Perpetual contract is a kind of financial derivative, similar to traditional futures contract. The biggest difference is that perpetual contracts have no expiration date and settlement date, and users can hold positions indefinitely. In other words, as long as there is no liquidation, it will not stop.

In addition, perpetual contracts are long-term, volatile and risky, and careless operation may lead to short positions. All investors should pay attention to risks when trading perpetual contracts, and the following points can be referred to in the trading process:

1. No-day trading: Daily trading will generate transaction costs and increase transaction costs.

2. Follow the trend: When trading, follow the trend and don't go against the trend.

3. Control positions: Don't trade too heavily, resulting in big losses.
