If you are already paying for the "professional" exchange fees for one software package, are you able to somehow avoid paying this for additional software/charting packages. Example: If I pay for CME quotes via IB do I have to also pay the same fee to tradestation. Or if I pay the 130.00 bucks a month for NYSE quotes in tradestation do I have to also pay that fee if I want the quotes trough IB. It just seems like nonsence to pay these exchange fees on every platform you might use. Any info is appreciated. Thanks
