Over the last few days I have been comparing IB data feed with Dateks data feed. What I have found is that although IB is a much better broker their data feed sucks. I have posted a picture of the QQQ time&sale. (We all know that the QQQ's are a very heavy stock) The tape on the left is with Datek's data feed and the tape on the right is with IB's data feed. As you can see the tape shows a little over one minute of sales. Both tapes are from today (10/03/2002) and are only about 3 minutes apart. How does anyone trade with IB's feed? Could I be doing something wrong? Has IB been slow the last few days or is it always like this? Is IB is in bad need of a new data feed? Has anyone else noticed this?
