1. Futures are things that are traded in the form of contracts, and the trading objects are mainly sales contracts. Futures are divided into commodity futures and stock futures. At present, there is no stock futures in China.

2. Spot is cash spot, and futures are contract transactions, that is, mutual transfer of contracts. There is a time limit for futures delivery. Before the expiration, it is a contract transaction, but the expiration date is to cash the contract for spot delivery. Therefore, large futures institutions often do both spot and futures, which can be used for hedging and speculation. Ordinary investors often can't deliver in time, so they have to speculate purely, and the speculative value of commodities is often related to factors such as spot trend and duration of commodities.

3. Futures trading is a kind of contract trading, and you only need to pay the deposit of the actual price of the corresponding commodity for each transaction. The specific margin ratio is determined by the futures exchange according to market conditions, and the futures company will also make adjustments.
