I get about $50 in cancellation fees per day average for options. This occurs in part because the cancellations are on GTC orders from the day(s) before, and are on ISE, but the fills for DAY orders of today are being placed on CBOE, hence I can't offset them. Is there not a way of getting your day orders routed to ISE? If not, I wish IB would make this possible.
I must be missing something, but just in case: why don't you simply route to ISE in the first place in stead of SMART or CBOE? You choose ISE is the dropdown box for destination.
