A personal system/strategy is a special design that fits your trading personality. This kind of system has to go through a vigorous testing and refining processes. They include backtesting, walk-forward analysis, optimization, Monte Carlo testing and more. Do you happen to know a coach who would provide this kind of service?
If you are trying to find or build a system/strategy that fits your trading personality (like the gurus say...), you have 99% of chances to lose money, consistently. If your are trying to find or build a system/strategy that makes money, you begin to put the odd in your favor. It is called being results oriented instead of process oriented. Good trades!
