Why stop trading at 4pm and then have "AH" and "pre-market" trading? The Nasdaq should be set up for 24/7 trading, other markets (NYSE, AMEX) as well.
How do you figure? A major reason the 87 crash was so drastic was because the market was closed overnight, and therefore opened extremely lower with no chance to get out. Lower open triggered stops, rippled through to the futures markets, etc
Well futures are now open all night. If someone needs a liquidity source at 3 a.m. it's there. But no way is someone overseas going to be making a tight market in some POS Naz issue in the middle of the night.
That way I can't sleep at night and things can happen while I'm not monitoring my positions. no thanks
I assume taht everyone that posts to this site is a trader, so it boggles the mind that anyone in their riursght mind would want the market action dilted over another 16 hours. I say let's have 2 sessions: 8:30 ET until noon and then reopen at 2pm et for two more hours
