Ashley, not sure about what you're asking with the gap question, but I do think gaps get filled in the general direction of the market. Maybe someone else on this board can help you better. You might also want to ask the following IHUB board: http://www.investorshub.com/boards/board.asp?board_id=1320
As for the time question, I think that the market is too unpredictable, because news or rumors could move it. It's also a guessing game whether the first 15 to 30 early morning run up is serious about staying, if there is one, so most scalp first and ask later. I wish I were better at that, but I'm learning from my mistakes. Check out a 10-day chart on one of the Q stocks or the Nasdaq and you'll see what I mean. I noticed that, on the last 10 days, on the Nasdaq that once a direction is chosen in the morning it usually continues in that direction throughout the remainder of the day. That doesn't happen every time, but I'm going to start watching it to see how often the momentum changes major direction each day. It's just an observation, so I wouldn't be surprised if I was completely wrong and some seasoned chart readers refute that.
I really think that it is too hard to pinpoint times, because every day can be moved by different variables. Just look at the charts, but 10, 11:30, 1:00, 1:30, 2:00, 3:00, and 3:30 might be watched for movement. You might also watch the Datek streamer, or the like,(if you have one) from 9:00 to 10:00 to see where the fear is the strongest (i.e. who blinks first).
