Because the quantity in futures includes buying quantity and selling quantity, there is only buying quantity in stocks, so obv is not very accurate compared with stock chain and futures. It is recommended to look at the position analysis, which is more suitable for futures.

Futures and spot are completely different. Spot is actually a tradable commodity. Futures are mainly not commodities, but standardized tradable contracts with certain mass products such as cotton, soybeans and oil and financial assets such as stocks and bonds as the targets. 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. Most people think that improper speculation in futures, such as short selling without goods, will lead to financial market turmoil, which is not correct. Going long and shorting at the same time is a healthy and normal trading market.
