import com.tigerbrokers.stock.openapi.client.struct.OptionFundamentals;
import com.tigerbrokers.stock.openapi.client.struct.enums.Right;
import com.tigerbrokers.stock.openapi.client.util.OptionCalcUtils;
import java.time.LocalDate;

public class Test {
  public static void main(String[] args) {
    OptionFundamentals optionIndex = OptionCalcUtils.calcOptionIndex(
            Right.CALL,
            243.35, //stock price
            240,  //option strike price
            0.0241,  //risk free rate
            0,  //dividend rate
            0.4648, // Implied Volatility
            LocalDate.of(2022, 8, 12), //settlement date
            LocalDate.of(2022, 8, 19));  //option expiration date
    System.out.println("value: " + optionIndex.getPredictedValue()); //predicted option price
    System.out.println("delta: " + optionIndex.getDelta());
    System.out.println("gamma " + optionIndex.getGamma());
    System.out.println("theta " + optionIndex.getTheta());
    System.out.println("vega: " + optionIndex.getVega());
    System.out.println("rho: " + optionIndex.getRho());
  }
}

example result：
