This has been going on for the past few months. Dow rallys, Nasdaq falls. Back and forth we go. Im betting tonight YM will rally, and tomorrow during the cash open. Last week the Nasdaq squirted up and then drifted in a tight range. Today Naz squirted up and YM Stayed down. Im long YM @ 34130, looking to sell @34220
when there is some very major event/news, then ES YM RTY NQ ( US index futures) will all move in tandem; ie they will be highly correlated. When there is no major event/news, there will be no correlation. The same behavior also happens to the Asian & European index futures.
