Digs, Were you seeing this on a Level I display of TASR, Level II, Isld or Arca books? What was the approximate time of you seeing this? (Time of post is likely but wanted to double-check.) Also, if you PM me your eSignal user name, we can look at additional details to track this down. Thanks.
The eSignal quote for ES was lagging IB's by about 7 seconds for me in the 10:00-11:00 timeframe. They've be in sync since then.
Hello: I noticed the same thing. Cost me a few dollars as I have a 10:00 strategy that got hit pretty good. Late exit was the cause.
