I have switched to a bullish bias recently ... Tried to fill the gap, but failed. Since then SPY is proving to be stubbornly bullish in my mind.
A close above the previous 4 hour high is bullish, and it might also be what's needed to finally breakthrough the long-term up trend convincingly. If it it does, the all-time highs will be retested.
Notice, SPY sits comfortably above the 50 and 100 day moving averages. There is good volume, and the RSI is strong.
