I think most technical indicators are lagging in nature, if you're staring at the es/nq all day you should be able to anticipate most short term indicators several bars beforehand (if the es has been steadily falling, suddenly spikes down, bounces, then floats slowly to its previous lows, you just know that MACD histogram is going to signal a "buy" divergence, etc).
IMO, the best clues in the eminies (especially the NQ with only 100 tech components) are the stocks and sectors themselves -- use the SOX, BTK, BKX, find the leaders and laggers for the day and keep an eye on how they trade. It might seem counterintuitive to watch the components of the indices for which way the futures may trade, but sometimes you can clear out alot of noise if you can catch the "play" for the day. JMO, whatever works -- this does for me.
