“Your order is configured to work during regular trading hour only. Our smart routing system does not consider a market to be open until the primary exchange posts their opening indication. When Nasdaq reports their executions to the consolidated tape prior to 09:30 est, each report is flagged as “pre market”. At 09:30:00 any Nasdaq trades that occur are reported to the consolidated tape without the pre market indicator. This causes 3rd party quote reporting (Bloomberg, ILX, Reuters, etc) to see the first of these prints as “opening” prints when, in reality, they are not. “

Overall has been in my favor over that small sample but it has been a bit of a scatter above and below…
