For the fall 586.12 to 574.41 4SPY retraced 78%. So double bottom is what Hence, expect.
For the fall 583.32 to 576.36 582 is the level to short for 578-579. If this is broken, we can expect 576 levels which is 200 averages in one hour time frame.
The issue we have at the moment in one hour is SPY made LL at 580.38 and 574.41. But no divergence in oscillator. Hence, I don't see much downside. At the moment.
Go long above 585 and short cover at 579 578 levels. Maximum downside as mentioned is 576 levels as of now.
