BrokerTec Notes

The BTec Gateway supports WI (When Issued) and OTR (On-The-Run) bonds. For US Treasuries, when a new WI or OTR bond becomes available on the BTec Gateway and is subsequently traded, Trade Tracker will create a new InstrumentID in the tblInstruments table. The SeriesKey will be the same as the previous WI or OTR bond, but the Instrument and ExpirationDate fields will change. See the BrokerTec Gateway System Administration Manual for more information regarding the representation of BTec instruments.
