Retail Price Improvement (RPI) Message Fields
The Retail Price Improvement (RPI) message is a retail liquidity indicator that includes symbol and side, but not price and size. An RPI message will be disseminated when there is a retail price improving order present for a symbol on any Cboe Exchange order book OR to indicate a RPI order is no longer available. RPI orders offer price improvement in increments of $.001 to Retail Member Organizations.
