Futures is a contract that must be fulfilled in the future, not a specific commodity. The content of the contract is unified and standardized, but the price of the contract will fluctuate in different sizes due to changes in various market factors.

The "goods" corresponding to this contract are called the subject matter. Generally speaking, the "goods" to be speculated in futures are the subject matter, which is embodied by contract symbols. For example, CU0602 is the symbol of futures contract.

Basic characteristics of futures trading: The basic characteristic of "small and wide" futures trading is that it can be used for large-scale trading with less funds.

For example, with a capital of 500,000 yuan, you can basically do a transaction of about 10 million yuan. That is to say, the trader uses 500,000 yuan as the guarantee (i.e. deposit) for the price change of goods worth 6,543,800 yuan, and the profit and loss generated is borne by the trader's 500,000 yuan, which almost enlarges the fund by 20 times. This is called "leverage effect" or "margin trading".

This mechanism makes futures have the characteristics of "small and wide". Futures trading can be understood as "short selling". Futures trading is a "contract symbol", not buying and selling actual goods. Therefore, when buying and selling futures, traders do not need to consider whether they need or own the corresponding commodities, but only how to buy and sell to earn the difference. The result of buying and selling is only reflected in your own "account", and the price is a handling fee of several ten thousandths and a deposit of about 5%. This can be used simply.
