Hi Jerry
The indexes (XAO:ASX, XJO:ASX,XFJ:ASX, etc) in fact do work using data from Commsec.
However, a problem relating to the updating of the data for the indexes in MT remains (the same problem apparently does not apply to individual stocks). The problem that occurs is that the indexes are not updating, but if an index symbol was double clicked to open a chart of the index, this would initiate a refresh of the index's data, which would result in the data for the index being updated for the remainder of the session. At least all of that is my experience and is what I currently continue to do.
