How to read NATIONALUM's option chain

Each row is a strike: calls on the left, puts on the right. OI is the open interest at that strike and Chg OI the change since the previous session — rising OI points to fresh positioning. The max pain strike is where NATIONALUM option buyers would lose most at expiry, and price often gravitates toward it as expiry nears. The call wall (highest call OI) tends to act as resistance and the put wall (highest put OI) as support, because writers hedge around those strikes. PCR gauges sentiment relative to NATIONALUM's own range, and IV shows how richly each strike is priced.
