What we think you saw was due to the rate of updates to the Market Depth data. In particular, the data will not update unless there is a trade or an actual change to the depth data itself. Therefore, during times of low trading, what can happen is that there may have been trades on the Consolidated Tape exchange, but nothing occurring on the NASDAQ itself. Since the Market Depth data comes from the NASDAQ TotalView, there would have to be a change at the NASDAQ for the Market Depth to update.
