Reminder: Odd Lot Transactions User Acceptance Test

As a reminder, FINRA will begin disseminating odd lot transactions via the Trade Data Dissemination Service (TDDS) on Monday, December 9, 2013. To support odd lot trade dissemination, FINRA will introduce the new sale condition modifier, Odd Lot Trade ("I"), which will be available to any participant to distinguish a trade resulting from a market center's execution in increments less than the defined round lot size. Odd Lot Trade transactions will be included in volume statistical calculations only. The Odd Lot Trade modifier value "I" will appear in the Sale Condition field of TDDS transaction messages.
