I suspect it is EW. At the moment, I am doing DAX. It is 05:14EST and I have a lag of about 20sec between what is in EW Quote page and the value on the chart. IB TWS (IB feed) value, Ninja Trader, EW Quote page are all in sync, except for EW charts. Frustrating!
Thanks for the posts guys. To CoralReef: You have to contact DTN/IQ Feed and EW to make sure there are no incompatability issues between the data feed and the charting program. They recently helped with some problems I was having with the QuoteTracker charting system, and it is possible that there is a problem somewhere. If not, then it goes back to being a data feed issue, and you will have to try to work around it, or try to get another data feed provider who doesn't have those problems with their charts. IB is one (although they do require high intra-day margins) and Mirus Futures with the Zenfire Data feed is another.
DTN had a change on there feed last weekend. update Ensing to the latest version, maby there is some change....(true tick on DTN)
