Hmm, that doesn't seem like a good plan. You basically end up pricing in a 1% loss when you are ready to sell, right? You only sell after the 1% drop, so you only sell on the dip. Shouldn't you set a "sell order" at 1% above the current price and capture the fluctuation up?
Granted this is a bit of a game, but I try not to sell at times when the stock has poor momentum and I would probably be better off with a market order. I've been able to notch my stop loss price up a couple of times, to above the market price on the first day, before it sells. This technique actually has a name, it's called a trailing stop loss. You can set them to readjust automatically, but I do it manually in the evening when the markets are closed.
