Quotetracker with money.net feed.
Not cumulative (853502 at 14:23:28 is less than 854002 at 14:23:20).
Data recorded in "real time" not back fill.
Between 14:23:05 and 14:23:55 inclusive there were five quotes and trades on back fill, far more trades (8)and quotes without trades (7) on the "real time" record between 14:23:05 and 14:23:28

Somethings seems to be seriously amiss. As I said my data is also from Money.net but bears no relation to yours.
I did notice a few days ago they had a notice saying something about data feed problems but the notice has gone now. Perhaps you could get in touch with Money.net and ask them whats going on. Alternatively Jerry M at Quotetracker may have had queries and be aware of data corruption.
If you do get in touch with Money.net or JM and get an answer please let us know.
Cheers

Below are email to and reply from quotetracker. They appear to believe that the spikes are genuine. I also emailed money.net but have not had a response apart from acknowledgement.
I'd be very grateful if someone could explain the significance of these very large volume spikes with little price change.

Subject: volume spikes
Is it possible to do anything about very large volume spikes. Even if volume is capped they seem to raise the average volume so that other volume bars are virtually undetectable. they cannot be deleted unless they are associated with a highest or lowest price spike.

Not much can be done about volume only spikes because total volume has to equal as reported - can not be reduced. Cap % is the only mechanism that QT for provides (which is essentially for display). You may try to increase the chart frequency to spread the volume over a longer period as well.

QT will only report what it receives from money.net. Comparing with other data sources I'd say that the latter was erroneous on this occasion. Often you'll see large volumes on small price spreads under active conditions (for whatever reason) when the MMs could buy or sell into substantial public selling/buying respectively, the low spread on high volume being an indication of the MM falling over themselves to trade immediately
