Bats, the market for exchange-traded fund (ETF) trading, has announced the planned introduction of the Bats ETF Implied Liquidity Feed, which provides investors with a critical reference view of ETFs versus their underlying securities.

The feed, which is the first of its kind and is filed and pending publication by the Securities and Exchange Commission, measures the implied liquidity of a fund using select data points, which includes information regarding the ETF's underlying securities. The feed includes a proprietary calculation of the fund's implied liquidity and the aggregate best bid and offer of all displayed orders across the four Bats equity exchanges.

This has a range of uses throughout the ETF trading lifecycle. Pre-trade, the feed allows investors to understand the true liquidity picture when selecting investable ETFs, and better estimate trading costs before placing orders. During trading, the feed will allow investors to adjust limits to enhance the probability of orders being filled, and evaluate block-trading proposals in real-time, knowing where to trade in size. Post trade, investors can use the feed as a reference to measure trades against historical implied quotes and size. In analyzing the data, investors can optimize their approach to trade at liquidity peaks.

Accordingly, the feed gives an accurate representation of the true value of an ETF intraday, distinct from other common metrics, like average daily volume (ADV) or Net Asset Value (NAV).

Kevin Carrai, Vice President, Market Data and Access Services said: "Bats' ongoing mission is to increase transparency and market participation, and we believe that the Implied Liquidity Feed will help promote both in the ever-expanding U.S. ETF market. As with the Bats One feed, which we enhanced last year, the Implied Liquidity Feed is designed to support many types of customers from institutional to everyday investors, and will be accessible via direct exchange feeds and through our distribution partners."
