Understanding the Option Chain and Option Greeks, a look at some of the basic parts of the option chain and option greeks.

OPTION CHAIN

Strike Price: The strike price is the price value that the option is providing the right for. This is what the contract is bound to. This is also primarily how all the different options are categorized. For Example if the strike price is \$37, then the option provides the right to buy (call) or sell (put) at \$37 until it expires.

Expiration: This is simply the length of time the option is provided for and how all the different spreads of strike prices are cataloged. Typically viewed as: 8 DEC 17 100(Weeklys) this means that all the options in this spread expire on December 8, 2017, each contract is for 100 shares, and their classified as "weekly" options.

Expected Move: Is usually found next to the implied volatility at the opposite end of the expiration date, and looks like (+/- .775). This is a constantly changing number based on the current price action and is an estimate of how much the stock is going to move within the expiration of the option. For example if the above expected move was for an option that expired in 3 days then it is estimating the stock is going to move \$.775 within the next 3 days.

Implied Volatility: is typically found next to the expected move at the opposite end of the expiration. This is typically used to estimate the amount of pressure in the stock. Usually fear. A high implied volatility is usually seen as an increased probability of seeing a radical change in the price and investors typically associate it with the stock selling off, but not always.

MARK, BID, ASK, LAST are all the same concepts for an option as they are for a stock. These are the different price tags for the particular option. The Options are always priced as Per Share of the Stock, in other words it is the unit cost, the cost per share, not the cost per contract. To calculate the cost per contract multiply the unit cost by 100.

Volume: The volume is the amount of Option Contracts that have traded so far that day. Calculated similar to stock volume , however when an Option is exercised and not bought/sold it is not counted here. The same concepts in stocks also apply in options apply in terms of liquidity.

Open Interest: This is the running total of the amount of outstanding contracts in the market. This is where the volume goes at the end of the day. When an Option Contract is exercised it however is subtracted from the open interest since the contract is no longer outstanding. The same concepts in stocks also apply in options in terms of liquidity, open interest is just another variable to consider.
