Hi everyone, Does anyone know if IB charges fees for US option order modifications? From the homepage it seems that they do charge for cancellations and imply that this might also be the case for modifications. In my strategy I need to purchase/sell options at aggressive prices inside the spread therefore I likely need to update orders quite a few times before getting executed.
They treat option order modifications like a cancellation and subsequent re-entry. Note though if the trade finally executes, you get (part of) the fee back as explained on their fee site.
As discussed in here, we have lowered our modification and cancellation fees for US Option orders http://www.elitetrader.com/vb/showthread.php?s=&postid=3779316#post3779316
And I see from the fine print that the no charge for modifying/cancelling combination orders still stands.
