Orders are automatically sent to the market when certain user defined conditions are met. In particular, a trader can configure the trading application to automatically send orders for preset quantities at price levels with queues falling below a user defined threshold. The length of queues may be measured in several ways, for example, the queue length could be measured by quantity at a given price level or the queue length could be measured by the number of orders at a given price level, or the queue length could be measured by a combination of quantity and orders. The present embodiments can more quickly recognize opportunities and send an order to take advantage of it than a trader can do manually. Other advantages and features are described herein.
