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. 

我們希望這是一節簡單易學的課程，可以向您介紹各種選項。通過閲讀期權基礎知識的文章，你應該能夠理解期權，以及如何利用期權獲利或保護你的股票。

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. 

期權的當前價格稱為其溢價。就是這樣美國政府收到的收入賣方(作者)將期權合同轉讓給另一方。

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

期權溢價是以每股美元和美分作為股票價格，大多數合約代表100股的承諾。

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

那麼，是什麼決定了期權的價格呢？主要由兩個因素組成：固有的和時間(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.

選項包括超時(OTM)只有時間價值，而我N-The-Money期權既有內在價值，又有時間價值。

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.

如果有更多的到期時間和/或更大的隱含波動率，期權的溢價通常會更高。隨着期權臨近到期日，期權的溢價主要來源於內在價值。例如，在一個交易日內到期的深度價外期權通常價值為0美元，或非常接近0美元。
