期权的理论研究可以分为期权定价、交易策略和风险管理三个方面，其中，期权定价是交易策略和风险管理的理论基础。我们 从定价的角度来看，期权的价格变动可以用以下数学公式表示： $\Lambda V_{\rm option}\approx delta\cdot\Delta S+\frac{1}{2}$_gamma$\cdot\Delta S^{2}-$theta$\cdot\Delta T+$vega$\cdot\Delta\sigma+$rho$\cdot\Delta r$_ 由于利率变动较小，对期权的价格影响较为有限，剩下四个较为重要的研究维度分别是方向（delta）、加速度（gamma）、波 动率(vega)和时间价值(theta)，这四个维度可以解释大部分期权价格的变化。虽然从数学的角度看还有更为高阶的分解，但是高 阶部分对期权的价格影响较小，这里不再做更细微的分析。 在金融市场中，期权策略对于各类市场参与者具有重要的实践意义和价值。期权交易策略为投资者提供了灵活的投资方式，合 理运用期权策略可以有效实现风险管理，优化资产配置，增强投资收益。本文系统梳理了期权策略的四个核心维度及其相互关 系，构建了期权波动率 ...

However, they often face risk exposure due to unequal market buying and selling forces, and effective risk management is the core issue for them [2][4]. - Market makers use volatility strategies to manage risks and achieve profits.

But they often have net long or short positions, leading to risk exposure [2]. - Market makers manage risks by monitoring and adjusting Greek letters (Delta, Gamma, Vega). They use underlying assets or other options to hedge risk exposures, and need to consider factors such as liquidity and operational risk [3]. - Market makers use volatility strategies. When expecting rising volatility, they can use long volatility strategies like Long Straddle and Long Strangle; when expecting falling volatility, they can use short volatility strategies like Short Straddle and Short Strangle.
