Quote Tracker has talked to IB. IB confirms there is a problem with the feed and they are working on it. Also, thnx for the post LIbertine.
For those interested here is an update emailed to me from QT: " Update - It apparently is now through the ISLAND exchange rather than SMART default. IB is still working on this issue so that is transparent but for now in QT you should be able to get quotes on it through the API in QT by using the ISLAND exchange prefix such as ISLAND:INTC " Mazel" As of now i dont have any info re Sierra Chart.
Thing there is, if you're sending an order via the API then presumably it will only be routed to Island so no guarantee of best execution. Plus you get charged for routing orders to anywhere other than Smart on the API. Anyway, I'll fire things up in a few hours and if I still see the problem then I'll get back onto IB CS myself.
