    Hello Amu,
    It’s nothing to be concerned about.
    There are so many strike prices, that the symbol for all cannot begin with the same three letters.
    Example, the February 410 strike, the 510, 610, 710 etc cannot all be RUTBB [The first ‘B’ represents the month and option type. ‘B’ is Feb calls; the 2nd B represents the strike, and ‘B’ is for strikes that end in ’10’].
    Thus, when an option has strikes that span more than 100 points, the symbols must change to accommodate that duplication.
