If you are referring to the erroneous spike to 212.97 at 3:59 on SPY, I can tell you that this happened cross-platforms. Must have been an algo going haywire in a millisecond.

I bet to differ, not all platforms.

Here is an update on the data spike for SPY near the end of trading on December 19, 2014. The trades were real and were not cancelled because they were not considered clearly erroneous transactions.
Pursuant to Rule 11890(b) NASDAQ, on its own motion, in conjunction with BATS, Direct Edge, FINRA and NYSE-Arca has determined all trades in security SPDR S&P 500 ETF Trust (SPY) executed between 15:59:00 and 16:00:00 ET today (yesterday) will stand. This decision cannot be appealed
