No, I didn't need to build the Ark, it stopped raining in time, and the
houseboat was just an idea - still thinking about the idea though :-)

I think that you are still missing the point, Donald. I wasn't looking for
a *specific* script to suit a *specific* data source, but a *general*
script
with enough flexibility to suit most of the popular ASCII formats. This
should be builtin to AmiBroker, but until it is, we all need some way of
getting EOD data (from whatever source) into AmiBroker. If you go to:
http://www.paritech.com.au/PRODUCTS/Data/emails.htm
you will find samples of most of the popular ASCII formats available. The
main problem with AmiBroker's ASCII import function at the moment, as I
said earlier, is the fact that you need the '$NAME' variable on one line,
and the '$FORMAT' variable on the next line. If AB was flexible enough to
include the 'NAME' variable in the '$FORMAT' variable then there would be
no
problem. Most of the various formats use some variation on the format:
CODE,DATE,OPEN,HIGH,LOW,LAST,CLOSE,CUM. VOLUME,CUM. VALUE, and one of the
ones that I am looking at at the moment has the following options:
CODE,LAST,HIGH,LOW,VOLUME,ASK,EPS,FRANKING,OPEN,PAYDATE,VALUE,SELLERS,BUYERS,
PREV.CLOSE,BID which just about covers everything :-)
> The header above has tickers, but does any data include the full name,
too?
No, all the ones that I have seen lately have just got the ASX code, not
the full name, in the datasets.
> Do you have a data source that includes corrections for yesterday's
data?
No, to date I have found NONE at all that even admit there are errors in
the data :-)
> Do any suppliers include indices?
Yes, most of the ones that I have looked at recently carry the Indices as
part of the dataset, under the ASX codes of XAO (All Ords), etc. Some even
carry major overseas Indices like the DJIA, FTSE etc, but usually under
some obscure code, so you wouldn't be able to mix-and-match the datasets.
The hunt still goes on for the perfect Aussie data source :-(
Bye for now,
Terry
