Option Chain

Unlike a stock that has a single consolidated bid and ask quote, options on a stock come in many different flavors. There are puts and calls, different strikes and different expiration months on many option contracts. Given that there can be hundreds or even thousands of different option contracts available for trading on the same underlying asset, it can be challenging to organize them all into a coherent presentation where they can be compared side by side. The typical approach is to display options in a table which contains all options for a given expiration. This is called the Option Chain or the Option Montage.

To view the Option Chain for a specific symbol, enter it in the field below and click "View Option Chain". If your symbol is not visible in the drop-down, it's likely that there aren't any options available for the chosen symbol.

Working With the Option Chain On Market Chameleon


Diagram of Market Chameleon Option Chain

Market Chameleon's Option Chain presents a wealth of information to the user without it becoming overwhelming. A specific row in the option chain table contains call and put information for a given strike. The call is displayed on the left and the put on the right. The strike price is displayed prominently in the middle - between the call information and the put information. This presentation makes it easy to see the call and corresponding put side by side and view the strikes going up by ascending order. The At-The-Money strikes are enclosed in a black frame.

The pre-defined columns in the Option Chain are volume, bid implied vol, bid quote ask quote and ask implied vol. There is also a customizable column on the left and right margins that can display Open Interest, Vega, Delta, IV Chg or Mkt Chg according to the user's choice made using the drop-down in the column header.

Clicking on a value in the "Volume" column brings up a detail screen that shows the trade details for that specific contract. More on this below...

Clicking on a value in the "Strike" column brings up a detail screen that shows the implied volatility graphs for that strike. More on this below...

Choosing the Expiration Date and Option Root


Expiration and root selector for Option Chain

The table on the right side allows the user to select a different expiration which will cause the option chain table to be re-drawn for another expiration. To the right of the expiration date there may appear the letter "E" indicating upcoming earnings or "D" indicating upcoming dividends. Hovering over the "E" or "D" brings up details about the event.

In rare cases the user might see more than one option root choice. There are a handful of stocks that have a special option contract available called a "Mini". While a standard option contract gives the holder the right to buy or sell (depending on contract type) 100 shares of the underlying stock, a Mini contract reduces quantity of underlying to just 10 shares.
