Let me try again. It seems to me that a useful tool to trade at the opening would be a real time order imbalance on the NYSE? Does anyone have any idea on how I can find what listed stocks have order imbalances prior to the market opening? I have read from Don Bright how one may trade the opening but with out this imbalance order information I would find myself at a disadvantage. Does anyone use order inbalance or opening trade strategies when trading sectors?
