My calculated guess is no since I am trading futures at IB ( other than YM & ES) and I was never charged any mod/can fees.
Yes! Very much so. They charge $100 per cancelation and bill you annually. I know of a fellow that had trigger happy fingers and he got a bill at year end for $35,000. Honest.....
was he cancelling the orders via phone to the desk?? i do not believe they charge for cancelling orders of their platforms
Exactly. However, the only orders I cancel are the ones that go against me - so in the long run, I save money.
