Is it worth it to switch from MB to IB ? Hi ! I am thinking about switching from MB to IB. I like MB, did not have any problems. It is my first broker. I am satisfied with the execution speed , it seems like its fast enough. I trade right now about 10.000 shares a day, and 200-500 share lots. Round trip at MB costs $0.02. At IB round trip costs $0.01. It seems like I should save at least $100 a day on commissions at IB. Though I have couple questions about IB: 1) How is the execution speed ? Is it fast enough ? Guys who use IB and trade many times a day, what can you say about the execution speed ? 2) At MB you can avoid NYSE Specialist fee ($0.009 ) by choosing âDAY-NBâ as the order expiration ( in this case MBâs software resubmits order to the NYSE every 4 minutes, and it seems this allows to avoid the fee ). The question is : does IB have similar feature, that allows to avoid NYSE specialist fee ? Thank you for help !
