Common comparison error
A knock-in barrier activates the option; reaching it is not necessarily the final winning condition or immediate cash payment.

Practical use
How to verify Knock-in option
Read Knock-in option together with Knock-out option, Double no-touch option, Double one-touch option. The comparison must preserve the exact rule, value, state, and evidence described below.
A neutral example
A knock-in option starts inactive and becomes operative only when the named source reaches 105 during the observation window. If the barrier never triggers, the later favorable final price does not activate the payoff.
Evidence path
Where to verify Knock-in option
