of winning x2 -1 with the odds being between 0 and 1.
So if you have a 51% chance: 0.51x2-1 = 0.02 or 2% of account
