haha i don't know. However look at SPY today at 1000, 1036, 1039, and 142. These kinds of things happen very often. Not always though
Volume profile, TICK, VWAP, and +/- 1, 2, 3 standard deviation bands of VWAP so important for algo trading. Don't be left home without them!
Edit: and, how could I forget, pivot points as well
