By the way, I read your reply to the post by Brittlowry whereby he had NO premarket data for the IWM, so I followed your instructions to change to the Default 24/7 settings (it was set to Instrument Setting), and that made NO difference, it still showed PREMARKET data on a five minute chart, this was for the QQQQ.
NEVER MIND: I went to "US equities RTH" settings and the QQQQ chart now how the regular hours on it.
