The difference between main connection and continuity
The main contact in futures refers to the contact of main contracts, which refers to the contract with the largest volume or position. Continuity is the price trend of contracts linked together every month.

The main contract in futures refers to the continuity of the main contract, that is to say, the main contract is the mechanical connection of all the main contracts to form a continuous contract, and the daily trading volume and positions are the largest, which will form a relatively continuous K-line chart. Which is the main contract.

The main contract is the connection of the main contracts in different periods, and the index is formed by weighting all contracts according to the volume. Obviously, there is a gap in the main contract because of the month change, and the index is the weight of all contracts, so there will be excellent continuity.

In addition, the main connection must be completed within three months after the agreement is completed on the delivery date.

Futures, whose English name is futures, is completely different from spot. Spot is actually a tradable commodity. Futures are mainly not commodities, but standardized tradable contracts based on some popular products such as cotton, soybeans and oil and financial assets such as stocks and bonds. Therefore, the subject matter can be commodities (such as gold, crude oil and agricultural products) or financial instruments.

The delivery date of futures can be one week later, one month later, three months later or even one year later.

A contract or agreement to buy or sell futures is called a futures contract. The place where futures are bought and sold is called the futures market. Investors can invest or speculate in futures.
