I will agree with the rules of the author, but want to add that if you want to earn on it. You should invest a lot of your time and money. Only after these losses, you will have an oppurtunity to make profit!
Right.There's no magic in trading and everything will be learned in a long period of time.You should have to endure even lot of hardships and sleepless nights,and of course enough amount of money so that in return you can also gain good amount of profits.
