How Knock-in option differs from related terms

Knock-in option is often researched beside Knock-out option and Double no-touch option and No-touch option. The labels can appear in the same workflow, but they do not describe the same field or condition.

01
Knock-out option

An option that terminates or loses effect when a specified barrier is reached.

02
Double no-touch option

A fixed payout is made only if neither the upper nor lower barrier is reached during the observation period.

03
No-touch option

A barrier-style contract that pays only when price does not reach the stated target during the contract period.

Practical use

Describe the event that determines the payoff

Knock-in option means an option that becomes effective only after a specified barrier is reached. A contract label is shorthand for an outcome condition, observation rule, expiry, and predefined payoff. Marketing names vary, so the written specification matters more than the label.
