I've been there, and I've done the exact same thing -- given profits back on retracements (and even taken a loss). Like I said, it's up to you as to when you feel it is right to trade.
Congrats on your profit cmajr..... As to previous investment decisions, that could simply be stated that you've been with the wrong group. I know people who sold CDIV at .07 and under because of previous bad luck. And now where are we?!
