It depends on your trading method. If you're a scalper or very short term trader, then you likely could have a daily goal. My egy is similar to a casino. Playing my formulation when I have an edge but only because I have an edge does not mean I will observe that edge go my way every day.

I do have a goal that is monthly. 400 pips a month plus I evaluate my formulation based on if I am hitting this. I don't evaluate based on day one of a month daily 30 of a month. I assess it based on a rolling 20 trading day pip yield.
