It is obvious they are having some server problems. This is my experience:
All GLOBEX backfill (including ES, NQ) very slow, several hours of data missing. Intraday backfill currently takes about 10 min per contract.
NYMEX backfill does not include last Friday. So no indicators or Pivots for a while.
ECBOT data incomplete, last hours of trading days missing for most of the agricultural futures.
NYBOT backfill works, but volume data is not consistent.
EUREX no problems.
IDEALPRO FOREX has spikes, so all the Pivots are wrong on my front-end.
Currently only would trade YM, TF, FDAX and FESX.
If this continues, I'll certainly change brokers (in the past it was more or less acceptable, but never good)
