Futures are delivered before a specific date. For example, a farm in Northeast China planted corn in spring, and the price fluctuated greatly in previous years. In order to protect and stabilize his profits, he now buys this batch of corn in advance and signs a sales contract with the other party (the buyer). There are many contents in the contract, among which quality, quantity, pricing, regular delivery, delivery place and deposit are the core contents. After signing the contract, the farm can get the deposit, which is meaningful. The ownership of this batch of corn harvest is already owned by others, so the advantage of the farm is that the profit has been locked in hard. When the harvest comes, no matter how the price changes at that time, both parties should follow the contract. Okay, I'm tired of writing. In fact, this contract is futures, and futures is actually a sales contract. The technical term is contract.

So what's the difference when combining stocks? This is a big difference. The simple trading method is not copper, futures can buy up or down, two-way trading, T+0 trading, with time limit.
