Unchartheel..IB does offer a discount for Esignal. Im not sure about QCharts. There is an additional fee for LevelI but you can get this from Esignal. Thats another thing I like about IB. I have not found any hidden charges. Most other brokers I have used have always tacked on exchange fees etc.
I dont want to appear to be an IB flag waver. It is what I use and it works for me. Others may have different requirements. I suggest you visit thier website www.interactivebrokers.com
