Quote from sonoma:
Why not try IB?
For option trading TOS is a superior platform to IB. That's what you're paying for in higher commissions.
Trade entry and analysis features (such as such as risk graphs) in TOS are convenient and intuitive. IB's feature set is very basic in this regard.
I know option traders who won't move fromTOS to a cheaper platform just for this reason. It's like using a Mac for years and suddenly being forced to use a Windows platform. Both work, but it's all about what you've grown used to.
