Arbitrage (English: arbitrage, also known as arbitrage) usually refers to buying at a lower price and selling at a higher price when there are two prices for a certain physical asset or financial asset (in the same market or in different markets), thus obtaining low-risk income. Arbitrage is risky but not illegal.

2. Futures arbitrage

Futures arbitrage usually means that when a physical asset or financial asset (in the same market or different markets) has two prices, it is bought at a lower price and sold at a higher price, thus obtaining risk-free income. ?

Arbitrage in futures trading means buying and selling two different futures contracts at the same time. Trying to profit from the price difference of the same or similar financial products in different markets or in different forms. Traders buy contracts that they think are "cheap" and sell those "high-priced" contracts at the same time, benefiting from the changing relationship between the prices of the two contracts.

3. Preventive measures

In arbitrage, traders are concerned about the mutual price relationship between contracts, not the absolute price level. The ideal state is risk-free arbitrage. Arbitrage used to be a trading technique used by some alert traders, but now it has developed into a technique to profit from the small price difference of the same securities in different markets with the help of complex computer programs.
