Derivatives markets can be standardized (many users trading fungible contracts, typically on an exchange) or non-standardized (where derivitives are customized for the user by a trading desk - the over-the-counter market). One derivatives market is for standardized stock options, a market where parties can buy or sell, call or put options on a secondary market. Non-standardized derivatives instruments,such as naked warrants issued directly by financial institutions to a secondary market, also exist.
Other derivative markets include those for Interest Rate Swaps, Credit Default Swaps and Options and forwards on foreign exchange.
