Jerry - I seem to be only able to backfill Nasdaq issues and Futures (however some are not such as HKFE for example). Unable to on things like BA, CAH, T etc. On these it keeps showing backfilling even after nearly 5 minutes have elapsed (although they do backfill the current day relatively shortly).
