Binary options trading has its own language. ITM, OTM, expiry, payout — if you’re new, it sounds like alphabet soup. But here’s the thing: each term maps to a real trading decision. Misunderstand “expiry,” and you pick the wrong trade. Misunderstand “payout,” and you don’t know your risk. Let’s fix that.
Trading involves risk. Binary options trading involves substantial risk of losing your capital. This glossary is for educational purposes only. Never trade money you cannot afford to lose.
How to Use This Glossary
Each term includes a plain-English definition, a real trading example, and a link to a detailed guide. Terms are grouped by category — trade mechanics first, then platform features.
Binary Options Terms
Call / Put
The two trade directions in binary options. A Call means you predict the price will be HIGHER at expiry than the current price. A Put means you predict it will be LOWER. Everything in binary options comes down to this simple choice — up or down? No limit orders, no stop-losses, just direction + time (binary options vs forex: how direction trading differs →).
Example: EUR/USD is at 1.0850. You think it will rise in the next 5 minutes. You buy a CALL at 1.0850 with 5-minute expiry. If EUR/USD is above 1.0850 at expiry, you win the payout. If below, you lose the trade amount.
ITM (In The Money)
Your trade finishes “in the money” when price closes on the side you predicted — above the strike for a Call, below for a Put. If you buy a Call at 1.0850 and the price is 1.0860 at expiry, your trade is ITM and you earn the payout percentage (learn a strategy with clear ITM entries →).
Common confusion: Many beginners think ITM means “profitable” in the sense of earning life-changing money. A $10 ITM trade with 85% payout returns $8.50 profit — not $18.50. ITM simply means your prediction was correct.
OTM (Out of The Money)
The opposite of ITM. Your trade finishes OTM when price closes against your prediction — below the strike for a Call, above for a Put. When OTM, you lose the amount you risked on that trade. OTM losses are fixed: you never lose more than what you put in, which is a key difference from forex trading (learn what makes binary options different →).
Example: You place a $10 CALL on gold at $2,350. Gold closes at $2,348 at expiry — 0.08% below your entry. Your trade is OTM. You lose your $10, regardless of how close the price was.
Expiry
The precise time when a binary options trade settles and the outcome is determined. Expiry times range from 60 seconds (turbo options) to 1 hour or more. The expiry you choose must match your trading timeframe and strategy. A strategy that works on 15-minute charts needs at least 5-15 minute expiries — not 60-second turbo options (see how expiry timing works with RSI divergence →).
Example: You spot a signal on the 5-minute chart. Typical rule: expiry should be 2-3× the chart timeframe. For a 5-minute signal, use 10-15 minute expiry. For a 1-minute signal, use 3-5 minute expiry.
Payout
The percentage return on a winning trade. If a platform offers 85% payout and you place a $10 trade: a win returns $8.50 profit (your $10 + $8.50 = $18.50 total). A loss costs the full $10. This means you need a win rate higher than 54% to break even with 85% payout (the breakeven formula: 100 ÷ (100 + payout percentage)). Higher payout = lower required win rate (compare payouts across platforms →).
Example: Platform A offers 80% payout, Platform B offers 95%. On Platform A, you need 55.6% win rate to break even. On Platform B, you need 51.3%. That 15% difference is huge over 100 trades.
Strike Price
The price at which you enter the trade. In binary options, the strike price is the market price at the moment you open the trade (for standard trades) or a price you select (for some advanced platforms). The trade is “in the money” if the market price at expiry is on the correct side of the strike price.
Turbo Option
A binary option with a very short expiry — typically 60 seconds to 5 minutes. Turbo options are high-speed, high-risk trades. They’re popular among experienced traders but dangerous for beginners. The shorter the expiry, the more random the outcome: a 60-second trade has more luck factor than a 15-minute trade (learn a strategy better suited for standard expiries →).
Example: 60-second turbo options on the 1-minute chart. You’re betting on a micro-move. A news blip, a large order, or a spread widening can flip the outcome — even with a correct directional read.
Digital Option
A standard binary option with fixed expiry, fixed payout, and fixed risk. “Digital” means the outcome is binary — you get the payout or you don’t, there’s no gradation. This is the default binary option type on most platforms. Some platforms also offer “one-touch” options (pays out if price touches a level before expiry) and “range” options (pays out if price stays within a range).

Common Confusions
ITM vs “Profit” — Many beginners think ITM means they doubled their money. A $10 ITM trade with 85% payout = $8.50 profit, not $10 profit. ITM simply means your prediction was correct.
Turbo vs Standard — Both are binary options, but turbo has shorter expiry (60 sec to 5 min), higher randomness, and smaller profit potential per trade relative to risk. Standard options (5 min+) give the market more time to move in your favor if your directional read is correct.
