Every binary options contract settles in one of three possible states at expiry: in the money, out of the money, or at the money. In the money means your directional forecast was correct and your account is credited the payout. Out of the money means your forecast was incorrect and your stake is forfeited. At the money -- where the settlement price exactly equals the strike price -- is the edge case that most traders encounter eventually and that most platform terms handle differently. Understanding all three states before you trade is foundational to calculating your actual expected outcome from any position.
TL;DR -- Key Takeaways
- In-the-money (ITM): expiry price is above strike (for a Call) or below strike (for a Put) -- you receive your stake plus the fixed payout.
- Out-of-the-money (OTM): expiry price is below strike (Call) or above strike (Put) -- you lose your entire stake.
- At-the-money (ATM): expiry price equals the strike exactly -- broker-dependent outcome, most commonly treated as a full loss.
- The labels ITM and OTM in binary options describe settlement outcomes only -- they do not carry the same meaning as in vanilla options pricing theory.
- Your break-even win rate is determined by the payout percentage offered, not by how far in the money your winning trades finish.
1. What "In the Money" Means for a Binary Option
A binary option is in the money at expiry when the underlying asset's price has moved in the direction you predicted, relative to the strike price established at trade entry.
For a Call (Up/Higher) position: the contract is in the money when the settlement price at expiry is strictly above the strike price. The magnitude of the move does not matter -- whether price is one tick above or one hundred ticks above the strike, the payout is identical.
For a Put (Down/Lower) position: the contract is in the money when the settlement price at expiry is strictly below the strike price. Again, magnitude is irrelevant.
The ITM Payout
When a binary option settles in the money, the platform credits your account:
- Your original stake (returned in full)
- Plus the fixed payout percentage of your stake
Example: A $100 Call at 85% payout settles ITM. You receive $100 + ($100 x 0.85) = $185. Your net profit on the trade is $85.
This payout is determined at trade entry -- it does not change based on how far in the money the contract finishes. A contract finishing $0.0001 above the strike pays exactly the same as one finishing $100 above the strike.
2. What "Out of the Money" Means for a Binary Option
A binary option is out of the money at expiry when the underlying asset's price has moved against the direction you predicted.
For a Call position: OTM when settlement price is strictly below the strike.
For a Put position: OTM when settlement price is strictly above the strike.
The OTM Outcome
When a binary option settles out of the money, your entire stake is forfeited. You receive $0 back on that trade.
Example: A $100 Call settles OTM (price at expiry is below the strike). You lose the full $100 stake.
This is the maximum loss per trade in binary options. Unlike leveraged CFDs, there are no additional losses beyond the stake -- but the full stake loss is certain, not partial.
The Asymmetry This Creates
Because you win less than 100% on a correct prediction (the payout is, for example, 80%) but lose 100% on an incorrect prediction, the expected value of each trade is negative unless your win rate is above the break-even threshold:
Break-even win rate = 1 / (1 + payout rate)
At 80% payout: 1 / 1.80 = 55.6%
This means you must win more than 55.6% of your trades at an 80% payout simply to avoid losing money over time. This is a mathematical derivation from expected value, not an empirical statistic.
3. What "At the Money" Means -- and Why It Is Rarely Discussed
At the money describes the edge case where the settlement price at expiry exactly equals the strike price established at trade entry.
This is statistically rare in live trading -- price is a continuous stream of decimal values and exact strike matches at the precise expiry second are uncommon. But they do occur, particularly on platforms with price feeds rounded to fewer decimal places, or during low-volatility conditions where price barely moves from entry to expiry.
How Different Platforms Handle ATM Settlement
Platform terms differ significantly on this edge case:
| ATM Treatment | Description | Most Common? |
|---|---|---|
| Full loss | Stake forfeited as if OTM | Yes -- the majority of retail platforms |
| Stake return | Original stake returned, no profit | Some platforms (often called "push") |
| Partial payout | A percentage (e.g., 15%) paid as a consolation | Rare |
Before trading on any platform, check its terms of service or FAQ under "at the money," "tie," or "push" to know which rule applies. This matters most during calm markets where small-range assets can settle very close to the strike.
4. How ITM and OTM Differ from Vanilla Options Terminology
Traders familiar with vanilla (standard) options markets may recognize the terms in-the-money, out-of-the-money, and at-the-money from that context -- but the meaning differs in an important practical way.
In vanilla options pricing theory:
- ITM describes an option that has intrinsic value (the current market price is already favorable relative to the strike), which affects the option's premium.
- OTM describes an option with no intrinsic value, priced only on time value and implied volatility.
- ATM describes an option where the strike equals the current market price.
These labels in vanilla options affect the option's price before expiry. In binary options, the labels have no effect on the trade cost or payout structure before expiry -- they only describe the settlement state at the expiry moment. A binary option has no time value to decay and no intrinsic value in the pricing sense. Its cost is fixed (your stake) and its payout is fixed (the payout percentage) regardless of where current price sits relative to the strike during the contract's life.
