Fractional End of Day Summary Message Fields
The Fractional End of Day Summary message is used to give a consolidated, high-level overview of a security for the day, based on an end of day summary message received from either the US CTA or UTP Securities Information Processor (SIP) feeds. The message will be sent after it is received from the source and the delay period has expired, currently 15 minutes. The system may send more than one End of Day Summary message after the end of a trading session due to multiple CTA/UTP end of day summary spins.
