How to read these figures
Every reading here is one we computed from that session. The history plots the difference between aggregate call and put premium, scaled to the largest absolute reading in this window.
Institutional-looking activity is inferred from trade size and shape. Sweeps span multiple venues. Neither tells us who traded or guarantees a directional move.
Relative options cost compares this stock with its own past year. It is not the stock's implied volatility quoted as a percentage.
