20130066801 | OPTION SPREAD MIDRANGE PROCESSING - Midrange values, which may be, for example, midpoint values, may be derived and provided for use in identifying spread opportunities. A first midrange value disposed between a bid price and a ask price is derived for the first financial instrument. A second midrange value disposed between a bid price and a ask price is derived for a second financial instrument. A computing system then derives from the first and second midrange values a midrange spread value representing a difference between the first and second midrange values. Information identifying the first financial instrument including the first midrange value, information identifying the second financial instrument including the second midrange value, and the midrange spread value are communicated for display. | 03-14-2013 |
