IB is one of the brokers who charges for cancellations of their option orders. I would imagine that this is because IB as a firm has more cancellations to the exchanges like ISE and CBOE than fills. When possible, perhaps IB customers can be placing several smaller orders instead of one bigger order to save IB from being charged by the exchanges; would this in turn not save the customers from being charged?
Also, would like to know if an individual IB customer has more fills than cancellations if he will not be charged.
