1. Two-way trading: futures can be bought long or sold short. When the price rises, you can buy low and sell high, and when the price falls, you can sell high and buy low. You can make money by doing more, and you can also make money by shorting.

2. Intra-day liquidation: T+0 trading system is implemented in futures trading, and the purchased contract can be liquidated on the same day. If it's profitable, it can be pocketed immediately.

3. Margin leverage: When buying and selling futures contracts, investors do not need to pay all the funds of the contract value, but only need to pay a margin of 5%- 15% to complete the contract transaction, which can be understood as small and broad.
