The Options Clearing Corporation (OCC) uses this procedure to exercise in-the-money options at expiration. Doing so protects the owner of the option from losing the intrinsic value of the option because of the owner's failure to exercise. Unless instructed not to do so by the owner of the option (through the owner's broker), The Options Clearing Corporation will exercise all expiring equity options that are held in customer accounts if they are in-the-money by .01 or more. Thinkorswim will automatically exercise an option position if it is .01 or greater in-the-money at expiration unless the owner of the option instructs otherwise.
A rather arbitrary term that refers to the classes of options with the expiration months that are further dated than the option class with the nearest expiration month.

A mathematical model used to price options. Generally used for American-style options, the model creates a binomial lattice to price an option, based on the stock price, strike price, days until expiration, interest rate, dividends, and the estimated volatility of the stock. One of the main differences from the Black Scholes Model is that it factors in the possibility of early exercise of the options.
Black Scholes Model:
A mathematical model used to price options. Generally used for European-style options, the model prices options using a probability-weighted sum of stock and a bond. Black-Scholes uses the stock price, strike price, days until expiration, interest rate, dividends, and the estimated volatility of the stock as variables in the model.

For example, a long 50/60 box spread would be long the 50 call, short the 50 put, short the 60 call and long the 60 put. Considered largely immune to changes in the price of the underlying stock, in most cases, a box spread is an interest rate trade. For all intents and purposes, the buyer of the box is lending money to the options market, and the seller of the box is borrowing money from the options market.
Break -Even Point(s):
The stock price(s) at which an option position generates neither a profit nor a loss. An option position's break-even point(s) are generally calculated for the options' expiration date. Option pricing models can be used to calculate a position's break-even point before the options' expiration date.

A call option gives the buyer of the call the right, but not the obligation, to buy the underlying stock at the option's strike price. The seller of the call is obligated to deliver (sell) the underlying stock at the option's strike price to the buyer of the call when the buyer exercises his right.
The term used when the seller of a call option is obligated to deliver the underlying stock to the buyer of the call at the strike price of the call option.
An investor who receives a premium and takes on, for a specified time period, the obligation to sell the underlying security at a specified price at the call buyer's discretion.
An order to buy or sell stock or options that is canceled before it has been executed. Generally, it is easier to cancel a limit order than a market order.

Often another term for synthetic stock, a combo is an option position composed of calls and puts on the same stock, same expiration, and typically the same strike price. The quantity of long options and the quantity of short options nets to zero. Buying a combo is buying synthetic stock; selling a combo is selling synthetic stock.

For example, a long 50/55/60/65 call condor is long 1*50 call, short 1*55 call, short 1*60 call, and long 1*65 call. In a long (short) condor the highest and lowest strikes are both long (short) while the two middle strikes are both short (long).

The number of shares of the underlying stock that an options contract would deliver if exercised. Contract sizes for equity options in the U.S. are generally 100 shares, unless the contract size has been adjusted for a split, merger, or spin-off. For example, if you are long 1 XYZ 50 call with a contract size of 100 and you exercise that call, you will get 100 shares of XYZ for a price of $50 per share. If you are long 1 ABC 90 call with a contract size of 250 and you exercise that call, you will get 250 shares of ABC for a price of $90 per share. Thinkorswim incorporates the contract size in the calculation of your delta and gamma.
A position of long stock, short a call, and long a put (with the call and put having the same strike price, expiration date, and underlying stock). The short call and long put acts very much like short stock, thus acting as a hedge to the long stock. So, a conversion has a very small delta. A conversion is a way to exploit mispricings in carrying costs.

When referring to stock options, delivery is the process of delivering stock after an option is exercised. If a trader is long a call, and he exercises that call, the person who is short that call must deliver the underlying stock to the trader who is long the call. If a trader is long a put, and he exercises that put, the trader will deliver the underlying stock to the person who is short that put. Actually, the delivery of the stock takes place through clearing firms under very specific terms and procedures established by the exchange where the option is traded. See assignment and exercise.
An approximation of the change in the price of an option relative to a change in the price of the underlying stock when all other factors are held constant. For example, if a call has a price of $1.5 and a delta of .33, if the underlying stock moves up $1, the option price would be $1.83 ($1.5 (.33 x $1.00)). Generated by a mathematical model, delta depends on the stock price, strike price, volatility, interest rates, dividends, and time to expiration. Delta also changes as the underlying stock fluctuates. See gamma.

