NYMEX Black Swan ~ The March 2012 Crude Oil Futures Quote Loop
On February 13, 2012, starting 13:59:57, quotes for crude oil began queuing. At 14:00:35, all of the queued quotes were sent at once. Again at 14:01:08 the same 38 second block of quotes sent earlier was sent again — old timestamps and all plus a few new quotes. Again at 14:01:18, all quotes since 13:59:57 were sent again. This repeated 12 times.
From a programmer’s perspective, it looks like a system problem caused a blast of quotes that corrupted a memory queue causing the software to believe the queue was full all the time.

Note that as the cycle repeats, it includes a few more quotes (the new quotes + those since 13:59:57). There are 500 quotes between time axis labels.
