I think approaching trading by saying I want to make X dollars a day or a week is how people end up losing money. The market is not told how much money to give you and obliges. A system approach is based on seeing market opportunities and taking them, not saying I have to make this much each day or week. I have found that in all fairness the market does not give a shit how much you need to make today. What matters is do you have a method or system that can provide reliable entries for profits over the long-term and you take what the market gives you today.
