Abstract: A sheath has a sheath body having a front plate and a back plate spaced apart from the front plate. The front plate and back plate define a cavity within the sheath body. The cavity is externally accessible through an opening formed between the front plate and the back plate. Snapping fasteners are positioned about a front side and a back side of the back plate. The snapping fasteners each include a male component and a female component. The male component and female component of each fastener are mounted on opposite sides of the back plate. The male component includes a protrusion extending away from the sheath body. The female component defines a recess that is complimentary to the protrusion.

Abstract: A computer-implemented method for trading a financial instrument. The method can include receiving an instrument designation for a financial instrument, receiving an offset value, related to the instrument, and receiving an actuation of at least one of a better buyer selector and a better seller selector related to the instrument. The method can include receiving a base value related to the instrument, receiving a timeout rule related to the instrument, and receiving a timeout value related to the instrument. The timeout rule can be an interval type, and the timeout value can be a time interval. The timeout rule can be a custom type, and the timeout value can be a mathematical expression. In addition, the method can include generating a request to buy the instrument at a value of the offset above the bid price for the instrument, and buying the instrument.
