SPX Elliott Analysis w/ commentary

I am seeing a post FOMC drop to the lower diagonal trendline (@ 3950-sish), followed by a lazy recovery targeting a new high of the 4,175-4,200 ish areas (finally completing ending diagonal Wave C) Expecting this new top to coincide with the FEB 18th options expiry.
THEN after expiry I'm looking for a larger pullback retesting of the 3.650-ish areas
