Saschabr - Yes, $50 commish to waive fees for futures account would be no problem. The point is, all accounts should be waived with X amount in commissions generated if, as I suspect, IB's problem is really about supporting the cost of inactive accounts. I have emailed IB management on this issue.. no reply yet.
However, today the IB data feed was basically lagged useless from the fed announcement until the end of the day. This is not the first occurance of seriously frozen/lagged data with a sudden burst of volume. IB should not even think about charging for such poor data until they can remedy what appears to be a capacity issue and guarantee better performance.. IMO.
