Quote from neke:
You are displaying you own ignorance as well. I understand as much, if not more, than you about risk management. A stop loss is percentage does not mean risk is absolutely limited to that! Not putting a stop loss does not mean you are going to lose the whole amount, dude. Think in terms of probability, and you will be better for it.
Let me give you a little quiz. Suppose your trade has two possible outcomes: a gain of +20% or a loss of -10% with equal chance. Would you trade this scenario? What percentage of your account will you commit to each trade? Give me you answer, and I will see how much of risk/reward analysis you understand
