Missed opportunity?

I had to leave today and set a limit on a half position I have open that was within 25 pips of my target. When I returned I found that my limit was 4 pips over the highest level reached today. Was my target too high? I don't believe so. This is a business and my plan is to make a certain amount of money on each trade, so if the market doesn't want to give that to me today then I'll wait a while longer.
