| 20110238594 | COMPUTER IMPLEMENTED AND/OR ASSISTED METHODS AND SYSTEMS FOR PROVIDING RAPID EXECUTION OF, FOR EXAMPLE, LISTED OPTIONS CONTRACTS USING TOXICITY AND/OR PROFIT ANALYZERS - Methods and systems are provided which enable options broker-dealers to execute a listed options contract trade order while simultaneously eliminating (or at least reducing) exposure to the negative consequences associated with toxic (or likely toxic) trades in the options market. By using toxicity and/or profit analyzers, for example, to detect, track and respond to the level of toxic (or likely toxic) orders present in an option contract order flow, a broker dealer can reduce the level of risk inherent in serving as a counter-party in listed options transactions, and inherent in offering a rapid execution guarantee. Various alternative embodiments are also disclosed. | 09-29-2011 |
