Here are a few things I do in light trading weeks. First, I lower my expectations a bit; I feel that there will not be as many trading opportunities during a holiday week. Something that a lot of traders talk about is forcing trades. That means, even though a setup is not good, sometimes a trader will get into something that he knows he should not, just because he cannot find anything else. Second, I expect there will be more unexpected moves than normal. A good example is when a stock just drops quickly for no reason on very light volume and then rebounds. When I see this happen, especially to a stock I am in, I try not to overreact and just hit the buy (or sell) button. Certainly, there are some situations where you just have to get out, such as big size coming in to sell. Yet a quick snap in one direction can also result in a rubber band type move in the other. Consider checking your daily chart for near-term support.
