Liquidity Programs


Supplemental Liquidity Providers (SLPs) are electronic, high volume members incented to add liquidity on the NYSE. All of their trading is proprietary. All NYSE stocks are eligible, but not all have SLPs. Supplemental Liquidity Providers are primarily found in more liquid stocks with greater than 1 million shares of average daily volume.

  • SLPs must maintain a bid or offer at the National Best Bid or Offer (NBBO) in each assigned security at least 10 percent of the trading day
  • SLPs trade only for their proprietary accounts, not for public customers or on an agency basis
  • SLPs that post liquidity in an assigned security that executes against incoming orders are awarded a financial rebate by the NYSE
  • An SLP can be either a proprietary trading unit of a member organization ("SLP-Prop") or a registered market maker at the Exchange ("SLMM")

NYSE Arca Market Maker

The all-electronic NYSE Arca 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.

NYSE Arca appoints Lead Market Makers (LMMs) for ETPs (Exchange Traded Products) with a primary listing on the exchange to meet defined obligations in exchange for incentives such as lower transaction fee.

NYSE and NYSE Arca Retail Liquidity

The NYSE and NYSE Arca Retail Liquidity programs promote cost savings through price improvement for individual investors on retail order flow for securities that trade on the NYSE and NYSE Arca markets. Offering price improvement for retail orders within an exchange environment offers individual investors new economic incentives and provides greater transparency, liquidly and competition in the U.S. cash equities marketplace. The program can be utilized by retail firms directly as well as by the brokers that service retail order flow providers.

Two Classes of Market Participants

  • Retail Member Organizations (RMOs) who are eligible to submit certain retail order flow (Retail Orders) that is eligible for price improvement.
  • Retail Liquidity Providers (RLPs) who provide price improvement for Retail Orders in the form of non-displayed interest priced better than the best PBBO. RLPs received economic benefits in exchange for meeting performance obligations. RLPs that miss obligations do not receive enhanced economics. The Exchanges have the right to revoke RLP status.

All members, other than RLPs, are also permitted to submit Retail Price Improvement Orders (RPI) and interact with incoming retail orders.

Retail Order Overview

A Retail Order is an agency that originates from a natural person and is submitted to the Exchange by an RMO. The order cannot originate from a trading algorithm or any other computer methodology. The Retail Order interacts with RPIs and other available orders that are priced better than the contra-side PBBO. Both NYSE and NYSE Arca send an indicator to both the NYSE XDP and SIP feeds when RPIs are available, indicating the side of the interest but not the size.
