Bats BZX Options operates with price-time priority: orders at the best price are filled based on when they were received with the earliest executed first. It offers a maker-taker structure and will be the first U.S. options exchange to use flat pricing, charging 30 cents per contract to all liquidity takers and giving a rebate of 20 cents per contracts to all market makers, who add liquidity. 
EDGX Options is based on a customer priority/pro rata allocation model and is designed to complement Bats' BZX Options market.
In its first year of trading, Bats Options was ranked as the world's 36th-largest derivatives exchange by volume in 2010, according to the annual volume survey published by the Futures Industry Association (FIA). The FIA report, published in March of 2011, notes that the exchange's total volume for the year was about 25.1 million contracts.
