🎯 In 30 seconds: You cannot trade options just by opening a brokerage account. FINRA Rule 2360 requires your broker to collect facts about your finances and experience, have a qualified principal approve the account, and give you the Options Disclosure Document, "Characteristics and Risks of Standardized Options", at or before approval. Most brokers sort customers into approval levels, from basic strategies up to uncovered selling. Start with trades whose worst case you know in dollars, and keep that worst case small.
Why options need permission
Buying a share of stock can cost you, at most, what you paid. Options can behave very differently. A bought option can go to zero in days. An uncovered sold call can lose many times the premium received, with no upper limit. Because of that, regulators treat options accounts as a separate step with its own rules.
The main rule for brokers is FINRA Rule 2360, which covers options. FINRA is the self-regulatory organization that oversees US broker-dealers, under the SEC. See Who runs and polices the market.
What FINRA Rule 2360 requires
The account approval part of the rule, paragraph (b)(16), says in summary:
- Due diligence. The firm must exercise due diligence to learn the essential facts about you before approving options trading.
- Information collected. For individuals, the firm should seek at least: investment objectives, employment status, estimated income, net worth (excluding your home), liquid net worth, marital status and dependents, age, and your investment experience with options and other securities. If you refuse to give something, that refusal is noted.
- Approval in writing. A qualified supervisor, such as a Registered Options Principal, must approve or reject the account in writing, and the record shows which kinds of options transactions you are approved for.
- Verification. Within 15 days of approval, the firm sends you the background and financial information it relied on so you can correct it.
- Agreement. Within 15 days of approval, you sign an agreement to follow the rules, including position and exercise limits.
Paragraph (b)(11) adds that the firm must deliver the current Options Disclosure Document to you at or before the time your account is approved for options. For uncovered option writing, firms must also have written procedures, minimum equity requirements, and a special written risk statement delivered before your first uncovered short option trade.
Approval levels
The rule does not define levels. Firms do. In Regulatory Notice 22-08 (March 2022), FINRA described how many firms have built systems of options "levels", from less risky to more risky strategies, based on the customer's risk tolerance, experience and whether they have a margin account, with processes for moving up.
Levels differ from firm to firm, so treat this as an example of a common pattern, not a standard:
| Example level | Typical strategies | Worst case |
|---|---|---|
| Lowest | covered calls, sometimes protective puts and cash-secured puts | roughly the risk of owning the stock |
| Next | buying calls and puts | premium paid |
| Middle | spreads with a long and a short option, such as vertical spreads | defined, often the width of the spread minus the credit |
| Highest | uncovered (naked) calls and puts, sometimes uncovered index options | very large, unlimited for naked calls |
Spreads and uncovered positions usually need a margin account. Read your own broker's level definitions before you apply. Some firms offer only the lower levels and never allow uncovered positions.
The Options Disclosure Document
The Options Disclosure Document (ODD) is a booklet titled Characteristics and Risks of Standardized Options. It is published by the Options Clearing Corporation (OCC), the clearinghouse for US-listed options, and it explains how standardized options work and the main risks of trading them. Every broker must give it to you before you trade, and send you amendments when it changes.
It is long and dry, and most people never read it. Read at least the sections on risks of buying and writing options and on exercise and settlement. Many of the surprises beginners run into, such as automatic exercise, early assignment and index cash settlement, are described there in plain terms. FINRA has noted that many firms rely only on delivering the ODD to inform customers, so do not count on anyone explaining it for you.
The risks, listed honestly
- Total loss, fast. A bought option can expire worthless. Short-dated options can lose most of their value in days or hours. See What an option is worth.
- Leverage. A small stock move becomes a large percentage move in the option, in both directions.
- Time decay. Buyers pay for every day that passes without a move.
- Volatility. An IV drop can make you lose money even when you are right on direction. See Implied volatility.
- Costs and liquidity. Wide bid-ask spreads can take several percent per trade. See Reading an options chain.
- Assignment. Sellers of American-style options can be assigned any business day and end up with shares, or a short stock position, they did not plan for. See Exercise and assignment.
- Unlimited or very large losses for sellers. An uncovered call has no maximum loss. An uncovered put can lose nearly the whole strike value.
- Gaps. Stocks can open far from the prior close after news. Stop orders on options do not protect you from a gap.
- Margin calls. Short options need margin. A move against you can raise the requirement and force a sale at a bad price. See Margin.
- Same-day options. FINRA warns that 0DTE options are very sensitive to the underlying price, that buyers can lose the whole premium in one day, and that a firm may close a position before the close if you lack the funds to meet the obligation.
The evidence on outcomes is sobering. A study published in the Review of Finance in 2025 found that retail investors buying options before earnings announcements lost 5% to 9% on average, and 10% to 14% around the most volatile announcements, from overpaying for volatility, wide spreads and slow reactions.
Defined risk vs undefined risk
A position has defined risk when its maximum loss is known when you open it. Buying a call, buying a put and spreads with a long option protecting a short one are defined risk. A position has undefined risk when the loss has no fixed limit, like an uncovered call.
"Defined" does not mean "small". A cash-secured put has a defined worst case, but on a $48 strike that worst case is $4,660 per contract. Always turn the definition into a dollar number.
Here is the same bearish-to-neutral idea expressed two ways, using the hypothetical prices from Call options: the $50 call at $2.60 and the $55 call at $0.85.
- Uncovered call: sell the $50 call, collect $260. Breakeven $52.60. No maximum loss.
- Call spread: sell the $50 call and buy the $55 call. Net credit $2.60 - $0.85 = $1.75, or $175. Breakeven $50 + $1.75 = $51.75. Maximum loss (width $5 - credit $1.75) x 100 = $325.
You give up $85 of income to cap the loss. If Company X jumps to $70 on a takeover bid, that $85 is the difference between losing $325 and losing $1,740. Spreads are covered fully in Vertical spreads.
Why beginners should start with defined risk
- You can size it. If the worst case is $175, you can decide in advance whether $175 is an acceptable loss for your account. With an undefined loss, you cannot.
- Mistakes are survivable. Your first options mistakes will probably be misreading the chain, the multiplier or the expiration. A defined-risk trade limits the damage.
- No surprise margin calls from a single gap. Long options and fully paid spreads do not grow their loss beyond what you can see.
A practical sizing rule: keep the maximum loss of any one options trade to 1% or 2% of your account. On a $5,000 account, that is $50 to $100, which may mean one small spread or nothing at all. That is fine. See Risk comes first and Managing options risk.
Try it
Find your broker's options agreement and level descriptions, and the copy of the ODD it provides. Read the ODD's section on the risks of buying and writing options. Then, before applying for any level, place ten hypothetical defined-risk trades on paper using real option chains, track them in your trading journal to expiration, and record the result, the spread you would have paid and any assignment that would have happened. You can practice the stock side in the paper portfolio. If the ten trades lost money in total, find out why before trading with real money.
