期货和期权是金融市场中常见的衍生品，有着各自独特的特点和功能。在期货和期权交易中，有许多术语是投资者需要了解的。本文将介绍一些常见的期货期权术语的中英对照，以帮助投资者更好地理解和应用这些术语。

1. 期货（Futures）

期货是一种标准化的金融合约，约定在某个未来时间以约定的价格买进或卖出标的资产。期货合约的标的资产可以是大宗商品、股指、外汇等。期货市场是一个集中交易场所，投资者通过期货合约进行买卖，可以实现对冲风险、套利交易等目的。

Futures - Futures are standardized financial contracts that agree to buy or sell an underlying asset at an agreed price in the future. The underlying asset of a futures contract can be commodities, stock indices, foreign exchange, etc. The futures market is a centralized trading venue where investors trade futures contracts to hedge risks, arbitrage, and other purposes.

2. 期权（Options）

期权是一种金融衍生品，授予持有者在未来某个时间以约定价格买入或卖出标的资产的权利，但并非义务。期权有两种类型，即认购期权（Call Options）和认沽期权（Put Options）。期权交易可以为投资者提供灵活的风险管理工具和投机机会。

Options - Options are financial derivatives that give the holder the right to buy or sell the underlying asset at an agreed price in the future, but not the obligation. There are two types of options, namely Call Options and Put Options. Options trading can provide investors with flexible risk management tools and speculative opportunities.

3. 行权价（Strike Price）

行权价是期权合约约定的买入或卖出标的资产的价格。对于认购期权，行权价是buy标的资产的价格；对于认沽期权，行权价是卖出标的资产的价格。行权价在期权合约中起着至关重要的作用，影响期权的实值与虚值情况。

Strike Price - The strike price is the price at which the underlying asset is bought or sold in the option contract. For Call Options, the strike price is the price at which the underlying asset is purchased; for Put Options, the strike price is the price at which the underlying asset is sold. The strike price plays a crucial role in the option contract, affecting the in-the-money and out-of-the-money situations of the option.

4. 到期日（Expiration Date）

到期日是期权合约规定的最后交易日，持有者在到期日前可以行使期权合约。到期日对于期权持有者来说是一个重要的时间节点，决定着期权合约是否能够获利。到期日过后，期权合约将自动结算，持有者失去行使期权的权利。

Expiration Date - The expiration date is the final trading day specified in the option contract, and the holder can exercise the option contract before the expiration date. The expiration date is an important time point for option holders, determining whether the option contract can make a profit. After the expiration date, the option contract will be automatically settled, and the holder loses the right to exercise the option.
