• receiving by the computing device, from the user via the trading interface, a proximity limit for sending an order to the electronic exchange;
• receiving by the computing device, from the user via the trading interface, a request to trade a spread between the plurality of tradeable objects, the request being received via the price column of the trading interface for a spread price;
• determining by the computing device a price for an order for a first tradeable object of the spread based on the spread price and an inside market of a second tradeable object for the spread;
• generating by the computing device the order for submission to the electronic exchange to trade the first tradeable object;
• determining by the computing device a price range according to the proximity limit for sending an order to the electronic exchange;
• comparing by the computing device the price with the price range;
• and
• automatically submitting by the computing device the order for the first tradeable object for the spread in response to the comparison of the price to the price range.
