Quote from madmunny:
i beleive they bought out the company Attain so now they own the ecn ADFN as well......from the way i understand it....and i could be completely wrong......but i think Knight owns DirectEdge which now owns ADFN
So when i need to status an order i placed on ADFN....i have to call DirectEdge.....where i use to have to call Attain.....
Hope that helps out a bit
