A practical introduction to option contract trading.

Option contract trading can feel overwhelming at first. But with clear goals and a solid foundation, the path becomes far more manageable. This primer walks you through everything you need before placing your first trade.

Defining your trading goals.

The first step in options trading is to clearly define what you’re trying to accomplish. Option contracts are a versatile instrument — they serve very different purposes depending on the portfolio and the objective. Without a clear goal, strategy selection becomes guesswork.

Ask yourself: are you trying to generate income from existing positions? Hedge a portfolio against downside? Speculate directionally with defined risk? Each objective leads to a completely different set of strategies, timeframes, and risk tolerances. Articulating your aim upfront is what makes the rest of the process coherent.

Selecting the right strategies.

With your goals in focus, the next step is identifying which option strategies are aligned with them. The universe of strategies is large, but most fall into a few categories based on what you’re trying to achieve.

If your goal is to enhance the returns from an existing position — for example, a portfolio of REITs — strategies like selling covered calls or cash-secured puts are a natural fit. If your goal is to hedge a concentrated equity position against a broad market decline, buying put options on an index that mirrors your exposure makes more sense.

The point is that strategy selection is not about finding the “best” strategy in the abstract — it’s about matching the right tool to your specific objective. For detailed breakdowns of individual strategies, see the Option Strategies page.

Choosing a brokerage.

When you’re ready to trade, brokerage selection matters more than most new traders expect. A broker is more than a platform that routes your orders — the right firm can meaningfully shape your development as a trader.

Full-service vs. discount brokers

Full-service firms provide strategic advice and can help clients integrate option trading into broader financial plans. They offer guidance on goals, strategy selection, and risk/reward tradeoffs. They typically charge higher fees in exchange for that advisory relationship.

Discount brokers offer lower transaction fees without personalized advisory services. They are well-suited for experienced traders who already have a clear strategy and simply need efficient execution.

Regardless of which type you choose, it’s worth discussing your plans with your broker before initiating or closing any position — especially early on. Most platforms also offer paper trading accounts so you can practice without putting real capital at risk.

Account approval levels.

Not every investor is approved to trade every type of option strategy. Brokerage firms evaluate your profile and assign you a specific approval level — typically ranging from Level 1 to Level 4 or 5 — which determines which strategies you can access.

This tiered system exists for good reason. Certain strategies — particularly those involving naked or uncovered options — carry theoretically unlimited risk. Firms restrict access to these strategies to protect both themselves and their clients from defaults and over-leverage.

What determines your level

• Trading experience — years of experience, number of trades, familiarity with options
• Liquid net worth — the assets available to cover potential losses
• Investment objectives — income, growth, speculation, hedging
• Knowledge of risks — firms may quiz you or require you to confirm your understanding

Higher approval levels unlock more complex strategies. Covered calls and long options are usually Level 1–2. Selling naked calls — which requires the highest approval — is only available to experienced traders with substantial liquid assets.

Administrative requirements.

Before you can trade options, your brokerage will require you to complete an option contract agreement form. This document enables the firm to assess your knowledge of options, the strategies you intend to use, and your overall investment experience.

You’ll also be required to review the SEC document Characteristics and Risks of Standardized Option Contracts. Firms are required to provide this to all prospective option traders. It covers in-depth examples of the risks linked to specific contracts and strategies and is worth reading before you place your first trade.

Account balance and margin.

Unlike stocks, option contracts cannot be purchased on margin — you must pay the full premium in cash. However, selling certain options (particularly naked or uncovered positions) requires a margin account and sufficient capital to cover the potential obligation.

Maintaining your balance

If you hold a margin account, your brokerage will require you to maintain a minimum balance. If the value of your account falls below that minimum — due to losing positions or market moves — your firm will issue a margin call. A margin call is a notice that you must deposit additional funds to bring your account back above the minimum.

If you fail to meet a margin call, the brokerage reserves the right to liquidate positions in your account without your prior consent. This is one of the most important risk management realities to understand before selling options.

