I was downloading some historical data and noticed some discrepancies for one particular contract for the VXX futures. The past 6 years worth of contract data for VXX the end of the minute bar data settles at 13:59:00 for example:

This is end of VXX16
2016/11/16, 13:41:00, 13.65, 13.65, 13.60, 13.60, 8, 3, 1, 7
2016/11/16, 13:42:00, 13.60, 13.60, 13.60, 13.60, 10, 4, 2, 8

2016/11/16, 13:49:00, 13.70, 13.70, 13.70, 13.70, 6, 1, 0, 6

2016/11/16, 13:52:00, 13.70, 13.70, 13.70, 13.70, 11, 1, 0, 11

2016/11/16, 13:59:00, 13.75, 13.85, 13.75, 13.85, 413, 9, 359, 54


However for some reason the VXX 15 contract settled at 16:15:00.

Is there a particular CBOE rule/exception in this contract or is this a data discrepancy issue?
