Summary of the Changes
Incoming odd lots will match with any odd lot orders in the book. For securities with a Market Maker, the incoming order will trade with any booked odd lot orders at a price better or equal to the existing bid/ask. Any balance will then be filled automatically by the Market Maker. For securities without a Market Maker, incoming odd lot orders will match with any orders in the book, based on the price/time priority.
