Net Sweeper Flow
Sweeps netted out across the session instead of read one print at a time. It answers one question: which side is actually paying up on this name.
Reading the chart
Blue is call premium. Red is put premium. When calls are being bought, the blue line goes up. When they’re being sold, it goes down. Same on the put side with red.
That’s why the lines can go negative — a line below zero means that side is net selling, not buying.
Pressure
Pressure is call premium minus put premium, and it’s the bias read.
- +$2M calls and −$2M puts → +$4M pressure
- +$2M calls and $0 puts → +$2M pressure
- +$2M calls and +$2M puts → $0 pressure
That last one matters. Both sides buying cancels out — there’s premium moving, but no directional lean.
