Symbol, OptionSymbol, Exp, Strike, and Type are calculated by parsing the option code.
OptionCode is the option code in the standard Yahoo! Finance format.
OptionSymbol ends with 7 for Mini Options, and with 1 for some options before splits.
The ChangeInPercent, ChangePercent, and Percent values are calculated by RealTimeToExcel and are the same. The Mark value is calculated as (Bid+Ask)/2.
Use Strike~0 to find the ATM strike, Strike+0 or Strike-0 to find equal or the nearest strikes, and Strike+1 and Strike-1 to find the nearest strikes above and below the strike.
