中文：

期货合约为什么要平仓？这是许多期货交易者经常遇到的问题。期货交易是一种金融衍生工具，其核心价值在于为交易者提供一种风险管理和价格发现的机制。然而，在期货交易中，平仓是一个至关重要的环节，其背后有多重原因。

首先，平仓是期货合约生命周期中的必要步骤。期货合约通常都有一个固定的到期日，到了这个日期，合约就会失效。因此，交易者需要在到期前选择平仓，以避免合约过期带来的风险。

其次，平仓也是交易者进行风险管理的一种方式。在期货交易中，市场波动可能导致交易者的账户面临损失。当损失达到一定的程度时，交易者可以选择平仓，以限制进一步的损失。

此外，平仓还可以帮助交易者锁定利润。当市场行情有利于交易者时，他们可以选择在合适的时机平仓，以锁定已获得的利润。这样可以避免市场波动导致的潜在损失。

综上所述，期货合约平仓的原因主要包括合约到期、风险管理和锁定利润等。对于期货交易者来说，掌握平仓的时机和策略是成功的关键。

Why is it necessary to close out futures contracts? This is a question that many futures traders often encounter. Futures trading is a financial derivative instrument, whose core value lies in providing traders with a mechanism for risk management and price discovery. However, closing out positions is a crucial aspect of futures trading, driven by multiple reasons.

Firstly, closing out is a necessary step in the lifecycle of a futures contract. Futures contracts typically have a fixed expiration date, upon which the contract becomes void. Therefore, traders need to choose to close out their positions before expiration to avoid the risks associated with expired contracts.

Secondly, closing out is also a way for traders to manage risk. In futures trading, market fluctuations can expose traders' accounts to losses. When losses reach a certain level, traders can choose to close out their positions to limit further losses.

In addition, closing out can help traders lock in profits. When market conditions are favorable to traders, they can choose to close out their positions at an appropriate time to lock in the profits earned. This can avoid potential losses caused by market volatility.

In conclusion, the reasons for closing out futures contracts mainly include contract expiration, risk management, and profit locking. For futures traders, mastering the timing and strategy of closing out is crucial to success.
