A system and method are provided for defining slop parameters to an individual spread order or a customized group of orders. The system and method may be used to, for example, define inside slop, outside slop, and/or adjustable range parameters to one or more orders. The inside slop, outside slop, and/or adjustable range parameters may be input by a trader, and, among other things, allow a trader to prioritize orders, set parameters so that some orders are re-priced more aggressively than other spread orders. Alternatively, slop parameters associated with a spread order may also apply more restrictive slop parameters to orders within the same adjustable range. Slop parameters associated with a spread order can also be configured and modified by a trader based on the trader's preferences. Other features and advantages are described herein.
