With my new strategy, a "big" day is defined as 0.4% gain or loss. (What can I say, this produced the best results).
Per this strategy, He is todays possibilities for my port: if the NDX closes > 6 points, I will stay in cash. Should the market post a small gain or loss, the position will be 25% long. A loss of > 6 points and I will go long 50%.
