Eric, Matt

From the technical folks at Track Data (myTrack), confirmed as plausible based on observation of quote/price discrepancies during early market minutes, the problem is that the pipe from NASDAQ gets overloaded so all data distributers suffer this lag. I have been told that NASDAQ has separate sources for quotes and prints that get multiplexed with quotes having priority. Consequently, it is not uncommon for prints to be lagging quotes by several seconds, even minutes in some cases during heavy market activity. I have often watched intraday charts evolving to trace out a delayed path consistent with the quotes I was observing at an earlier time. I suppose it was all those brave "market order" folks getting filled.