Conflating the two systems leads to confusion. In binary options, ITM/OTM/ATM are post-settlement descriptors only.
5. Practical Implications for Payout Math
Understanding settlement states allows you to model the expected return of a trading approach before executing it.
Single trade expected value:
EV = (Win rate x Net profit) - (Loss rate x Stake) EV = (W x Stake x Payout rate) - ((1 - W) x Stake)
At W = 0.56 (56% win rate), Payout rate = 0.80, Stake = $100:
EV = (0.56 x $100 x 0.80) - (0.44 x $100) EV = $44.80 - $44.00 EV = +$0.80 per trade
At W = 0.54 (54% win rate), same payout:
EV = (0.54 x $80) - (0.46 x $100) EV = $43.20 - $46.00 EV = -$2.80 per trade
The difference between a profitable approach and an unprofitable one at 80% payout is roughly 2 percentage points of win rate (54% loses money; 56% generates a small edge). This is why claiming a strategy "works" based on a small number of trades is statistically unreliable -- the difference between edge and no-edge is tiny and requires a large sample to confirm.
6. How Settlement State Affects Your Trading Records
Tracking settlement states -- not just outcomes -- in your trading log provides additional diagnostic information.
Recording by settlement state (not just win/loss):
| Date | Asset | Direction | Expiry | Settlement State | Payout | Net P&L |
|---|---|---|---|---|---|---|
| 2026-09-29 | EUR/USD | Call | 15 min | ITM | 82% | +$82 |
| 2026-09-29 | EUR/USD | Put | 15 min | OTM | 82% | -$100 |
| 2026-09-29 | GBP/USD | Call | 5 min | ATM | 82% | -$100 (platform rule: full loss) |
Tracking ATM outcomes separately tells you whether the platform's ATM rule is affecting your results -- if you are trading in low-volatility conditions or on assets where price often stalls at round numbers (key psychological levels), ATM settlements may be more frequent than average.
Frequently Asked Questions
Does how far in the money a binary option finishes affect the payout?
No. The distance by which the settlement price exceeds the strike has no effect on the payout. A Call that finishes 0.0001 above the strike pays the same as one that finishes 50 points above. This is the fundamental difference from vanilla options and CFDs, where profit scales with price movement.
What is the most common platform rule for at-the-money settlement?
Most retail binary options platforms treat at-the-money as a full loss -- your stake is forfeited, same as an out-of-the-money result. A smaller number of platforms return the stake without profit (a push). Check your specific broker's terms before encountering this scenario live.
Can you tell if a trade is in the money before expiry?
The platform may show a live "in the money / out of the money" indicator during the contract's lifespan, reflecting the current price relative to the strike. This is informational only -- what matters is the price at the exact expiry second, not the state at any point during the contract. A trade that is in the money 59 seconds into a 60-second contract can still settle out of the money if price reverses in the final second.
Why do some platforms offer higher payouts for out-of-the-money selections?
Some platforms, particularly those offering exotic contract structures, allow you to select a strike price that is different from the current market price -- placing it further out of the money or in the money. A strike set further OTM is harder to reach (lower probability of success) so the platform may offer a higher payout to compensate. A strike set further ITM (already past the current price in your favor) offers a lower payout because it is more likely to settle in the money. This creates a risk-reward tradeoff analogous to option moneyness in vanilla markets.
Does a binary option's in-the-money status during the contract affect the early-close price?
Yes. If the platform offers an early-close (sell-back) feature, the price at which you can close the contract early is influenced by the contract's current in-the-money or out-of-the-money status relative to the current market price and the time remaining. A deeply in-the-money contract near expiry commands a higher early-close value than one barely in the money with significant time remaining.
How do I calculate my expected outcome if I know my win rate and the payout percentage?
Use the expected value formula: EV = (Win rate x Payout rate) - (1 - Win rate). Multiply EV by your stake to get the expected dollar result per trade. For example, at a 57% win rate and 80% payout: EV = (0.57 x 0.80) - 0.43 = 0.456 - 0.43 = +0.026, or $2.60 expected profit per $100 trade. This is a mathematical derivation from the payout structure, not an empirical prediction of any specific trade's outcome.
7. How Payout Percentages Interact with Settlement States
A useful cross-reference: the break-even analysis for binary options settlement outcomes changes depending on the payout offered.
Higher payout percentages reduce the win-rate hurdle but do not change the settlement mechanics. A contract that settles in the money at 90% payout returns more per win than one at 75% payout -- but both still forfeit 100% of the stake on an out-of-the-money result. The settlement states themselves are neutral; the payout percentage determines the mathematical consequences of those states.
When comparing two platforms, evaluating their payout rates is more meaningful than comparing visual interface features -- because payout directly determines the break-even win rate you must sustain to remain profitable.
