Until you stop dealing in dollar figures, you're not going to find any answer worth a damn. The sign of inexperience in a trader/investor, dealing in absolute dollar figures. You need to switch your thinking over to percentages, risk/reward profiles, entry/exits, and overall realized movement v. anticipated movement. Until you can work daily and consistently without having to look at your P/L, you will not really get anywhere. Good Luck! P.S. Putting daily goals on your account (like I'll stop when I'm up $X) is only going to handicap yourself in the end.
keeping these "stops" for the day has been key for me before I started doing this trading was much harder
