1. The derivative financial instrument market turns the trading of prototype financial assets into futures contracts, and the selectivity of performance or non-performance of buying and selling certain financial assets into tradable goods; Therefore, the object of derivative financial instruments market transactions is the contract, not the subject matter stipulated in the contract.

2. The price of each derivative financial instrument traded in the derivative financial instrument market is limited by the spot market price of the prototype financial asset on which it is based. For example, the change of stock index affects the price of stock index futures.

3. The operating mechanism of derivative financial instruments out of the market is characterized by high financial leverage, that is, traders must pay a certain percentage of margin or insurance premium to enter the market, and the contract value of the transaction is dozens of times that of margin or insurance premium. Entering traders take this opportunity to "play more with less" and manage exchange rate and profit risk at lower cost. Due to the frequent fluctuation of exchange rate and interest rate, it is also convenient for speculators to obtain speculative profits.
