期权计算

流程：

1. 每天上传交易记录，分配到交易组合里，系统转换成头寸 https://mafint.atlassian.net/wiki/spaces/MCUGC/pages/1930395649

2. 在专属行情价格里维护并保存当日标的收盘价的价格 https://mafint.atlassian.net/wiki/spaces/MCUGC/pages/1952972914

3. 通过期权计算板块计算期权的价格，保存到专属行情价格里 https://mafint.atlassian.net/wiki/spaces/MCUGC/pages/2066153473

4. 剩下的，系统就会根据保存的价格，波动率，Greeks来计算 P/L，头寸等

期权计算板块能够使用特定的期权定价模型来计算期权合约在某一结算日期下的价格及其风险指标。

1. 请点击左侧导航栏中的 成交明细 下拉菜单中的 金融衍生品交易

再点击 期权计算 板块

2. 请参考步骤3来了解如何使用期权计算功能。此外，您也可以按如下步骤来手动录入：

请点击+ 新交易按钮手动输入数据。所有红色字段均为必填项。为了区分自动填写的未平仓合约（参考第3点）和手动输入的行，当您点击+ 新交易以输入数据时，新添加的行将显示绿色边框。

TTM: The number of days from the settlement date to the last trading day of all trading days (excluding weekends), you may edit as necessary
POC: The total number of trading days of the selected option contract in the expiry month, you may edit as necessary
DELTA : Delta value represents the fluctuation of the option price or option premium due to the change of the underlying futures price.
GAMMA : Gamma value is defined as how Delta itself changes with the change of the underlying futures price. Please regard Gamma as the Delta of Delta.
THETA : Theta measures the sensitivity of an option to time. Theta is usually expressed as a negative number.
VEGA : Vega is used to measure the sensitivity of an option to implied volatility.

Once all required fields are filled, please tick the row and click on Save Changes at the bottom left of the page to save your data into the Proprietary Market Data page. You may proceed to the Market Data>Proprietary Market Data table to view your saved options data (settlement price, DELTA , GAMMA , THETA , and VEGA obtained through the option calculation formula)

Step 5: Set the Option Pricing Formula

Please select the pricing formula from the Option Pricing Formula drop-down list. Only TURNBULL-WAKEMAN ASIAN is available, if other formulas are required, please contact us at support@mafint.com.

TURNBULL-WAKEMAN ASIAN介绍：

亚洲期权价格计算的一种常用模型, Turnbull–Wakeman 公式是连续算术平均利率期权的著名公式。

在亚洲期权频繁交易的许多商品和能源市场中，平均值通常基于期货或远期价格，也就是说，标的资产的持有成本为零，同时当连续股息收益率等于无风险利率时，股票期权的持有成本也可以为零。

Turnbull-Wakeman 不仅为持有成本不为零的亚式期权开发，也可以扩展到持有期货期权（持有成本为零）。

2017 年，欧洲能源交易所宣布他们已从使用 Black-76 公式（Black 1976）结算货运期货期权，转而使用 Turnbull-Wakeman 公式，从 2018 年开始，欧洲能源交易所一直在根据 Turnbull-Wakeman 公式结算货运期货期权和铁矿石期权。

The Turnbull–Wakeman formula is a well-known formula for continuous arithmetic average rate options.

In many commodity and energy markets where Asian options frequently trade, the average is typically based on futures or forward prices, that is to say, the cost-of-carry for the underlying asset is zero. Options on stocks can also have a cost-of-carry of zero. If the continuous dividend yield is equal to the risk-free rate, then the extension given in this note can be used in that case as well.

Turnbull-Wakeman was developed not only for Asian options with non-zero holding costs, but can also be extended to hold options on futures (with zero holding costs).

In 2017, the European Energy Exchange announced that they had switched from using the Black-76 formula (Black 1976) for settling freight futures options to the Turnbull–Wakeman formula. From 2018 on, the European Energy Exchange has been settling both freight futures options and iron ore options based on our modified Turnbull–Wakeman formula.
