I'm curious whether you guys have any insights into the making of a potential intra-day rally. What are some technical catalysts that trigger them other than news (i.e. bailout packages, interest rates, etc.) Although I'm not a big fan of oscillators or indicators, what are good parameters for a day trader to predict a potential rally. From my observation, the majority of rallies historically happen after 3pm, though there have been many cases where they start as early as 1:30pm. Another clue that I have noticed is that there is usually one abnormal pop of the futures. I like to watch the S&P 500 cash index (.SPX) and if theres a instantaneous 3 point rally during a 12 point range trading day, its very bullish. If this occurs in a down trend, however, there must be a tight stop because failed rallies lead to steep falls.
