Much to long to even get into here, the summary of it is this. Events cannot
really be priced into (except perhaps earnings reports) the index markets. Instead traders keep score primarily with Fib fan/levels, price pointers, and a few gimicks I have my own names for. Of course who knows, I didn't write the algos, but this is my understanding after a lot of years of day trading.
See for yourself, it takes some careful reading/studying of the examples, but you will then agree there is value to what I say. There are some other both related and unrelated articles you might find interesting.
