I downloaded Amibroker and I created a list of Australian stocks, which I imported. I am able to download the historical prices from Yahoo Finance. I would like to have the XAO downloaded as well. I tried using XAO, XAO.AX, AORD, AORD.AX, ^AORD, ^AORD.AX but all these are reported invalid. How can I download the All Ordinaries?
