Our third step is to compare the number of mini flash crashes during
the test window to the number of mini flash crashes in Control Period 2, which contains all three - minute window during throughout normal trading hours during the same 10 proceeding weekdays.
Indeed,
the test window experienced more trades executed than any other 9:30 — 9:33 window during Control Period 1.
This test window is between the market's opening for regular trading, 9:30, and the beginning of the October 2014 U.S. Treasury Bond Flash Crash at 9:33 [1].
The test window experienced 1 mini flash crash per 56,183 trades, whereas on average during the control period, 1 mini flash crash was experienced per 186,407 trades.
While the literature suggests that mini flash crashes occur most frequently at the beginning and end of trading hours [21], we investigate all three - minute windows in the control period to check that the activity seen in
the test window is truly anomalous from normal trading activity.
The analysis first identifies the number of mini flash crashes in the three - minute
test window of 9:30 (inclusive) and 9:33 (exclusive) on October 15, 2014.
A control period of two weeks is also sufficient to determine baselines of data against which to compare the number of events in
the test window.
The number of mini flash crashes experienced during
the test window relative to other 9:30 — 9:33 windows is abnormal because (a) the thirteen mini flash crashes during
the test window is 2.6 times greater than the greatest number of mini flash crashes experienced during any other 9:30 — 9:33 window; (b) the eleven unique equities that experienced a mini flash crash during
the test window is 2.2 times greater than the greatest number of unique equities which experienced a mini flash crash during any other 9:30 — 9:33 window; and (c) the frequency of mini flash crashes normalized by the number of trades executed is greater during
the test window than it was during any other 9:30 — 9:33 window.
The number of mini flash crashes during
the test window on Oct. 15 is 2.6 times greater than the greatest number of mini flash crashes experienced during any other 9:30 — 9:33 window.
This repeated counting is not an issue, since the objective of the analysis is to measure the number of mini flash crashes in
the test window against the number of mini flash crashes in each window of similar duration during the control period.
There is not a single three - minute window during Control Period 2 that experienced more than five mini flash crashes, whereas
the test window experienced thirteen mini flash crashes.
The number of unique equities that experienced mini flash crashes during
the test window is 2.2 times greater than the greatest number of unique equities that experienced mini flash crashes during any other 9:30 — 9:33 window.
However, despite the increase in the number of trades executed,
the test window still experienced more mini flash crashes on a normalized scale than any other 9:30 — 9:33 window during Control Period 1.
The number of mini flash crashes in
the test window is compared to two control periods.
In the three - minute window on October 15, 2014 — henceforth referred to as
the test window — we find thirteen mini flash crashes.
Still, after accounting for the possibilities of some specific equities experiencing a disproportionate share of mini flash crashes, and variations in trading activity creating more opportunities for mini flash crashes to occur, the evidence continues to suggest that an abnormal level of instability could have been detected in the U.S. equity market during
the test window on October 15, 2014.
For instance, twelve of the thirteen mini flash crashes during
the test window occurred in the sixty seconds between 9:30 and 9:31.
