How does Blue Ocean ATS handle trades around the ex-dividend date?
Purchases made during the Blue Ocean Session (8PM–4AM ET) follow the same record date rules as pre-market and regular trading sessions.
If you purchase a stock during the Blue Ocean Session (8PM–4AM ET):
-
The Record Date is the same as if the stock were purchased in the pre-market (4AM–9:30AM ET) or regular session.
-
The trade’s session date (tag 75) is the date on which the Blue Ocean Session closes (post-midnight).
-
Example: The 20250211 trading session opened at 8PM ET on 20250210 and closed at 4AM ET on 20250211. Settlement occurs on 20250212.
Note: The TRF trade date is based strictly on the actual trade timestamp in ET. Tag 75 conveys the session date instead.
