Here is what I am watching in US broad equities in the May option expiration. There is support for the SP around 1321-1324. If it breaks that and sticks the close there might be something to this, moreso than the usual option wash and rinse.
On the NDX chart the intermediate uptrend is more pronounced with strong support at 2330.
