You can include suffixes for multiple exchanges in the same query. For example, you could look for DIS+DIS.L+DIS.TW+DIS.MI to get the prices of DIS on the New York, London, Taiwan, and Milan stock exchanges.

If you include the data specifier x, then the returned data includes the stock exchanges. That makes it easier to tell which data came from which source.

Note that if an exchange is closed due to the time of day or the day of the week, its data is returned as N/A. I’ve modified the example program so it displays a blank string if it cannot parse a value.

Finally the example considers all of the currencies to be dollars, although that won’t be the case for the non-American exchanges.

Download the example and give it a try. The downloaded program is the same as the previous version. All you need to do is enter stock symbols with exchange extensions.
