Common setup

Two setups on the SPY today.  First was a long off the IB-low coinciding near the Open price on a reverse divergence.  Since the 'trend' is still up (for my timeframe) buying common support levels (trend line support, IB-low, Open price, previous day's high, 20-period MA were all there) was still a highly probable trade. 
The short entry was based on the 2b criteria setting up on the 15-min 3/10macd and the trigger was the 5-min setting up the 2d-to-2c continuation pattern (a.k.a. Bear flag).  Exit was at the 100% projection.  I took everything off at the one target out of an error in judgment.
