A binary option turns a market question into a contract with two possible settlement outcomes. If the stated condition is met, it pays an agreed amount. If it is not, the buyer usually receives nothing and loses the money paid for that contract.
The question might be whether a stock index will finish above a chosen level at a stated time. Getting the general direction right is not enough: the price must satisfy the contract’s exact condition. The examples below explain the mechanics of common cash payout contracts, not recommendations to trade them.
What You Buy With a Binary Option
Buying a binary option does not mean buying the asset it references. A contract based on gold does not give you ownership of gold, and one based on a company’s shares does not make you a shareholder. You are buying a contractual payout that depends on a stated outcome.
These contracts also differ from options that give their holders a right to buy or sell an asset. Cash binary options settle automatically under their terms, without that purchase or sale right. The SEC’s explanation of binary option contracts sets out this distinction.
For a simple contract asking whether a price finishes above a threshold, the size of the winning move does not increase the final payout. Finishing slightly above the threshold can pay exactly the same amount as finishing far above it. Being almost right, meanwhile, may still mean losing the entire amount paid.
Read the Contract Before Choosing a Direction
A trading screen may reduce the decision to “Higher” or “Lower,” “Yes” or “No,” or “Call” and “Put.” Those labels do not replace the contract terms. Before considering an order, identify five things:
- The reference market: Which share, index, currency rate or other measure determines the result, and where does its settlement value come from?
- The condition and strike: The strike is the comparison level. “Above 6,000” and “at or above 6,000” are different conditions.
- The expiry: Check the date, time and time zone. Do not assume the countdown on screen tells you everything.
- The money involved: Establish the entry cost, payout for each outcome, fees and whether an advertised return includes your original stake.
- The other settlement terms: Check whether early closure is possible and how the contract handles equality at the strike, disrupted pricing or cancellation.
Also separate the price of the underlying market from the price of the option. An index level of 6,000 is not necessarily the amount you pay to enter the contract.
The order process differs between exchange traded and OTC binary options. An exchange order concerns a listed contract; an OTC contract is agreed directly with its provider. A displayed quote is not a completed trade. Check the accepted order confirmation rather than relying on the screen you saw before clicking.
A Fixed Stake Binary Option Example
Consider a hypothetical contract with these terms: you pay $100, and it pays only if an index’s settlement value is strictly above 6,000 at 4 p.m. New York time. A winning trade returns your $100 stake plus $80 profit. A losing trade returns nothing. Assume no fees, refunds or early closure.
The advertised profit rate is therefore 80%. That does not mean there is an 80% chance of winning.
| Settlement outcome | Amount returned | Profit or loss |
|---|---|---|
| Index finishes above 6,000 | $180 | $80 profit |
| Index finishes at or below 6,000 | $0 | $100 loss |
If the index settles at 6,000.1, the profit is $80. If it settles at 6,100, the profit remains $80. The contract rewards satisfying the condition, not the distance travelled beyond the strike.
Now suppose the index was at 5,990 when you entered and settles at 5,999. It rose, but the trade still loses because it did not finish above 6,000. This is why “I think the market will rise” is not a complete description of the position.
In this example, exactly 6,000 also produces a loss because the condition says strictly above. That treatment is an assumption for this example, not a universal rule. Another contract may handle equality differently.
How Exchange Contract Pricing Differs
Another structure uses a fixed settlement amount and a changing purchase price. Rather than staking $100 for an advertised percentage profit, you might buy a contract for $40 that will settle at either $100 or zero.
A fixed payout is not the same as a fixed profit. The entry price must be deducted from the amount received, a distinction illustrated by CME Group’s event contract payoff example.
Using our hypothetical $40 purchase, a favorable settlement returns $100 and produces $60 profit before fees. An unfavorable settlement returns zero and produces a $40 loss before fees. You do not receive $100 plus your $40 back: the $100 is the total settlement payment.
The same contract bought for $75 would offer only $25 potential profit against a $75 purchase cost. Bought for $20, it would offer $80 potential profit against a $20 cost. The settlement amount has not changed; the price paid has changed the balance between potential gain and loss.
These figures are dollar costs for one hypothetical contract. Real order tickets may use quoted prices and contract multipliers, so confirm the total cash amount rather than assuming a displayed number is the amount at risk.
Quantity matters too. Ten contracts bought for $40 each cost $400 before fees. A small price per contract does not make a large order small. The $100 settlement amount used here is illustrative, not a standard that applies to every exchange product.
