We are hoping this to be an easy and simple lesson to introduce options to you. By following Options Basics' articles, you should be able to understand options and how to utilize options to either profit or protect your stock. 

我们希望这是一节简单易学的课程，可以向您介绍各种选项。通过阅读期权基础知识的文章，你应该能够理解期权，以及如何利用期权获利或保护你的股票。

The current price of an option is called its premium. It is thus the income received by the seller (writer) of an option contract to another party. 

期权的当前价格称为其溢价。就是这样美国政府收到的收入卖方(作者)将期权合同转让给另一方。

An option premium is stated in dollars and cents per share as its stock price, and most contracts represent the commitment of 100 shares.

期权溢价是以每股美元和美分作为股票价格，大多数合约代表100股的承诺。

So what determines the price of options? Mainly composed of two factors: intrinsic and time(extrinsic) value.

那么，是什么决定了期权的价格呢？主要由两个因素组成：固有的和时间(外部)值.

Options that are out-of-the-money(OTM)only have time value, while in-the-money options have both intrinsic and time value.

选项包括超时(OTM)只有时间价值，而我N-The-Money期权既有内在价值，又有时间价值。

An option's premium will generally be greater given more time to expiration and/or greater implied volatility. As the option approaches its expiration date, the option's premium stems mainly from the intrinsic value. For example, deep out-of-the-money options that are expiring in one trading day would normally be worth $0, or very close to $0.

如果有更多的到期时间和/或更大的隐含波动率，期权的溢价通常会更高。随着期权临近到期日，期权的溢价主要来源于内在价值。例如，在一个交易日内到期的深度价外期权通常价值为0美元，或非常接近0美元。
