Barrier Option

Definition

A Barrier Option is a type of derivative whose payout is contingent upon whether the price of the underlying asset has reached or exceeded a predetermined threshold, known as the barrier price. They are considered exotic options, which are generally more complex than standard options. Barrier options come in two primary flavors:

Knock-In Options - These become valid and active only if the price of the underlying reaches a specified barrier.
Knock-Out Options - These lose all value or cease to exist if the price crosses the barrier.

Barrier Option vs Standard Option Comparison

Feature	Barrier Option	Standard Option
Premium	Generally cheaper	Usually more expensive
Value Determinants	Dependent on exceeding a price barrier	Value determined by the underlying asset price only
Types	Knock-In and Knock-Out	Call and Put
Complexity	More complex, path-dependent	Less complex
Activation/Expiry Value	Becomes valid (Knock-In) or invalid (Knock-Out) based on price	Valid throughout the life of the contract regardless of price movement

Exotic Options: Financial derivatives that are more complex than simple ones like puts and calls.
Path-Dependent Option: A type of option where the value depends on the path taken by the underlying asset price, rather than just its final value at expiration.
Knock-Out Option: A barrier option that becomes worthless if the underlying asset hits a certain price level.
Knock-In Option: A barrier option that only comes into play when the underlying asset surpasses a specified price.

Examples

Knock-In Example: If you have a knock-in barrier option with a barrier set at $50, this option only activates and can yield a payoff if the underlying asset, say a stock, reaches $50 or higher.
Knock-Out Example: Conversely, if you possess a knock-out option with the same barrier of $50, and the stock price hits $50, this option instantly loses its value and becomes null.
