Barchart allows you to view options by Expiration Date (select the expiration month/year using the dropdown menu at the top of the page).Weekly expiration dates are labeled with a (w) in the expiration date list.
Options information is delayed 15 minutes.
Select an options expiration date from the dropdown list at the top of the table, and select "NeartheMoney" or "Show All' to view all options.
Note: Option quotes with an asterisk * after the strike price are "restricted options", typically created after spinoffs or mergers.
You can also view options in a StackedorSidebySideview. The View setting determines how Puts and Calls are listed on the page. For both views, "NeartheMoney" Calls and Puts are highlighted:
NeartheMoney  Puts: Strike Price is greater than the Last Price
NeartheMoney  Calls: Strike Price is less than the Last Price

For the selected Options Expiration date, the information listed at the top of the page includes:
 Options Expiration: The last day on which an option may be exercised, or the date when an option contract ends. Also includes the number of days till options expiration (this number includes weekends and holidays).
 Next Earnings Date: The next reported earnings date. Stocks whose Next Earnings Date falls within the next 7 days are highlighted in red.
 Next ExDividend Date: Shareholders on record as of this date are entitled to any dividend paid.
 Implied Volatility: The average implied volatility (IV) of the options contract that is 30days or more out. IV is a forward looking prediction of the likelihood of price change of the underlying asset, with a higher IV signifying that the market expects significant price movement, and a lower IV signifying the market expects the underlying asset price to remain within the current trading range. IV is calculated based on the last price for today, if no last then the midpoint between the bid/ask assuming it exists for today.
 Historic Volatility: The 30day historic volatility for the underlying asset. Historic volatility is the standard deviation of the "price returns" over a given number of sessions, multiplied by a factor (260 days) to produce an annualized volatility level.
Stacked View
AStackedview lists Puts and Calls one on top of the other, sorted by Strike Price.
 Strike: The price at which the contract can be exercised. Strike prices are fixed in the contract. For call options, the strike price is where the shares can be bought (up to the expiration date), while for put options the strike price is the price at which shares can be sold. The difference between the underlying contract's current market price and the option's strike price represents the amount of profit per share gained upon the exercise or the sale of the option. This is true for options that are in the money; the maximum amount that can be lost is the premium paid.
 Moneyness the percent from the last price: (strike price  last / last). Moneyness refers to the relative position of the underlying asset's last price to the strike price. When a call option's Moneyness is negative, the underlying last price is less than the strike price; when positive, the underlying last price is greater than the strike price. When a put option's Moneyness is negative, the underlying last price is greater than the strike price; when positive, the underlying last price is less than the strike price.
 Bid: The bid price for the option.
 Midpoint: The midpoint between the bid and ask.
 Ask: The ask price for the option.
 Last: The last traded price for the options contract.
 Change: The difference between the current price and the previous day's settlement price.
 %Change: The difference between the current price and the previous day's settlement price, expressed as a percent.
 Volume: The total number of option contracts bought and sold for the day, for that particular strike price.
 Open Interest: Open Interest is the total number of open option contracts that have been traded but not yet liquidated via offsetting trades for that date.
 Open Interest Change: The change in open interest from the previous session.
 Delta  measures the sensitivity of an option's theoretical value to a change in the price of the underlying asset.
 Implied Volatility  Implied Volatility (IV) is the estimated volatility of the underlying stock over the period of the option. IV can help traders determine if options are fairly valued, undervalued, or overvalued. It can therefore help traders make decisions about option pricing, and whether it is a good time to buy or sell options. Implied volatility is determined mathematically by using current option prices in a formula that also includes Standard Volatility (which is based on historical data). The resulting number helps traders determine whether the premium of an option is "fair" or not. It is also a measure of investors' predictions about future volatility of the underlying stock.
SidebySide View
ASidebySideView lists Calls on the left and Puts on the right.
 Last: The last traded price for the options contract.
 %Change: The difference between the current price and the previous day's settlement price, expressed as a percent.
 Bid: The bid price for the option.
 Ask: The ask price for the option.
 Volume: The total number of option contracts bought and sold for the day, for that particular strike price.
 Open Interest: Open Interest is the total number of open option contracts that have been traded but not yet liquidated via offsetting trades for that date.
 Strike: The price at which the contract can be exercised. Strike prices are fixed in the contract. For call options, the strike price is where the shares can be bought (up to the expiration date), while for put options the strike price is the price at which shares can be sold. The difference between the underlying contract's current market price and the option's strike price represents the amount of profit per share gained upon the exercise or the sale of the option. This is true for options that are in the money; the maximum amount that can be lost is the premium paid.

 Put/Call Volume Ratio: Put Volume Total / Call Volume Total.
