Thanks, My German is not that great but is it correct that IB is much cheaper than these 3 brokers?

Quote from Mel Funktion:
Correct, iam located in germany and as far as I know german/european brokers are much more expensive than US brokers.
Up to 5/6 Euro for a Roundturn (thats ~8$ USD) and extra fees for realtime data and/or account maintenance and other bullshit.
I pay 6 â⬠Euro per Roundturn and 80â⬠for "historical data" package in the moment. Just faxed them my account cancellation request and want to move to an american broker. Just need to decide between Mirus or Amp Futures.
