From 'pullbacks' to a 'correction' (S&P 500)

Setup
Still Bullish. Be patient for entry near end of the corrective move lower

Evidence..
-Trend is up, no top pattern
-No longer 'dips' to 50 DMA, now into a 'correction' with possible move towards 100 DMA
-Large bearish engulfing weekly candle
-The 4 month old trendline has broken.
-RSI has dropped under support - but not yet characteristic of bearish trend by going oversold
-Price has landed at a demand zone under 6500 (could rebound from here)

Signal
Looking to go long on another test of the demand zone OR
at next supports found at matching lows of 6350 then 6200
