DRK order volume in time priority. 6.2 Phase 2: Re-Pricing of DRK Pegged Orders After the Phase 1 board lot allocation, a new Protected NBBO may be realized which will result in a reassignment of the executable price for all eligible DRK Peg orders. When this occurs the systemwill attempt to allocate eligible re-priced DRK Peg orders according to the steps noted in Phase 1: Board lot allocation. (Eligibility of a repriced DRK Peg order to participate in this Phase of board lot allocation is determined based on whether its pegged value is less aggressive than its limit price.). 6.3 Mixed Lot Allocation Mixed lot DRK orders may be entered as long as they are marked IOC. In these cases, the entire order will follow the same pricing rules as an equivalent board lot DRK order (e.g. if the order is a DRK Peg order, the odd lot portion will also be subject to the peg price). The board lot portion of the order will follow the same allocation steps described in Section 5.1 above. The odd lot portion of the order can trade independently of the board lot portion against a resting odd lot order (if matching on volume) or be automatically executed by a Registered Trader/Market Maker or Odd Lot Dealer (if priced at the opposite side Protected NBBO). 6.4 DRK Orders and the Closing Auction DRK Limit orders sitting in the book are eligible to be brought into, and trade, in the closing auction at 4 p.m. (or 4:10 p.m. in the event of a price movement extension). Any DRK Limit orders priced more aggressively than the same side TBBO, will be repriced to the same side TBBO immediately prior to the closing auction. DRK Limit orders will be matched second last in priority at a given price level; after any Market on Close (MOC), Limit on Close (LOC), or lit orders, but before any Closing Offset (CO) orders. 6.4.1 DRK order Tag Combinations The following order attribute values are not be permitted on DRK orders:.