What an option contract is.

An option contract is a binding agreement that provides the right — but not the obligation — to buy or sell a specific financial asset at a specified price on or before a specified date.

The asset the contract references is called the underlying. For equity options, the underlying is typically a stock or ETF. For futures options, the underlying is a futures contract. The specified price is the strike price. The specified date is the expiration date — after which the contract has no value.

Options come in two types:

• Calls — give the holder the right to buy the underlying at the strike price.
• Puts — give the holder the right to sell the underlying at the strike price.

Both calls and puts can be either bought or sold, creating four possible single-leg positions. Every strategy you’ll encounter is built from combinations of these four positions. See the Options Definitions page for detailed definitions of every term.

How trading works.

Buying options

When you buy a call, you acquire the right to purchase the underlying at the strike price on or before expiration. When you buy a put, you acquire the right to sell the underlying at the strike price on or before expiration. In both cases, you can sell the option back into the market before expiration rather than exercising it — and most traders do exactly that.

Selling (writing) options

When you sell or write an option, you take on an obligation. Selling a call obligates you to sell the underlying at the strike price if the buyer exercises the contract. Selling a put obligates you to buy the underlying at the strike price if assigned. In exchange for taking on that obligation, you collect the premium upfront.

Closing a position

A buyer can sell their contract back into the market before expiration — this is called a sell to close transaction. A writer can end their obligation by purchasing an offsetting contract before being assigned — this is called a buy to close transaction. Both actions exit the trade before expiration without exercise or assignment.

Option pricing and premiums.

The price of an option contract is called the premium. Buyers pay the premium; sellers collect it. The bid/ask spread constantly fluctuates as buyers and sellers negotiate price in real time.

Net debit vs. net credit

If you are buying options, you open the trade with a net debit — cash leaves your account. Your maximum loss is the premium paid. To be profitable, you must sell the option at a higher price than you paid, or exercise it for a gain that exceeds the premium.

If you are selling options, you open the trade with a net credit — cash enters your account. The premium is yours to keep if the option expires worthless. If the option is exercised, you are still entitled to the premium, but you must fulfill your obligation to buy or sell the underlying.

What determines the premium

Several factors influence what the market will pay for an option: the current price of the underlying relative to the strike price, time remaining until expiration, implied volatility, and interest rates. Time value and volatility are the two most significant — covered in Chapter 11.

In-the-money vs. out-of-the-money.

Whether an option is in-the-money or out-of-the-money describes the relationship between the current price of the underlying and the strike price of the contract. This relationship is one of the primary drivers of an option’s value.

An option that is not in-the-money at expiration expires worthless — the buyer loses their premium, and the seller keeps it. This is the outcome sellers are positioned for in most premium-selling strategies.

An option exactly at the strike price is referred to as at-the-money (ATM). ATM options carry the most time value and are the most sensitive to changes in implied volatility.

Time value, intrinsic value, and price factors.

An option’s premium is composed of two parts: intrinsic value and time value (also called extrinsic value).

Intrinsic value

Intrinsic value is the amount by which an option is in-the-money. An in-the-money call with a $50 strike when the underlying is trading at $55 has $5 of intrinsic value. Out-of-the-money options have zero intrinsic value — their entire premium is time value.

Time value

Time value is the portion of the premium that exceeds intrinsic value. It reflects the probability that the option will move further in-the-money before expiration — a function of how much time remains and how volatile the underlying is expected to be. Time value erodes as expiration approaches, a phenomenon called theta decay. Sellers benefit from this erosion; buyers work against it.

Factors that affect the premium

• Supply and demand — like any market, pricing reflects what buyers will pay and sellers will accept.
• Time remaining — more time means more time value. Options lose value as expiration approaches.
• Strike price — the relationship between the strike and the underlying price determines intrinsic value.
• Implied volatility — the market’s expectation of future price movement. Higher IV = more expensive options.
• Interest rates — a secondary factor; rising rates modestly increase call premiums and decrease put premiums.
