Jerry,
is it possible to get Level I quotes from two different data sources IF the status bar only shows L1 quotes coming from one source, in this case the TDA Streamer? (I just want to be 100% sure I'm NOT getting two different Level I quotes from two sources...) On my screen, there's only one little green circle, and when you hover over it it only shows the TDA Streamer.
also, out of curiosity, do you get the TDA feed (TDA Streamer) on your quotetracker?
EDIT: Also ... it appears quotetracker puts in a negative volume amount equal to the cumulative volume for the day after each day in order to reset the volume amounts (and then a corresponding negative volume approximately equal to the positive volume such that their sum equals the true volume amount that had actually traded at that time point) ... furthermore, the large volume spikes I incur almost always have values equal to the cumulative volume for the current day ... that is, as the day progresses the volume spikes tend to get larger and larger depending on how much total volume had been traded during the day... (however, once I clear the chart data and re-backfill over the data all the bad volume spikes vanish ... but they soon return as streaming quotes come in). I wonder if these might be related in some way?
