An electronic trading method is provided. The method includes receiving a trading strategy order having a parent trading strategy including multiple quoting legs; splitting the trading strategy order into multiple child orders; and submitting each of the multiple child orders to exchange systems adapted to fill the quoting legs in the child orders. Each child order includes a child trading strategy having a single quoting leg or a reduced number of quoting legs relative to the parent trading strategy. The child trading strategies are the same as the parent trading strategy except for the number of legs marked as quoting legs. The method may be performed by a trading strategy device disposed between a client device and multiple server side devices.
