When you have a great trading system, it is certainly easier to meet your system objectives through your position sizing method however, you still have a chance to meet your objectives and profit with an average system if you understand how to position size properly. Others work so hard to get themselves a good system, but fail to realize that position sizing strategies are the key to getting what they really want.
However, they failed to understand that the key aspect was “how much” to invest in any position. Investment professionals have called this factor “asset allocation” or “money management.” Instead, it has everything to do with the “how much” factor when you invest or trade. Your success as a trader has little to do with selecting the right investment or even having a great system.
