Abstract: An electronic trading system utilizes a Match Engine that receives orders, stores them internally, calculates tradable combinations and advertises the availability of real and implied orders in the form of market data. New tradable items defined as combinations of other tradable items may be included in the calculation of tradable combinations. The disclosed embodiments relate to detection of market conditions where identification of implied opportunities may, for example, subvert real orders resulting in undesirable effects. Under circumstances where such undesirable effects are likely to occur, identification of implied opportunities may be delayed thereby allowing market forces to attempt to resolve the aberrant market conditions and avoid the undesirable effects.
