A bone spur (osteophyte) is a bony growth formed on normal bone. Most people think of something sharp when they think of a spur, but a bone spur is just extra bone. It's usually smooth, but it can cause wear and tear or pain if it presses or rubs on other bones or soft tissues such as ligaments, tendons, or nerves in the body.
An immediate or cancel order (IOC) is an order to buy or sell a security that must be executed immediately, and any portion of the order that cannot be immediately filled is cancelled.
There are several federal laws (known as cooling-off rules) that allow you to cancel certain contracts within a few days of signing them. They apply to contracts made during door-to-door or trade show sales, contracts for home equity loans, or delayed mail order or Internet purchases.
