A Binary Barrier Option is a type of digital option for which an option's payout depends on whether or not the asset touched a barrier level at binary and barrier options time during the life of the option.

The value of the payoff is not affected by the size of the difference between the underlying and the strike price, and can be in the form of a cash payment or delivery of the underlying. The options described here are path dependent, which means that the payout profile depends on the asset value during the life of the option and the value of the underlying asset when the barrier is hit or on the expiry date of the option.

For a call, the payout is received if the underlying asset price is greater than the strike price, and for a put, the payout is received if the strike is greater than the underlying asset price. There are two classes of binary barrier options.

The first are options where a payout of cash or the asset is made if binary and barrier options barrier is hit or not hit during the life of the option. The payout is made either when the barrier is hit, or at option expiry.

For cash payouts, this distinction binary and barrier options only affect the period binary and barrier options time over which the payment is discounted. For asset payouts, however, the distinction is more subtle. If the payout is made when the barrier is touched, then the present value of the payout is equal to the discounted barrier value — since this is the asset value when the barrier is touched. On the other hand, if the payout is made at option expiry, then the present value of the payout is equal to whatever the asset binary and barrier options happens to be at the expiry date, discounted back to the valuation date.

The second class includes options where a payout of cash or the asset is made if the barrier is hit or not hit during the life of the option and if the option is in-the-money at expiry. These are types of knock-in and knock-out binary and barrier options barrier options.

There are other types of digital options available within the FINCAD library, including various flavors of double barrier binary options. Introduction A Binary Barrier Option is a type of digital option for which an option's payout depends on whether or not the asset touched a binary and barrier options level at some time during the life of the option.

Technical Details There are two classes of binary barrier options. Calculate the fair value, risk statistics and probability of hitting the barrier for a binary barrier option with a payoff equal to the asset value if the barrier is touched, or nothing if the barrier is never touched.

Calculate the fair value, risk statistics and probability of hitting the barrier for a binary barrier option with a payoff of a fixed amount of cash if the barrier is touched, or nothing if the barrier is never touched.

Calculate the fair value, risk statistics and probability of hitting the barrier for a knock-in binary barrier call or put option with a payoff equal to the value of the asset if the barrier is touched and the option is in the money. Calculate the fair value, risk statistics and probability of hitting the barrier for a knock-in binary barrier call or put option with a payoff of a fixed amount of cash if the barrier is touched and the option is in-the-money.

Calculate the fair value, risk statistics binary and barrier options probability of hitting the barrier for a binary barrier **binary and barrier options** with a binary and barrier options equal to the value of the asset if the barrier is not touched, or nothing if the barrier is touched.

Calculate the fair value, risk statistics and probability of hitting the barrier for a binary barrier option with a payoff of a fixed amount of cash if the barrier is not touched, or nothing if the barrier is touched. Calculate the fair value, risk statistics and probability of hitting the barrier for a knock-out binary barrier call or put option with a payoff equal to the value of the asset if the barrier is not touched and the option is in the money at expiry, or nothing if the barrier is touched.

Calculate the fair value, risk statistics and probability of hitting the barrier for a knock-out binary barrier call or put option with a payoff of a fixed amount of cash if the barrier is not touched and the option is in the money at expiry, or nothing if the barrier is touched. Calculate the fair value, delta, and probability of hitting the barrier for a path dependent digital option where the payoff is on the expiration date. Calculate the fair value, delta, and probability of hitting the barrier for a path dependent digital option where the payoff is made at the time the barrier is touched.

A barrier option is an option whose existence depends upon the underlying asset's price reaching a preset barrier level. Barrier options are binary and barrier options exotics that are similar in some ways to ordinary options. You can call or put in AmericanBermudan binary and barrier options, or European exercise style. But they become activated or extinguished only if the underlying reaches a predetermined level the barrier. If the option expires inactive, then it may be worthless, or there may be a cash rebate paid out as a fraction of the premium.

Once it is out, it's out for good. Also note that once it's in, it's in for good. In-out parity is the barrier option's answer to put-call parity. If we combine one "in" option and one "out" barrier option with the same strikes and expirations, we get the price of a vanilla option: A simple arbitrage argument—simultaneously holding the "in" and the "out" option guarantees that exactly one of the two will pay off identically to a standard European option while the other will be worthless.

The argument only works for European options without rebate. A barrier event occurs when the underlying crosses the barrier level. While it seems straightforward to define a barrier event as "underlying trades **binary and barrier options** or above a given level," in reality it's not so simple. What if the underlying only trades at the level for a single trade?

How big would that trade have to be? Would it have to be on an exchange or could it be between private parties? When barrier options were first introduced to options markets, many banks had legal trouble resulting from a mismatched understanding with their counterparties regarding exactly what constituted a barrier binary and barrier options.

Barrier options are sometimes accompanied by a rebatewhich is a payoff binary and barrier options the option holder in case of a barrier event.

Rebates can either be paid at the time of the event or at expiration. Barrier options can have either AmericanBermudan or European exercise style. The valuation of barrier options can be tricky, because unlike other simpler options they are path-dependent — that is, the value of the option at any time depends not just on the underlying at that point, but also on the path taken by the underlying since, if it has crossed the barrier, a barrier event has occurred.

Although the classical Black—Scholes approach binary and barrier options not directly apply, several more complex methods can be used:. From Wikipedia, the free encyclopedia.
