"Nasdaq Weighs an Earlier Wake Up"
[Nasdaq OMX] said it plans soon to start processing trades at 4 a.m. The earlier start time is a challenge to rival NYSE Euronext, whose electronic Arca exchange began matching bids and offers for shares at that wee hour in 2005.
Nasdaq plans to make the change no earlier than March 18, it said in a notice to customers. The change is subject to Securities and Exchange Commission approval.
think about algos filling orders round the clock some day, maybe in 10 or 15 years from now, they would be spreading large orders over 24 hours. how insanely boring and quite would that make things.
