Can StockXloader get data for the fund/option/currency XYZ?
It is Yahoo that may or may not support a specific market or a certain security. StockXloader will download data for any market for which Yahoo has data. See the previous question for what exchanges there are data. Certain securities, such as options, can be tricky to find, and BragIt can not help you with that — you will have to search around at Yahoo to see if it is there. For most options, there is no historical data.
