Garlic futures. Garlic futures trading refers to the trading with garlic as the subject matter in the futures exchange. The transaction includes buying and selling garlic futures contracts, with a view to delivering garlic at a specific price at a certain time in the future. Futures, completely different from spot, are actually tradable goods (commodities). Futures are mainly not commodities, but standardized tradable contracts with some bulk products such as cotton, soybeans and oil and financial assets such as stocks and bonds as the targets.
