The target of SPX pullback:
First target 1650 reached
2nd target about 1630 (support+MA20) should reach
3rd target Gap 1597 may not reach
My wild wild guess: 1687-1627-1649-1589->...
When everyone got used to buy dip, the market dynamics changed.
Continue holding remaining SPY shorts with stop loss adjusted to 165.6.
"2nd target about 1630 (support+MA20) should reach" is still effective.
SPY shorts exited with good profits. ST direction is not clear, it may bounce first then retest 164.
SWING trade @ R/S on either direction is probably best.
