Reading NATIONALUM's positioning
- PCR 0.83 — More call OI than put OI is open across NATIONALUM's chain. Call writers dominate, which can act as a resistance cap on rallies near heavily-written call strikes.
- Max Pain at 330 — The strike at which the maximum number of NATIONALUM option contracts would expire worthless, minimising payouts for option writers. Often acts as a magnet for price into expiry.
