Did anyone notice that IB charges higher commission since Feb.1 under unbundled fee structure? My daily commission almost doubled in February relative to January even though my trading volume remains almost identical. From the statement, it is clear there is no rebate pass through from exchanges. For example, in January, the commission for a limit OPG order of 200 shares on nasdaq exchange (SUPEROSES) is about $0.38, while in February, it is $0.88. For limit orders during the day, i received some rebates, but much less than in January. I sent a ticket to IB but received no response yet. I wonder if it is a problem with IB or a new policy. Does anyone have the same problem or know what is happening? thank you.
