The most common way to trade on commodities is through a futures contract, which is an agreement to buy or sell a specific amount of a commodity at a fixed sum at a pre-determined point in the future. With some commodities, like gold and silver, it’s possible to trade a daily cash market (Rolling Daily), but for the bulk of tradeable commodities we are operating in the futures market.
On the ETX Capital TraderPro platform you will find a list of all the commodities you can trade on. Usually there are futures contracts for the next one or two months, with an expiry day (when the contract is settled).
