Is the Nasdaq currently a coiled spring or is that shoogly peg about to fail?

The last 3 trading days have been volatile but yesterday we closed ever so slightly up from the close of 3 days ago. It was a real arm wrestle on Friday with the sellers having an enthusiastic go at selling it down in morning trading but buyers stepped up in the last 30 minutes of trading on really big volume to close near the open. The story was very similar yesterday. I'm being cautious until it becomes clear as to whether the buyers or sellers are in charge.
