Just to let you know that I got this snippet working now Gergely :-)
Thanks again for putting me on the right track.
What I didn't get though is why I need the " *args, **options".
I read the doc but didn't grasp the why...
Cheers,
Oscar

from data.models import MyichiTickers
tickers_for_exchange = MyichiTickers.objects.filter(exchange="AMS")
for tickerlist in tickers_for_exchange:
print(tickerlist.ticker)
