USO

Watch next session: track price vs 121–123 short-dated calls; rising put volume/oi, esp < spot; VIX spike >19 reinforcing caution

Net premium: +$34.6M bullish

P/C volume ratio: 0.70

P/C OI ratio: 1.60

Call additions: Short-dated call buys concentrated 121–123 (4/22) and May1 163; smaller LT interest at 200–265. Short-dated call OI ~Xk with elevated vega vs avg, indicating dealer delta activity.

Put additions: Puts clustered 102–119 short-dated and May1 104; aggregate put OI slightly > call OI, providing downside protection.

GEX/DEX consistency: GEX reads negative (~-$5.4M) while DEX shows net long shares (+33.6M); reconcile: negative GEX implies dealers short gamma and add delta into moves, whereas DEX long indicates client-buying of shares—these can offset (delta from option hedging vs direct share flow), producing mixed short-term directional pressure.

OI clusters: Largest call OI at 121–123; sizable put OI band ~102–119 (~25% below spot). Vega-weighted OI confirms short-dated concentration.

Hedging evidence: Elevated IV and vega on short-dated puts/calls; consistent with collars/protective puts by dealers.

Max pain context: Max-pain below spot; short-dated call cluster creates approximate pin risk near 121–123 if OI/vega thresholds hold, but level is estimate and contingent on day-of trading flows.
