thank you Tomasz, you may have just saved me a lot of experimental work!
What do you mean with "...that will have "use only local database"
turned on"? There is only one DB setting in the Rt DB...how to
apply a different setting to the individual imported symbols, i.e., how
do I exclude individual symbols from RT Updates?
btw, What would happen if I simply copied a composite symbol from the
EOD DB to the RT DB (before AB launch), and tried to read it in my
1-min RT DB using Foreign?
thanks for the help,
herman

Hello,
If you are using external data source via plugin, the plugin
takes over any values in the database, so any "imported" values will
be overwritten by the plugin. The only exceptions are
symbols that are EXCLUDED from RT update by "use only local database" option.
You may import data into your IQFeed database using ASCII importer
into separate symbols like XXX_EOD that will have "use only local database"
turned on and later refer to them using Foreign().

Subject: [amibroker] How to fill the AUX fields with EOD data?
Perhaps a smart member on this list can show me an easy way to fill the
AUX1 and AUX2 fields in my 1-Min IQFeed DB with data from my PD EOD
Datbase. For example, during trading and 1-Min Backtesting I need access
to parameters/prices (arrays) that were calculated in my EOD PDdatabase.
It would be great if I could stuff these parameters into the new AUX1
and AUX2 fields.
I am sure there are manual ways to transform and import the EOD data but
this is a task that needs to be performed daily so I would prefer it
automated - or at least simple and foolproof. Also, since my portfolio
1-Min Backtest already takes a very long time to complete, any time
consuming method, like ready a file during the 1-Min Backtest would no
be suitable.
The obvious comment I expect is to use the TimeFrame functions. The
problem is that my 1-min data varies too much from my EOD data and that
the 1-min database gets corrupted too easily - I am unable to match EOD
daily with 1-Min Daily TF results.
Any ideas anyone?
many thanks,
herman
