TD, I was referring to your comment:
<<Therefore, when you see a trade at say 16:05 it really is a trade at 15:50. I
think this is the case, I could be wrong.>>
If you are looking at the tape, what you see shows up 15 min late, but it has the time stamped on it down to the second.
If you are looking at the box after hours, and something changes, then its a 15 min delayed number, because the after hours trading do not show up as real time. However, if the change is before the close, then you have to look at the tape. If it matches, its a 15 min delay transaction. If it doesn't, then its real time.
Thus, this morning right after the open, the box showed the ask go to 13 3/4 and then 13 7/8. Since neither was shown on the tape, the changes represented real time changes that happened within the first 5 min of trading. |
