The leverage in futures market is also called leverage principle, which is one of the trading principles in futures market. Speculators can control a large amount of commodity funds with less money. Futures trading only needs to pay margin, and the amount of margin only accounts for a small proportion of the contract amount. Speculators can do bulk futures trading by investing a small amount of principal and paying a deposit. If a trader buys a soybean futures contract (5000 bushels) at a price of 6.5 USD per bushel (the total value of each contract is 3%), the required margin may be 3000 USD, accounting for about 9% of the total contract value, so the trader controls the futures contract with a total value of margin 10 times with little money. Therefore, the futures market has attracted many speculators.

At the same time, speculation in the futures market is risky and profitable. Small changes in futures prices can make some speculators get huge profits after accurate forecasting, while others suffer a lot of losses because of wrong forecasting.
