What Is The Options Chain?

While the movie “The Matrix” isn’t quite real, looking at the options chain might be the next closest thing for a new options trader. At a quick glance, the options chain may look a bit overwhelming.

Options Expiration Date

When initially viewing the options chain, the options contracts will are sorted by expiration date. If you want to see the strike prices for a contract on any maturity date, clicking the drop-down arrow on the left side will expand the options chain. Some stocks have daily, weekly, and monthly expiration dates. Contracts like SPY, SPX, NDX, and other high-volume ETFs will have more expiration dates. 

Strike Price

The strike price or the agreed-upon price can be found in the center of the list. Some option contracts will have strike prices in $2.50, $5.00, and $10.00 dollar intervals. This depends on the share price and the volume of that specific contract. 

Calls vs. Puts

The thinkorswim options chain is broken into two main sections, divided by the strike price in the center. The left section of the list is allocated to calls, and the right portion of the list is allocated to puts. As a brief recap, a call option contract provides the owner with the option to buy 100 shares of the underlying asset at an agreed-upon price anytime before expiration. A put option contract gives the buyer the right to sell 100 shares of the underlying asset, at an agreed-upon price, before the contract expiration.
