Abstract: A system includes an optical splitter that may receive an optical signal containing trading information from over an exchange network. The optical splitter may split the optical signal at a physical layer into a plurality of signals and transmit the plurality of signals toward a plurality of hosts at a customer end, which may execute transactions using the trading information.

Abstract: A method and system for providing a user with user-friendly handles for manipulating graphics and other displayed objects using a pointer. An initial toolset of handles can evolve into a toolset with enhanced functionality. Selecting an object can invoke a first toolset. Pausing the pointer over an object for a preset length of time can invoke a second toolset with additional functionality. Continuing to maintain the pointer's stationary position over the object can invoke a third toolset. A rotation tool handle can rotate an object about an axis of rotation in response to pointer-based input. Moving a pointer over a rotation tool handles can invoke an axis-of-rotation tool for repositioning the axis of rotation using the pointer.

Abstract: A facility for adapting a subject color to be compatible with a basis color is described. The facility accesses a color transformation specification that specifies how the subject color is to be adapted to be compatible with the basis color. The facility then applies the accessed color transformation specification to the subject color to adapt the subject color to be compatible with the basis color.

Abstract: Methods and systems are provided for bounding data entered into one or more spreadsheet application cells. A bounding function is applied to a given cell that places bounds on values or formula results that may be entered into the cell. If a user enters a value to a bounded cell that exceeds or otherwise violates the bounds applied to the cell, or if a formula directed to the cell evaluates a value to the bounded cell that exceeds or otherwise violates the bounds applied to the cell, the value entered into the cell will be a value most closely approximating the desired value or evaluated value, but that does not exceed or otherwise violate the bounds set for the cell.
