Options Trading Terminology: A Glossary for Beginners
Options trading comes with its own language, and understanding this terminology is crucial for successful trading. Whether you're reading research reports, watching financial news, or discussing strategies with other traders, fluency in options vocabulary separates beginners from informed traders.
Basic Options Terms
Assignment
When a short option is exercised against you, forcing you to fulfill the contract obligations. If you sold Tesla $200 calls and they're exercised, you must sell 100 shares at $200 per contract.
At-the-Money (ATM)
An option whose strike price equals the current stock price. If Apple trades at $175, the $175 calls and puts are at-the-money.
Bid-Ask Spread
The difference between the highest buying price (bid) and lowest selling price (ask). A Tesla option with $5.20 bid and $5.40 ask has a $0.20 spread.
Call Option
A contract giving the buyer the right to purchase stock at a specific price before expiration. Bullish traders buy calls to profit from rising prices.
Cash-Settled
Options that settle in cash rather than stock delivery. Index options like SPX settle in cash based on the index value at expiration.
Covered Call
Selling call options against stock you own. If you own 100 shares of Meta and sell one $300 call, you're "covered" by your stock position.
Delta
A Greek measuring how much an option's price changes per $1 move in the underlying stock. A 0.50 delta means the option moves $0.50 for every $1 stock move.
Exercise
Converting an option into stock by using your right to buy (calls) or sell (puts) at the strike price.
Expiration Date
The last day an option can be exercised. Most equity options expire on the third Friday of each month.
Gamma
A Greek measuring how quickly delta changes as the stock price moves. High gamma options have rapidly changing deltas.
Implied Volatility (IV)
The market's expectation of future price movement embedded in option prices. High IV means expensive options; low IV means cheaper options.
In-the-Money (ITM)
Options with intrinsic value. For calls, strike price below stock price. For puts, strike price above stock price.
Intermediate Terms
Iron Condor
A four-legged strategy combining put and call spreads, profiting from low volatility and time decay. Popular for sideways markets.
LEAPS (Long-term Equity Anticipation Securities)
Options with more than one year to expiration, typically expiring in January. Used for long-term strategies.
Liquidity
How easily you can buy or sell an option. High liquidity means tight bid-ask spreads and good volume.
Naked Option
Selling options without owning the underlying stock (calls) or having cash coverage (puts). Higher risk strategy.
Open Interest
Total number of outstanding option contracts. High open interest usually indicates good liquidity.
Out-of-the-Money (OTM)
Options with no intrinsic value. For calls, strike price above stock price. For puts, strike price below stock price.
Pin Risk
When a stock closes very close to a strike price at expiration, creating uncertainty about exercise.
Put Option
A contract giving the buyer the right to sell stock at a specific price before expiration. Bearish traders buy puts to profit from falling prices.
Roll
Closing an existing option position and opening a new one with different strike or expiration. Often used to extend losing trades.
Strike Price
The price at which an option can be exercised. A Tesla $200 call gives you the right to buy Tesla at $200.
Theta
A Greek measuring time decay – how much an option loses value each day due to approaching expiration.
Vega
A Greek measuring sensitivity to volatility changes. High vega options are more affected by volatility shifts.
Advanced Strategy Terms
Butterfly Spread
A strategy using three different strikes with the same expiration, creating a position that profits from minimal price movement.
Calendar Spread
Buying and selling options with the same strike but different expiration dates, profiting from time decay differences.
Collar
Owning stock while simultaneously buying protective puts and selling covered calls. Limits both upside and downside.
Credit Spread
A strategy where you receive more premium for options sold than paid for options bought. Bull put spreads and bear call spreads are examples.
Debit Spread
A strategy where you pay more for options bought than received for options sold. Bull call spreads and bear put spreads are examples.
Diagonal Spread
Combining different strikes and expiration dates, typically buying longer-term options and selling shorter-term options.
Ratio Spread
Using unequal numbers of contracts at different strikes. Might buy one ATM call and sell two OTM calls.
Straddle
Buying both calls and puts with the same strike and expiration, profiting from large moves in either direction.
Strangle
Buying calls and puts with different strikes but same expiration, similar to straddle but with lower cost and higher breakeven points.
Market Condition Terms
Backwardation
When near-term options are more expensive than longer-term options, unusual but occurs during high volatility periods.
Contango
Normal market condition where longer-term options cost more than shorter-term options due to additional time value.
Volatility Crush
Sharp drop in implied volatility, typically after earnings announcements, causing option values to decline regardless of stock movement.
Volatility Skew
Different implied volatilities across strikes, typically with OTM puts having higher IV than ATM options.
Volatility Smile
IV pattern where both far OTM calls and puts have higher IV than ATM options, creating a "smile" shape.
Order Types and Execution Terms
All-or-None (AON)
Order that must be filled completely or not at all. Used to avoid partial fills on small orders.
Fill-or-Kill (FOK)
Order that must be executed immediately in its entirety or canceled.
Good-Till-Canceled (GTC)
Order that remains active until filled or manually canceled, typically lasting 60-90 days.
Limit Order
Order specifying the maximum price you'll pay (buy) or minimum price you'll accept (sell).
Market Order
Order to buy or sell immediately at the best available price. Risky with options due to wide spreads.
Stop-Loss Order
Order that becomes a market order when the option reaches a specified price, used to limit losses.
Risk Management Terms
Maximum Loss
The most you can lose on a position. For option buyers, it's the premium paid. For spreads, it's the difference between strikes minus credit received.
Maximum Profit
The most you can make on a position. Varies by strategy but important for calculating risk-reward ratios.
Probability of Profit (POP)
Estimated likelihood that a position will be profitable at expiration, based on current market pricing.
Risk-Reward Ratio
Comparison of potential loss to potential gain. A position risking $100 to make $200 has a 1:2 risk-reward ratio.
Common Options Slang
"Going Long"
Buying options or stock. "I'm going long Tesla calls" means buying Tesla call options.
"Going Short"
Selling options or stock. "I'm short Apple puts" means selling Apple put options.
"Theta Gang"
Traders who primarily sell options to collect time decay, betting that most options expire worthless.
"Diamond Hands"
Holding positions despite volatility or temporary losses, popularized in retail trading communities.
"Paper Hands"
Selling positions quickly at the first sign of trouble, opposite of diamond hands.
"YOLO"
"You Only Live Once" – making large, risky trades. Generally not recommended for consistent success.
"Bag Holder"
Someone stuck holding losing positions, hoping for recovery.
"Moon"/"Mooning"
Dramatic price increases. "Tesla is mooning" means Tesla is rising rapidly.
Platform-Specific Terms

Greeks Display
Platform feature showing delta, gamma, theta, and vega for each option.

Simulated trading with fake money to practice strategies without financial risk.

Understanding Context
Research Reports
When analysts mention "elevated IV" or "rich premiums," they mean options are expensive relative to historical norms.
News Coverage
Financial media often uses terms like "call buying" or "put volume" to describe market sentiment.
Social Media
Trading communities use slang heavily. Understanding terms like "FDs" (weekly options) or "tendies" (profits) helps decode discussions.
Broker Communications
Account statements and trade confirmations use formal terminology. Understanding these terms helps track performance accurately.
