The Retail Price Improvement (RPI) order is a liquidity-adding order that works within the parameters of the NYSE Retail Price Improvement program. This program allows qualified stock orders to fill against eligible, hidden RPI orders that offer price improvement over the current best bid and offer.
Customers submitting an RPI order must specify an offset (which is the minimum price improvement amount) of at least 0.001. The order's limit price is used as the price cap for the order which, when submitted, acts like a relative order and is pegged to the best bid (for a buy) and the best offer (for a sell) plus or minus the required offset. Once submitted, the RPI order is routed to a separate book at the NYSE where it is eligible to interact with qualified orders.
The Reference Table to the upper right provides a general summary of the order type characteristics. The checked features are applicable in some combination, but do not necessarily work in conjunction with all other checked features. For example, if Options and Stocks, US and Non-US, and Smart and Directed are all checked, it does not follow that all US and Non-US Smart and direct-routed stocks support the order type. It may be the case that only Smart-routed US Stocks, direct-routed Non-US stocks and Smart-routed US Options are supported.

The current NBBO for shares of stock XYZ is $10.10 – 10.11. You create a sell order for 500 shares and select RPI as the order type. You enter 0.001 as the offset, which is the minimum price improvement amount. You then enter 10.10 as the limit price which acts as a price cap for the order. For the sell order, this is the lowest price you are willing to accept.
The RPI order goes in at 10.109 (Best Offer – Offset, or 10.11 – 0.001). If a buy order comes in at 10.109, it will hit this offer and fill.
|Market Price (NBBO)||$10.10 – 10.11|
|Limit Price (Price Cap)||10.10|
|Offset (Minimum Price Improvement)||0.001|
