Definition of a Market Maker

A market maker is an IEX member firm that buys and sells securities at prices it displays on the IEX Order Book for its own account (principal trades) and for customer accounts (agency trades).

IEX offers a market making program where IEX members can register as a market maker in a particular security. Registered Market Makers will be obligated to enter and maintain two-sided quotes at prices that meet the designated percentage, as defined in Exchange Rule 11.151. Firms can register as a market maker by submitting the IEX Market Maker Application. See below for further details.

Registered Market Makers can qualify as an Enhanced Market Maker by registering as a market maker and meeting tighter quoting requirements with principal orders in each IEX-listed security. Registered Market Makers do not need to register for the IEMM Program – firms qualify for the program based on their quoting behavior in IEX-listed securities.

  • Quoting 20% of the day at the NBBO will qualify for the Inside Tier
  • Quoting 75% of the day at the greater of 1 MPV or 3 bps away from the NBBO (or more aggressive) will qualify for the Depth Tier

See IEX Enhanced Market Maker Program for additional details.

Market Maker Peg Order Type

To support Market Makers with their quoting obligations for registered securities, IEX offers a Market Maker Peg order type. This order type essentially functions as a displayed Peg order that will allow for quoting at an offset to a defined Reference Price identified by the Exchange. A Market Maker Peg order is repriced by the System when the Reference Price has moved a defined percentage away or towards the order. See the IEX Market Maker Specification for further details about the Market Maker Peg functionality.

Benefits for IEX Enhanced Market Makers

Market makers that qualify for the IEX Enhanced Market Making ("IEMM") Program at the end of a calendar month receive a discount on trading fees for all securities, not just those registered. By submitting an Application to Aggregate Activity of Affiliated Members, the discount received by the market maker can be extended to the affiliated Members’ trading activity.

Members that qualify can earn a 1 mil (i.e., $0.0001) discount for satisfying either tier (2 mils for satisfying both). The discount is applicable to the transaction fees of all securities traded on IEX priced at or above $1.00, excluding trades subject to the Crumbling Quote Remove Fee (i.e., 30 mils) or the Internalization Fee (i.e., free), as well as any executions resulting from an IEX Auction. See IEX Enhanced Market Maker Program for additional details.

Requirements for UTP Trading of Commodity-Based Securities

Market Makers that trade commodity-based securities must submit the following to IEX:

  1. a completed disclosure report, and
  2. written procedures addressing information barriers, books and records, and handling of material non-public information in order to make markets in these securities.
