EUROPEAN BEST BID AND OFFER EBBO

The European equivalent of the National Best Bid and Offer (NBBO). The EBBO refers to the current best prices available for selling or buying a trading instrument such as a stock. On any exchange, a series of price levels appear for both the buy and sell sides. The EBBO represents the best price that is available - the lowest price for a buy or the highest price for a sell. The EBBO continually updates the prices so the market participant's have fair access to the best prices.

The EBBO guarantees that market participants have access to the best available prices at any given time. Where EBBO is supported, market participants' trade orders will be filled at or better than the EBBO price for a given trading instrument.
