I don't see any logic here, you mean to say, buy the dip and when it further drops, you sell it? Why would you even bother to enter into investing if your goal is to loose more money than gain it, I think younneed to rethink your strategy, the first one is ok, buying the dip, but sell it if it drops 10 to 15% more once you already have the investment, i think that is just insanity, why not just give away your money to the rest of us,and we can assure you, we can double or triple it for you.
