You always have to think that every moment in trading is going to be different. You can never ensure that an operation will work out well, but if you can bet on behavior that most of the Sometimes it repeats. With this way of thinking and acting you will win. Simply act when the odds are more in your favor. The times you lose, other than having acted badly, you should simply lose when the least likely happens. If from 10 operations you are victorious in 6 or more, you will be working correctly. When you lose 2 or 3 consecutive times, your mind will start telling you to change your system, that something is wrong. Those are the moments when you must stand firm, since you know that your system works and you are respecting it. The worst thing you can do is start to vary and skip the rules. Trust you, your system, and you will achieve it.
