different type of options its terminology for beginners
⏱ 12 min read
different type of options its terminology for beginners — the quickest way to stop feeling lost when you first encounter options trading, spreads, and Greeks is to learn the main types and the words people use to describe them. This guide gives clear definitions, practical examples, and a compact roadmap so you can read option chains, compare strategies, and follow conversations with confidence.
By the end you will know what calls and puts do, how basic strategies work, and which terms matter when you assess risk and reward. The focus is clarity: short explanations, plain language, and examples you can follow on paper or in a practice account.
What are options?
Options are contracts that give the buyer the right, but not the obligation, to buy or sell an underlying asset at a set price before or at a set date. They are derivatives because their value comes from an underlying instrument such as a stock, index, commodity, or currency.
Options let traders and investors shape risk and reward more precisely than owning the underlying asset. They can be used to protect against losses, boost income, or take directional bets with limited upfront cost.
“Options compress payoff shapes into neat contracts. Learn the language first; strategy follows.” — experienced trader
Call and Put — the core types
Calls and puts are the two basic option types. A call gives its holder the right to buy the underlying at a specified price. A put gives its holder the right to sell the underlying at a specified price.
Buyers of calls expect the underlying to rise; buyers of puts expect it to fall. Sellers (writers) take the opposite view and collect the premium, accepting potential obligations if the buyer exercises the option.
- Buyer of a call: right to buy.
- Seller of a call: obligation to sell if exercised.
- Buyer of a put: right to sell.
- Seller of a put: obligation to buy if exercised.
American vs European style
Option styles define when the contract can be exercised. American-style options can be exercised any time before expiration. European-style options can only be exercised at expiration.
This difference affects pricing and strategy. American options generally command higher premiums for the added flexibility. Many equity options are American style; some index options follow European rules.
Vanilla vs Exotic options
Vanilla options are standard calls and puts with straightforward terms. They are widely traded and easy to understand. Exotic options include features that alter payoffs or triggers, such as barriers, lookbacks, or Asians (average-based payoffs).
For beginners, focus on vanilla options first. Exotic options require specialized knowledge and often suffer from lower liquidity and more complex pricing.
Strike, premium, expiration — basic terms
Strike price is the agreed price at which the underlying can be bought or sold under the option. It anchors the contract’s payoff.
Premium is the price paid to buy the option. It compensates the seller for risk and is influenced by time remaining, volatility, and the option’s moneyness. Expiration is the date when the contract ceases to exist or must be exercised.
- Strike: exercise price.
- Premium: option price paid by buyer.
- Expiration: final date to exercise.
Moneyness: ITM, ATM, OTM
Moneyness tells you how the option’s strike compares to the current price of the underlying. The main states are In The Money (ITM), At The Money (ATM), and Out of The Money (OTM).
ITM options already have intrinsic value, ATM options have a strike near the market price, and OTM options have no intrinsic value and are purely time and volatility value. Traders choose status based on cost, risk, and probability of finishing ITM.
The Greeks: delta, gamma, theta, vega, rho
The Greeks measure sensitivity to underlying factors. Delta estimates how much the option’s price changes for a small move in the underlying. Gamma measures how delta changes as the underlying moves.
Theta measures time decay — how much value the option loses each day with other factors held constant. Vega gauges sensitivity to implied volatility. Rho measures sensitivity to interest rates, which is less important for short-dated options.
- Delta: directional sensitivity.
- Gamma: convexity of delta.
- Theta: time decay.
- Vega: volatility sensitivity.
- Rho: interest-rate sensitivity.
Basic strategies for beginners
Start with single-leg positions: buying calls or buying puts. These are simple and cap your loss at the premium paid. They also show how options amplify directional bets.
Next, learn covered calls and protective puts. Covered calls involve holding the underlying while selling calls to collect income. Protective puts are bought to limit downside while keeping upside exposure.
- Long call: bullish, limited loss.
- Long put: bearish, limited loss.
- Covered call: income with partial downside protection.
- Protective put: hedge long positions.
Spreads, combos and multi-leg positions
Spreads combine buying and selling options to create defined risk and reward. Examples include vertical spreads, where you buy and sell options of the same type and expiry but different strikes.
