Results Research indicates that the suggested prices of the Black-Scholes model are priced higher than the price of call options. In addition, the percentage of deviations and U-theil in ITM profit call options is lower than that of OTM call options, so the pricing efficiency of the Black-Scholes model for the pricing of ITM call options It is more than the price of OTM call options.
