Without following those rules there is no way to be a successful one except a succesful by chance. I learned from my past reading that is what i follow. There are lots of rules of them greedy plays a vital role. We can be greedy but always be logical. If you becme greedy while trading then you can be assured that there is 90% possibility to be a lessor. Make us do the reckless thing and need to be discipline about that. Not only in trading but also in everything.