Combinations mix calls and puts or different expiries to build more tailored payoffs. Spreads are popular because they control cost and risk compared to naked positions.
- Vertical spread: same expiry, different strikes.
- Horizontal/calendar spread: same strike, different expiries.
- Diagonal spread: different strikes and expiries.
Exercise, assignment and settlement
Exercise is when an option holder chooses to use the right to buy or sell the underlying. Assignment happens to the seller: they must fulfill the contract if the buyer exercises.
Settlement can be physical (delivering the underlying) or cash-settled (paying the difference). Know the rules for the specific market and contract style, as they affect repair strategies and risk at expiration.
Risk management and position sizing
Options can magnify returns and losses. Use position sizing to limit how much of your capital is exposed to any single trade. Define loss limits before entering a position, whether you are buying or selling.
Have clear exit rules: stop-loss, profit targets, or time-based exits. Consider scenario analysis: how the position behaves if the underlying moves a lot, volatility spikes, or time decays rapidly.
- Limit exposure per trade relative to capital.
- Use hedges when necessary.
- Review worst-case scenarios and margin obligations.
How to read an option chain
An option chain lists available strikes, their premiums, volume, open interest, and implied volatility. Read left-to-right: strikes, call side, put side, and expirations grouped by date.
Look at volume and open interest for liquidity. High open interest often means easier entry and exit. Implied volatility shows the market’s expected movement; higher values raise premiums and favor sellers if volatility normalizes downward.
Tax, account types, and margin basics
Tax rules and account permissions vary by jurisdiction and provider. Some accounts allow only buys of options until approval for more advanced strategies is granted. Understand the margin requirements and what triggers a margin call.
Use cash accounts for simpler, limited-risk trades. Margin accounts enable writing uncovered options and more complex multi-leg trades, but they increase obligation and potential loss.
Common beginner mistakes and how to avoid them
One common mistake is underestimating time decay. Buying options with very short time to expiration can erode value quickly even if the underlying moves in the expected direction.
Another mistake is ignoring liquidity. Wide bid-ask spreads increase execution cost and can make profitable-seeming trades lose money. Always check spreads, volume, and open interest before acting.
- Avoid buying options solely on rumor or emotion.
- Prefer liquid strikes and expiries for easier fills.
- Use position sizing and stop rules to manage risk.
Next steps and practice checklist
Practice by paper-trading the basic positions listed here. Track results to learn how premium, time, and volatility influence outcomes. Use small, deliberate experiments to build skill without large losses.
Build a to-do list for learning and practice. Repeat trades until you can explain why each profit or loss occurred in plain language.
- Open a practice account and find an option chain.
- Place a long call and a long put on paper with different expiries.
- Track Greeks and chart outcomes after key moves.
- Try a covered call and a protective put on paper.
- Review trades weekly and refine plan.
Practical example: a simple long call
Suppose the underlying trades near a level you expect to rise. Buying a call gives upside with limited loss. Your maximum loss equals the premium. If the underlying rises above the strike plus premium, you profit.
Record entry price, strike, premium, expiry, and your plan for exit. Simulate outcomes at several price points to understand break-even and profit potential.
Practical example: a protective put
If you own the underlying and want downside protection, buying a put limits losses below the strike while preserving upside. This is insurance: you pay a premium but gain certainty about worst-case loss.
Compare the cost of the put to other alternatives like selling covered calls, and choose the tool that matches your objective.
Frequently asked questions
What is the simplest option trade for beginners?
Buying a call or buying a put is the simplest. Risk is limited to the premium, and the position demonstrates core option behavior.
How does implied volatility affect option prices?
Higher implied volatility increases option premiums because it raises the probability of large moves. When implied volatility falls after you buy an option, its price can drop even if the underlying is unchanged.
When should I use covered calls vs protective puts?
Use covered calls to generate income when you expect modest or sideways moves. Use protective puts when you want to keep upside potential but limit downside risks during uncertain periods.
Can options expire worthless?
Yes. Options that finish out of the money at expiration expire worthless, and the buyer loses the premium while the seller keeps it.
What is open interest and why does it matter?
Open interest is the number of active option contracts outstanding at a strike and expiry. It signals liquidity and market participant interest. Higher open interest usually means easier execution.
