“…For instance, Koekebakker et al (2007) constructed a freight fitting model based on lognormal distribution, and deduced the closed pricing formula of Asian call and put options with fixed execution prices, which significantly improved the pricing and hedging accuracy. Based on Monte Carlo simulation, Wang et al (2009) constructed the Asian option pricing model with the lognormal distribution and fixed strike price. Haug (2021) gave the Turnbull and Wakeman (1991) adjustment closed formula to calculate the settlement price of freight options on the European Energy Exchange.…”
