NDX100: An Error; a GAP & then our Audible.......Still Short

NDX100 Daily Chart @ Close 12/17/2015

GAP below from Monday's 'High' Close @ 4571.2 in need of a Fill (not shown on the Daily Chart); the Error in NOT respecting the Long- Tail 4- Hour Candlestick Monday's Open Trade(signaling a S/T Low) & then our 'Audible' on Wednesday's Close > 4640 post the FED Rate Hike BUT.....amid Lower Crude $'s & Industrial Production #'s that left that nagging feeling......NOT necessarily Disciplined 'stuff' BUT @ times the Auto- Pilot can be disengaged.
So far so good with a reversal & losses; Trade Plan now to take back 1/2 Tactical Short should the GAP @ 4571.2 get closed.
Our S/L? Work in Progress.
