All times referenced in this circular are Chicago time.
How will holidays be handled?
Holiday hours will be addressed in CFE rules and be announced in advance of domestic and
floating trading holidays.
How will expiring contracts be handled on the final settlement date?
Trading in an expiring VIX futures contract terminates on the Business Day immediately
preceding the final settlement date of the contract and is not permitted during extended trading hours for
an expiration day trading session. For example, the expiring July 2014 VIX future will cease trading at
3:15 p.m. on Tuesday, July 15, 2014 at 3:15 p.m. It will not re-open for trading at 3:30 p.m. on July 15,

Are any other CFE products available to trade during extended trading hours?
No. CFE notes that TAS transactions in VIX futures for the then applicable business day may be
executed during extended VIX futures trading hours. The close of trading hours for TAS transactions
executed through CFE's electronic trading system will continue to be 3:12 p.m. Additionally, any TAS
Block Trades or TAS Exchange of Contract for Related Position (ECRP) transactions will need to be fully
reported to CFE by 3:12 p.m. in order to be a TAS trade for that calendar day and to be cleared on that
calendar day. TAS Block or TAS ECRP transactions that are reported to CFE before 3:12 p.m. and
disseminated by CFE after 3:12 p.m. will be disseminated through the use of the trading symbol VX
instead of the trading symbol VXT.
Are VIX futures traded during extended trading hours subject to position accountability
Yes. Position accountability requirements apply to VIX futures at all times. The VIX futures
position accountability levels are 50,000 contracts net long or net short in all VIX futures expirations
combined; 30,000 contracts net long or net short in the expiring VIX future, commencing at 3:30 p.m. on
the Thursday prior to final settlement of that future; and 10,000 contracts net long or net short in the
expiring VIX future, commencing at 3:30 p.m. on the Monday prior to final settlement of that future.
Although VIX futures are subject to position accountability, CFE requires prior notice to CFE
Regulation through the submission of a Position Accountability Form before exceeding a position
accountability level solely for the expiring VIX future and CFE Regulation may not permit the party to
exceed the applicable level. Specifically, a Party must notify CFE Regulation by no later than 10:00 a.m.
on the day a position accountability level for the expiring VIX future will become applicable if the party
was in excess of that level at 3:30 p.m. on the prior business day or if the party intends to exceed that
level when it becomes applicable. Additionally, a party must provide notice at least one full business day
before exceeding a position accountability level for the expiring VIX future during the time period in
which the level is applicable. In no event will a party be permitted to exceed a position accountability
level for the expiring VIX future during the time period when it is applicable without providing the required
prior notice. Parties should refer to CFE Rules 412A and 1202(d) and CFE Regulatory Circular RG14-
013 for further information regarding VIX futures position accountability requirements.
