@danmcco, not sure what you mean by the second sentence, but for index options that have non-standard expiration dates, you must specify them in the ticker symbol as mentioned earlier in this thread. In any case, are those valid options listed on Yahoo? You can check this on the Yahoo Finance web site. If you can find the correct Yahoo ticker, please let me know what it is so I can make sure that our software is generating it correctly.
@gawler51, same problem, it appears that the QCT option you specified is not listed on the Yahoo option chain for QCOM (http://finance.yahoo.com/q/op?s=QCOM&m=2010-03). Keep in mind that although these may be valid option tickers, if they are not listed on Yahoo, you will not be able to get quotes for them.
