Expecting low SPY 4/7

I do most of my work on the /ES, so you can see that post for a more specific level, but I am a dowser and have tomorrow and/or Friday as a low in the SPY/indexes. I lean toward tomorrow and expect a low under $440 in SPY and quick reversal up.
The scenario I have is to stay long until the 15th and definitely SHORT for some fireworks the next week after Easter. We'll see.
