Routing equivalent listings across competing exchanges

When a listing is no longer exclusive

Competing marketplaces have multiplied worldwide and have begun listing one another’s products, so a given trading opportunity can appear in more than one place.

A marketplace is no longer defined by a national border or a trading floor. It can exist as remote infrastructure rather than a physical location.

An equivalent listing is the same or closely substitutable product offered on more than one marketplace. An execution venue is a marketplace that lists the instrument and can receive, match, and document the order.

How execution venues differ

Marketplaces differentiate themselves through the products they list, the activity they attract, how quickly they handle orders, how they price access, and the protections they offer participants.

Wider choice among destinations has been described as putting downward pressure on transaction costs and ending exclusive control of listings by a single marketplace.

Sending directed flow to a chosen venue

Order routing means sending an executable order to a chosen marketplace after comparing available listings, activity, speed, and trading cost.

After identifying which marketplaces list a given instrument, the next step is to review that venue’s contract and trading details before the order is sent.

One routing practice is to maintain access to equivalent products on more than one marketplace and confirm that the broker can send the order to the selected destination. Directed flow is an instruction that the broker send the order to a specified venue rather than leaving the destination implicit.

Implementation cost is the cost of getting the order filled at the chosen venue, including access pricing and the quality of that destination.

Records that can reconstruct a dispute

Thorough trade records matter because they let later disputes be reconstructed against a documented sequence of events. Trade documentation supplies those records for the chosen execution venue.
