NDX100: 'Mind the GAP' 4267.45 (Continued).......GAP Fill above.

NDX100 Daily Chart @ Close 12/15/2015

All part of the Frustration as 2015 comes to a Close; the GAP left Open @ 4619.98 NOW Filled in Tuesday Trade.
Losses from here required to maintain the Down- Side Momentum; a Daily Close above 4640 & Santa may yet be 'heard' from into early 2016.
Tactical Short from 4686 remains 'in play'; we know where the Stop is now (Basis the Daily Close > 4640)......with THAT Gap below in our sights @ 4267.45.
