Futures accounts are basically opened online, and you need to prepare the original ID card, bank card and signature photo. Mobile phone operation is enough. After opening an account, you can trade the relevant bank period. As long as you open an account in a regular futures company, the funds are safe. You don't need a contract lock at all.
In futures trading, futures locking is an important content. Futures lock-up generally refers to an operation mode in which futures traders open positions in the opposite direction in equal amount. Lock-in generally refers to an investor opening a new position opposite the original position after buying and selling the contract. Under normal circumstances, no matter where the futures price rises or falls, the profit or loss of the position will not increase or decrease.
