Forward trading is conducted on stock exchanges. The stock exchange is an organized trading venue whose main function is to meet the supply and demand of securities, goods and services under equal conditions for all participants. Derivatives are essential items of futures, and they can be divided into options, swaps and futures. An option is a contract that gives the owner the right, not the obligation, to sell or buy a financial or real asset by a certain date at a pre-agreed price. Currency swaps and interest rate swaps stand out when exchanging. Currency swap eliminates the risk of loss during a change in the exchange rate, while interest rate swap protects against loss during a change in the interest rate. Forward contracts are contracts for the sale of an asset, commodity or financial instrument at a future time. Forward contracts are the most common subject of futures trading.
