As long as one sold at planned price and made money, it's all good.
After so many times in so many years I left money on the table, I don't have any feelings any more, I just move on to the next opportunity.
Most recent example: after I closed my EUR/USD position for a tinny +29pips(hope my memory is good enough), it moved up at least 150 pips in one day!
There are always more opportunities in the market, be happy with your profit.
