We study the market quality of the Xetra BEST system operated by Deutsche Börse AG, an internalization system designed as part of an open limit order book, which guarantees a price improvement over the inside spread in the Xetra order book. We develop a structural model of this dual market...

Xetra BEST, operated by Deutsche Borse AG as a part of the Xetra trading system, allows participating banks and brokers to internalize retail customer orders. This paper provides an empirical assessment of the market quality of Xetra BEST. For this purpose, we develop a trade indicator model of...
