Month/quarter end trading is a somewhat esoteric and potentially frustrating concept for the typical market watcher because it seemingly violates the notion that market move for logical underlying reasons.  To be fair, month-end volatility also has logical underlying reasons, but the logic requires a fairly deep dive (which is why we have a primer on the topic). Today's only econ data is/was Chicago PMI which has already come and gone with no fanfare.  Trading levels are best described as sideways from Friday and the intraday range, far narrower.  If month-end volatility picks up, it would tend to be in the PM hours--especially in the 2pm-4pm ET time frame.
