Down-and-In Option
A form of a knock-in option whose payoff is determined by the price of the underlying asset sinking to the barrier price level.
Investopedia Commentary
If the underlying asset does reach the barrier price level, the down-and-in option becomes a vanilla European call or put option. If the underlying asset price does not reach the barrier level, the option expires worthless. Investors may choose a down-and-in option rather than directly purchasing the vanilla option, as option premiums tend to be significantly lower for knock-in options.
