Market Making

The all-electronic NYSE National relies on a system of competing Market Makers to provide a fast, efficient, and consistent marketplace for all participants, including liquidity providers. Market Makers are required to maintain adequate minimum capital and continuous, two-sided identified and displayed quotes for all registered securities during Core Trading Hours (9:30 a.m. to 4:00 p.m. ET). They also clear and settle transactions through a registered clearing agency.

Market Maker Capital Requirements

Market Makers subject to the Aggregate Indebtedness Requirement maintain minimum net capital that is the greater of:

  • $100,000
  • $2,500 for each security that it is registered as a Market Maker (unless a security in which it makes a market has a market value of $5 or less, in which event the amount of net capital shall be not less than $1,000 for each such security) based on the average number of securities that such Market Maker is registered during the 30 days immediately preceding the computation date
  • 6 2/3 percent of aggregate indebtedness
  • The amount prescribed by SEC Rule 15c3-1

Market Makers subject to the Alternative Net Capital Requirement must maintain minimum net capital that is greater than:

  1. $250,000 or
  2. 2 percent of aggregate indebtedness
  3. the amount prescribed by SEC Rule 15c3-1

Become a NYSE National Market Maker

Eligible traders can apply in writing to register as Market Maker Authorized Traders (MMAT). Market Makers must meet rigorous education, training, and testing requirements to obtain NYSE National Equity Trading Permits (ETP), register in a given security, and remain in good standing with NYSE National thereafter to perform market-making activities.

Once a trade has been executed, trade details are transmitted to the Depository Trust and Clearing Corporation (DTCC®) / National Securities Clearing Corporation (NSCC®) for clearance and settlement via their Universal Trade Capture (UTC) processing stream. All trading transactions are transmitted to DTCC / NSCC electronically in real time matching the details of the trades from both the buyer and the seller into one deal record. These transactions are considered "locked in" executions.

Clearing firms must become NYSE National Equity Trading Permit (ETP) holders to obtain direct access to NYSE National and clear trades on behalf of exchange participants and be setup to participate on the NYSE National RIO. Firms that are not self-clearing must have their NYSE National clearing firm provide a Clearing Letter of Consent to the CRS / Membership acknowledging and accepting the financial responsibility for all of their correspondent’s transactions. To direct orders to NYSE National, clearing firms must complete additional membership agreements.