What Happens at Expiry and Whether You Can Exit Earlier
At expiry, the contract’s settlement procedure determines whether its condition has been met. For a straightforward price threshold contract, the relevant value is compared with the strike and the applicable payout follows.
Do not assume that the last number visible on a chart is the deciding value. Read which data source and calculation the contract uses. Also distinguish the deadline for trading from the time used to determine the outcome; check both rather than treating them as interchangeable.
A hypothetical position can look favorable seconds before expiry and still finish unfavorably. If its condition concerns the final settlement value, crossing the strike earlier is not enough. Contracts based on touching a level have different conditions and should not be treated as ordinary “finish above” contracts.
The details of binary options expiry times and settlement matter most when the reference price is close to the strike. A small difference can separate the full payout from no payout.
Closing before the final outcome
Some contracts permit an exit before expiry. Where trading is available, a buyer may sell the position instead of waiting for settlement. Other contracts offer no such exit, or make it subject to the provider’s terms.
Suppose you bought the earlier hypothetical exchange contract for $40 and can later sell it for $65. Completing that sale produces $25 profit before fees. Selling for $15 instead produces a $25 loss before fees. Neither result equals the original maximum profit or maximum loss.
The two outcome structure applies to final settlement, not necessarily to every result achievable through an earlier trade. However, an exit requires an available price and successful execution. A displayed value is not a guarantee that you can close the position at that amount.
Why a Winning Percentage Can Still Lose Money
The fixed stake example risks $100 to make $80. That imbalance means winning half the trades is not enough to break even.
Across ten hypothetical trades of equal size, five wins produce $400 profit and five losses cost $500. The combined result is a $100 loss before any charges. Counting the wins alone would miss the problem.
Under those unchanged assumptions, the break even win rate is $100 divided by $180, or approximately 55.56%. Fees would raise the required rate. This calculation assumes every winner earns $80, every loser costs $100, and there are no refunds or early exits.
The wider relationship between binary options payouts and break even win rates is more useful than a headline return. A different payout changes the result even if the percentage of winning trades stays the same.
Two possible outcomes do not imply equal probabilities either. A condition that is far from being met need not have the same chance as one already close to being satisfied. The trading question is whether the price and payout justify the risk, not simply whether “up” feels more likely than “down.”
A Known Trade Loss Does Not Remove Other Risks
For the fully paid purchases illustrated here, the contractual trading loss is the amount paid, plus applicable fees. Knowing that amount is useful, but it does not make the trade safe or protect the rest of an account from repeated losses.
Five unsuccessful $100 trades cost $500. Making each decision separately does not change that total. Increasing the next stake to recover earlier losses increases the money exposed; it does not improve the contract’s payout terms.
There is also a separate question: will the platform honor the contract and return money owed? Fraud complaints involving binary options include denied withdrawals, misuse of identity information and software manipulation. These are documented in the joint CFTC and SEC alert on binary options fraud.
A balance displayed on a platform is not the same as money received in your bank account. Even a correct forecast offers little comfort if the operator refuses to pay.
Keep market risk and operator risk separate when assessing a service. The contract tells you how a legitimate trade should settle; it cannot, by itself, establish that the business is legitimate. Check the warning signs of a binary options scam before sharing identification documents or transferring funds.
Check Legal Availability Before Funding an Account
Binary options are not offered under one worldwide set of rules. Your location, the product and the entity providing it all matter.
In the United States, binary options can trade on registered exchanges, but that does not make every online offer lawful. The CFTC’s binary options investor warning distinguishes registered exchange trading from unregistered platforms. Verify the actual legal entity and relevant registration rather than accepting a badge or license number displayed on a sales page.
Check what the registration covers as well. A company name that resembles a registered business, or a claim that the operator is regulated somewhere overseas, does not answer whether the offered service is permitted for you.
In the UK, firms are prohibited from marketing, distributing or selling binary options to retail clients in or from the UK. The FCA’s retail binary options prohibition took effect on April 2, 2019. Being able to open a website or begin an application does not establish lawful access.
Before considering any contract, write down its condition, expiry, entry cost, settlement amounts and fees. Then calculate the cash result for both outcomes. If the terms leave you guessing about what constitutes a win, what constitutes a loss or who owes the payment, there is no sound basis for placing the trade.
