I haven't tried to contact DialData in a long time. I kept my subscription current as a backup, so I just started using it. I couldn't find a symbol list for options, so I think that DialData must not cover options any more. DialData seems to be easier to use than Eoddata, and Yahoo. I don't need to use the ProTA symbol list and mappings for them. So far, they have data for all the stocks I follow. Yahoo didn't always have data for some of the thinly traded stocks I follow, and the symbols for preferred stock was different than NYSE in some cases. DialData symbols for preferred stock now uses a dash, and not an * as before, as in AHT-F. Nice and simple. Other sources use all kinds of weird symbology such as AHT^F or the ever confusing AHT.pF or is it AHTpF?. AIEEEE! I also get NAV data on DialData, such as XJQCX for the Net Asset Value of JQC, closed end fund. Just for fun, I was able to download GE stock quotes all the way back to 1/5/1970. That's 48 years of historical data. I wasn't able to download anything earlier than 1970. Based on my experience it is a good idea to have at least two data providers in case one starts having problems.
