Common comparison error
Time to expiry is the remaining contractual duration from the defined accepted point; it is not the chart interval or necessarily the time since button press.
GlossaryPricing & settlement
Time to expiry
The remaining duration between contract acceptance and final evaluation. It provides a common way to compare countdown and exact-clock expiry controls.
Practical use
How to verify Time to expiry
Read Time to expiry together with Clock expiry, Expiry cutoff, End-of-day expiry. The comparison must preserve the exact rule, value, state, and evidence described below.
A neutral example
A user clicks at 14:00:00.100, the server accepts at 14:00:00.380, and evaluation occurs at 14:01:00.380. The accepted time to expiry is 60 seconds even though click-to-expiry is longer.
Evidence path
Where to verify Time to expiry
Use the source that governs the exact contract, account, entity, or platform state. A general definition cannot replace current broker terms.
