A trading system is described herein for hosting a collection of one or more electronic exchanges. The collection of electronic exchanges may be made up of separately designated exchanges under one or more authorizing and regulating bodies. The trading system receives from traders bids to purchase and offers to sell a tradeable object listed at one of the electronic exchanges. Then, the trading system directs the bids and offers to the appropriate exchange where the bids and offers may be automatically matched in the corresponding market. The trading system may also be used to take actions in one or more markets that are internal and external to the trading system on behalf of a trader using preprogrammed trading instructions.
