Digital barrier options pricing: an improved Monte Carlo algorithm | SpringerLink
A new Monte Carlo method is presented to compute the prices of digital barrier options on stocks. The main idea of the new approach is to use an exceedance probability and uniformly distributed random numbers in order to efficiently estimate the first hitting time of barriers. It is numerically shown that the answer of this method is closer to the exact value and the first hitting time error of the modified Monte Carlo method decreases much faster than of the binary barrier option pricing Monte Carlo methods.
Derivative securities have witnessed incredible innovation over the past years. In particular, path-dependent options are successful, and most of them comprise barrier options to reduce the cost of hedging [ 4822 ], binary barrier option pricing.
For these derivatives, exact valuation expressions are seldom available, thus one resorts to simulations multiple times. In this manuscript a new Monte Carlo method is proposed in order to efficiently compute the prices of digital barrier options binary barrier option pricing on an exceedance probability.
Binary options, a. digital options, are popular in the over-the-counter OTC markets for hedging and speculation. In addition, they are important to financial engineers as building blocks for constructing more complex derivatives products. A binary option is a type of option where the payoff is either some fixed amount of some asset or nothing at all. Therefore, binaries are considered to be one of the fastest growing simplified trading products out there, where the trader knows their exact exposure and binary barrier option pricing gains at the time of placing a trade.
The two main types of binary options are the cash-or-nothing and the asset-or-nothing options, binary barrier option pricing expiration values of the European asset-or-nothing and cash-or-nothing binary calls are shown in Fig.
The options are digital in nature because there are only two possible outcomes, they are also called all-or-nothing options and fixed return options FROson the American Stock Exchange ASE. Binary options are usually European-style options. In MayASE for the first time launched exchange trading European cash or nothing-digital options, binary barrier option pricing, which were soon followed in June by the Chicago Board Options Exchange.
Binary contracts are available on a variety of underlying assets: stocks, commodities, currencies and indices. Since the binaries are popular options, much research work has been done on them. For example, Palan [ 20 ] has tested experimentally whether digital binary barrier option pricing can reduce price bubbles in a laboratory setting, and Appolloni et al. Hyong-Chol et al. In addition, Ballestra [ 3 ] considered the problem of pricing vanilla and digital options under the Black—Scholes model, and showed that, if the payoff functions are dealt with properly, then errors close to the machine precision are obtained in only some hundredths of a second.
Barrier options are similar to vanilla options except that the option is knocked out or in, binary barrier option pricing, if the underlying asset price hits the barrier price Bbefore expiration date. Sincebarrier options have been traded binary barrier option pricing the OTC market and nowadays are the most popular class of exotic options. A step further along the option evolution path is where we combine barrier and binary options to obtain binary barrier options and binary double barrier options.
Accordingly, it is quite important to develop accurate and efficient methods to evaluate barrier digital option prices in financial derivative markets.
Most research done to date have focused on option pricing with various methods, for example, Mehrdoust [ 17 ] has proposed an efficient algorithm for pricing arithmetic Asian options based on the AV and the MCV procedures, and Jerbi et al.
In addition, Zhang et al. The Monte Carlo method is very popular and robust numerical method, since it is not only easily extended to multiple underlying assets but also is stochastic and amenable to coding. On the other hand, one of main drawbacks of the Monte Carlo method is slow convergence. In this study, to efficiently reduce the hitting time error near the barrier binary barrier option pricing, inspired by [ 16 ], at each finite time step, we suggest the use of a uniformly distributed random variable and a conditional exceedance probability to correctly check whether the continuous underlying asset price hits the barrier or not.
Numerical results show that the new Monte Carlo method converges much faster than the standard Monte Carlo method [ 18 ]. This idea of using exceedance probability for stopped diffusion is well known in the physics community [ 1116 ].
Finally, we summarize our conclusions and give some direction for future work. The purpose of this section is to introduce two main types of digital options and express their pricing formula. The cash-or-nothing options pay an amount of cash x at expiration if the option is in-the-money. Valuation of cash-or-nothing call and put options can be made using the formula described by Rubinstein and Reiner [ 21 ]:.
Equations of the form 5 are powerful tools to description of many real-life phenomena with uncertainty, and there are some studies on the numerical solutions of them [ 519 ].
Using the Monte Carlo method, the expected value of the discounted terminal payoff is approximated under a risk-neutral measure Qby a sample average of M simulations. with the given barrier price B. The idea is to use an exceedance probability at each time step. Cash-or-nothing barrier options. These payout either binary barrier option pricing prespecified cash amount or nothing, depending on whether the asset price has hit the barrier or not.
Asset-or-nothing barrier options. These payout the value of the asset or nothing, depending on whether the asset price has hit the barrier or not. Rubinstein and Reiner present the set of formulas which can be used to price twenty eight different types of so-called binary barrier options [ 21 ]. Consider a down-and-out cash-or-nothing put option with 6 months to expiration. Using below equations, the value of this barrier digital option is 0.
Simulation of the standard Monte Carlo for this example has the answer 0. Figure 2 shows comparison between the exact value and the new Monte Carlo values for this example and Fig. The exact and new Monte Carlo values for Example 1. Comparison of approximation errors between the standard MC and the improve MC for Example 1. Hui has published closed-form formulas for the valuation of one-touch double-barrier binary options [ 9 ].
A knock-in one-touch double-barrier pays off a cash amount x at maturity if the asset price touches the lower L or upper U barriers before expiration. The option pays off zero if the barriers are not hit during the lifetime of the option.
Similarly, a knock-out pays out a predefined cash amount x at maturity if the lower or upper barriers are not hit during the lifetime of the option.
Using the Fourier sine series, we can show that the risk natural value of double barrier binary barrier option pricing or nothing knock-out is:. Also, Fig. In this paper, we have proposed a new efficient Monte Carlo approach for estimate values of the digital barrier and double barrier options, to correctly compute the first hitting time of the barrier price by the underlying asset. The approximate error of the new method converges much faster than the standard Monte Carlo method.
Future work will be devoted to extend this idea to more general diffusion problems, and theoretically study the rate of convergence of the approximate errors, and also pricing digital barrier options by other methods such as SMC and comparing results, binary barrier option pricing.
