1. A method for trading in an electronic trading environment comprising:

  • defining by a computing device a first spread strategy comprising a first tradeable object and at least one second tradeable object;

    defining by the computing device a second spread strategy comprising the first tradeable object and at least one third tradeable object;

    computing by the computing device a first price to buy or sell the first tradeable object, wherein the first price is computed based on market conditions corresponding to the at least one second tradeable object and further based on a desired spread price for the first spread strategy;

    sending by the computing device a first order to buy or sell the first tradeable object at the first price to be placed in an order book of a computerized matching process, wherein the first order satisfies the desired spread price of the first spread strategy;

    automatically sending by the computing device a plurality of queue holder orders to buy or sell the first tradeable object at a plurality of prices to be placed in the order book of the computerized matching process, wherein the plurality of queue holder orders are assigned to the first spread strategy and the plurality of prices are based on the first price of the first order corresponding to the first spread strategy, and wherein the plurality of queue holder orders do not satisfy the desired spread price of the first spread strategy;

    determining by the computing device that the first order no longer satisfies the desired spread price of the first spread strategy subsequent to the placement of the first order and the plurality of queue holder orders;

    using by the computing device a queue holder order of the plurality of queue holder orders for the first spread strategy instead of the first order when a second price of the queue holder order satisfies the desired spread price; and

    when the queue holder order corresponding to the first spread strategy is filled, assigning by the computing device remaining queue holder orders of the plurality of queue holder orders to be used by the second spread strategy.
