    Hi,
    forgive for this maybe silly IB TWS related question but I couldn't find what it means, and such things really bug me:
    In Options Trader there is with _some_ premiums the letter "C" in front of the premium, like C2.68.
    Example: MSFT Oct 34 and 35 Puts
    What does this mean?
    Thx

    It means that was the closing price for the option. It also means that particular option has not traded yet.
