Embedded format to import Aux1 Aux2

I'm trying to import Aux1 and Aux2 as separate file but it fails...

dafault.format exists but I leave it empty

Is Aux1 and Aux2 quotation data??

Just found that
$ALLOWNEG 1
was needed

Not only that. You need to follow instructions given in the Knowledge Base

Thank you for your response.

I think I will use synthetic tickers because I will probably need more data down the road.
I'll use just EOD data for the synthethic data, like maybe 5 synthetic tickers for every regular ticker.

The database is all US stocks, around 6k symbols. One minute data.
Will these synthetic tickers degrade explorations performance?

I suppose I will have to exclude them in afl code with some flag. Planning to use Aux1 set to 1 in all synthetic tickers to exclude them.

I will use Foreign calls to lookup daily data in them.
