when I first started trading ES, the first year I made less than I could have made at min wage, the only thing that saved me was the 60/40 split (even though with the exemption I probably wouldn't have owed any income taxes one way or the other).Well, I didn't have an exact price point set at which to exit...more like a price area. I would usually have to see how price acts when it reaches that area. I've only executed this once with success, other times, I get out prematurely for no reason at all other than to take the profit and be done with it.
I had a (back in those days) $50 electric bill and 1 point profit, and I would take it. "Well there! Just in two minutes I have paid the electric bill!"
