We show that the Malliavin calculus approach is indeed very convenient to work with, even though the underlying theory is rather abstract. The work of Harrison and Kreps though full of complex mathematical results, builds on those assumptions and correctly demonstrates that the prices of all assets, suitably discounted at the risk-free interest rate, follow a martingale, which is a random variable whose value is not expected to change Chance, D Here we basically consider ordinary stock options that might become worthless if the exchange rate hits some predefined barrier level during a first part of the time to maturity.

Barrier options, lookback options and Asian options Path dependent options: payouts are related to the underlying asset price path history during the whole or part of the life of the option. Look‐barrier options have many similarities with compound options and can be viewed as barrier options over [t, T 1] on a contract with T 1 payoff equal to the present value of a lookback option on the interval [T 1, T 2].

Pricing the look‐barrier options is a lot more difficult than pricing the extreme spread lookbacks of the previous section.
