Silver is a commodity that trades virtually 24 hours per day across many exchanges such as New York, Chicago, London, Zurich and Hong Kong. The most important exchange, however, when it comes to determining the spot silver price is COMEX. The spot price of silver is calculated using the near term futures contract price. By near term, that may mean the front month contract or the nearest contract with the most volume.
