Binary Options Expiry, Strike, Tie, and Settlement Rules

Compare the evidence needed to verify expiry timing, strike or barrier equality, price references, and cash settlement across contract families.

Contract comparison

Evidence needed to reconstruct a settlement

The product name alone does not establish the accepted strike, observation window, equality rule, price source, or cash return.

Expiry, equality, and settlement evidence by contract family
Contract and citation	Condition	Expiry evidence	Equality question	Settlement evidence
`CS-001`Up / Down	Final reference price is compared with the accepted entry reference or strike in the selected direction.	Accepted timestamp, exact expiry timestamp and timezone	What happens when final price equals the entry reference or strike?	Accepted reference, final reference, result, cash return, price source, correction rule
`CS-002`Touch / No Touch	The result depends on whether the stated barrier is reached during the contract's observation window.	Observation start, exact end, barrier level and timezone	Does a quote exactly equal to the barrier count as touch, and which quote or tick is authoritative?	Barrier, authoritative tick or path record, observation bounds, result, cash return, correction rule
`CS-003`In / Out at expiry	Final reference price is evaluated against lower and upper boundaries at the settlement moment.	Exact expiry, both boundaries, direction and timezone	Is a final price exactly on either boundary inside, outside, a tie, or void?	Both boundaries, final reference, result, cash return, price source, correction rule
`CS-004`In / Out stay	The result depends on whether the authoritative price path stays inside or moves outside the stated range during the observation window.	Observation start and end, both boundaries and timezone	Does touching either boundary count as leaving the range, and is a single authoritative tick sufficient?	Both boundaries, authoritative path or event record, result, cash return, correction rule
`CS-005`Selectable-strike digital option	Final reference price is compared with a selected strike; displayed payout can change with strike distance and direction.	Accepted strike, payout, exact expiry and timezone	What result applies when final price equals the selected strike?	Accepted strike and payout, final reference, result, cash return, price source, correction rule
`CS-006`Clock-expiry versus timer-expiry control	This is an order-control comparison rather than a distinct payoff: Clock selects an exact settlement time; Timer selects a duration whose accepted start determines the end.	Submission, acceptance, countdown or clock value, computed and displayed expiry, timezone	The underlying contract's equality rule still applies and must be checked separately.	Event sequence from submission through acceptance, expiry, result and cash return

Publication boundary

Unknown rules remain unknown

If equality, boundary contact, observation timing, price source, correction, or refund treatment is not documented, publish not verified rather than inferring a rule.
