Quote from slacker:
Given the same internet connection, only trading 4 instruments, how much better is ZenFire over InteractiveBrokers? Is the difference between ZenFire and IB noticable if trading only a few markets? Or, is the difference only hype?
Depends.
* If you want reliable T&S - IB is out.
* If you do tick charts, IB is out.
Otherwise it is fine.
I am starting recording complete exchange feeds and it is tremendous.
