As far as late prints are concerned, there is another explanation that wasn't mentioned.
Many times "phone" trades are the reason for late prints. When I traded with a contra via phone, sometimes I would wait over 90 seconds for the report.
Here's an example....
I (SBSH) make ABCD and I'm bid up at 10.01 for 1K, the ask is 10.05. I get a call from MSCO. They want to sell me 2,000 at .01. I say ok, "done" get the trader's name, write out the ticket and time stamp it. I go into NWII (Nasdaq Workstation 2) and report the buy. I use a system with NWII called ACT. The buy stays there, until MSCO reports and confirms the trade through ACT. The trade will never print to the tape until both sides confirm the trade.
The trades are supposed to be reported within 90-secs, anything more is a violation. The violation becomes apparent if one of the contras files a grievance with Nasdaq. I only had to report firms if they didn't ACT the trade after several hours. My firm was inthe clear because we reported the trade within 90-seconds. When you're looking for orderflow, the last thing you want to do is report a firm. You get a bad rep on the street. FYI, NITE was one of the biggest violators of this rule. They were fined several hundred thousand for reporting trades late on a regular basis. NITE was a VERY busy firm, and it could be they didn't have the time to ACT the trades.
Many times big block trades are reported late because they can throw technical indicators off balance and many neophyte traders mistake "sld" trades for extra-market price action. I only look at blocks that trade through highs and lows.