An approximation of the change in the delta of an option relative to a change in the price of the underlying stock when all other factors are held constant. Gamma is accurate for small changes in the price of the underlying stock, but is expressed in terms of a change in delta for a 1 point move in the stock. For example, if a call has a delta of .49 and a gamma of .03, if the stock moves down 1 point, the call delta would be .46 (.49 (.03 x -$1.00)). Generated by a mathematical model, delta depends on the stock price, strike price, volatility, interest rates, dividends, and time to expiration.

Only in-the-money options have intrinsic value, and intrinsic value can never be zero or less. For example, if a call option with a strike price of $50 has a price of $2.75, with the stock price at $52, the intrinsic value is $2.00. If a put option with a strike price of $15 has a price of $1.50, with the stock price at $14, the intrinsic value is $1.00. Compare to extrinsic value.

For example, a long 50/60/70 iron butterfly is long 1*50 put, short 1*60 call, short 1*60 put, and long 1*70 call. It's important to understand that you buy an iron butterfly for a credit, that is, you take money in when you buy it.

The options are all on the same stock and of the same expiration, with the quantity of long options and the quantity of short options netting to zero. Generally, the strikes are equidistant from each other, but if the strikes are not equidistant, the spread is called an iron pterodactyl. An iron condor can be seen as a strangle at the middle strike and a strangle at the outer strikes. For example, a long 50/55/60/65 iron condor is long 1*50 put, short 1*55 put, short 1*60 call, and long 1*65 call. It's important to understand that you buy an iron condor for a credit, that is, you take money in when you buy it.

An acronym for Long-term Equity AnticiPation Securities. LEAPS are call or put options with expiration dates set as far as two years into the future. They function exactly like other, shorter-term exchange-traded options.
A term describing one option of a spread position. When someone "legs" into a call vertical, for example, he might do the long call trade first and does the short call trade later, hoping for a favorable price movement so the short side can be executed at a better price. Legging is a higher-risk method of establishing a spread position, and Thinkorswim STRONGLY suggests that if you decide to leg into a spread, you should, for margin and risk purposes, do the long trades FIRST.
The ability to control of a larger amount of money or assets with a smaller amount of money or assets, typically done by borrowing money or using options. If prices move favorably for a leveraged position, the profits can be larger than on an unleveraged position. However, if prices move against a leveraged position, the losses can also be larger than on an unleveraged position, but not necessarily with an options position. Buying stock on margin is using leverage. A long option position is leveraged because it "controls" a large number of shares with less money than it would take to maintain a position with the same number of shares.

A reversal is a way to exploit mispricings in carrying costs.
An action taken by a corporation in which the number of outstanding shares is reduced and the price per share increases. For example, if a trader were long 100 shares of stock of a company with a price of $80, and that company instituted a 1-for-4 reverse split, the trader would see his position become long 25 shares of stock with a price of $320.

This is typically expressed for a one-percent (100 basis point) change in interest rates. For example, if a call has a price of $4.00 and a rho of 0.2, if interest rates rise 1%, the call would have a price of $3.8 ($4.00 - (.2 x 1.00)). Generated by a mathematical model, rho depends on the stock price, strike price, volatility, interest rates, dividends, and time to expiration.

For example, short the SEP/DEC 70 roll is long 1 September 70 call, short 1 September 70 put, short 1 December 70 call, and long 1 December 70 put. The roll is usually executed when someone wishes to roll from a hedge in an expiring month to a hedge in a deferred month for added time.

Volatility skew, or just "skew", arises when the implied volatilities of options in one month on one stock are not equal across the different strike prices. For example, there is skew in XYZ April options when the 80 strike has an implied volatility of 45%, the 90 strike has an implied volatility of 47%, and the 100 strike has an implied volatility of 50%. If the implied volatilities of options in one month on one stock ARE equal across the different strike prices, the skew is said to be "flat".
