Just found this in the 908 notes: "Customer BookTrader Recentering. The Re-Center section of BookTrader configuration has been modified to allow you to specify the number of rows away from the current center the midpoint or last price must be before it will recenter." This is a very welcomed feature following a change that was made in 891. This should save a lot of repeated clicking to recenter throught the day. I would like to thank DAV at IB who I know was very helpful in pushing for this change. Thank you very much DAV.
