Shows the SPY net call and net put premium through the session.
What you see
- Crypto. Call premium in green above zero, put premium in red below. 0DTE uses 5 minute bars, WEEKLY 1 hour bars. A strip totals calls, puts and the difference.
- US equities. Running net call premium (bought minus sold) and net put premium through the session, or their difference with NET.
What to look for
- Sustained one-sided flow over several hours or days. It is more reliable than a single spike.
- A sudden put premium spike: a fear bid for protection.
