base 4.5; -1 large negative GEX (trend) vs mixed flow; +0.5 spot 1.3% from MP; net neutral on IV
Term structure: Front-end IV is elevated (1-3d ATM 35.9%-31.3%) then normalizes into the 20-22% range for 30-45 DTE. Good calendar roll/backspread opportunities but avoid selling naked weeklies into front-end vol spikes.
Spot vs MP: Spot $659.22 is above nearest max pain $655.00 (2026-04-08) by $4.22 (~0.64%) — spot currently sits between MP and short-term call pin magnets
GEX regime: Trending / Breakout risk (GEX = -$1.2B): dealer short gamma (negative) — markets can trend and accelerate; pinning pressure reduced
Gamma flip: ~$535.00 — Gamma flip is ~ $535 (well below spot). Dealers switch to being long gamma below that; not actionable near current spot.
OI concentrations: Call walls: 670/673/675 (4.6k–6.2k OI each near-term); Put walls: 645 (12,472 OI), 630 (10,010 OI), 655 (7,494 OI). Large structural put OI clusters concentrated well below spot ($535, $500, $590).
#1call credit spread
Sell 670 / Buy 675 call spread exp 2026-05-08 (31 DTE)
Near-term GEX concentration shows multiple pin magnets at 670/673/675 (+$6.5M at $670 etc.). Term structure: 31d ATM IV ~21.8% giving decent premium; negative GEX favors defined-risk to avoid naked gamma. Selling call spread above the pin collects call-rich premium and aligns with the market's short-term pinning at those strikes.
Mgmt: Take profit at 50-65% of max credit; roll up-and-out (add DTE) if spread tested and IV rises >20% vs entry; close if underlying prints and closes above $676.29 (1w EM upper guardrail) or if net delta of account flips large positive; cut losses if spread >50% of max loss.
#2iron condor
Sell 645/640 put spread + Sell 670/675 call spread exp 2026-05-08 (31 DTE)
Combines the heavy put OI at 645 (12,472) as support with call pin magnets at 670-675. Normal IV in the 31d band (~21.8%) means you can collect a meaningful wing premium while keeping defined risk given negative GEX. EM 1w bounds ($642.14/$676.29) provide a sensible risk envelope.
Mgmt: Close at 50% of max profit; tighten or buy back call side if price closes >$668 for 2 consecutive sessions or if intraday touch of short call 670; roll put side down-and-out if price collapses below $642.14 or if short strikes are tested with >3 days to expiry.
#3put spread (CSP-style defined-risk)
Sell 645 / Buy 640 put spread exp 2026-05-08 (31 DTE)
Large put OI at 645 (12,472) suggests dealer hedging and support; selling the 645/640 put spread takes advantage of put demand while limiting downside risk in a negative-GEX trending regime. This is a more bullish-tilted defined-risk alternative if you want a one-side trade.
Mgmt: Take profit at 50-65%; roll down-and-out if tested and market shows sustained sell pressure below $642.14; close if spot closes >$660 with IV contraction (to lock profit) or if spread reaches 50% of max loss.
#4calendar (buy long-dated / sell near-term)
Sell 2026-04-14 short call at 670 and buy 2026-05-08 670 call (calendar) — use 31d back month
Front-end IV is spiked (1-3d ATM 35.9%-31.3%) while 31d IV is lower — selling the short-week against a longer-dated long can capture decay and implied vol term structure. Use small size given negative GEX.
Mgmt: Close the short leg if price prints and closes above 670 before short expiry; take partial profits if short-leg theta decays >75% of initial value; avoid rolling short-week into earnings or large flows.
!Large negative GEX = -$1.2B (trending) — accelerations and directional moves more likely; prefer defined-risk spreads over naked premium
!Front-end IV spike: 1d ATM 35.9% and 2-3d 32.8%-31.3% — highly variable; avoid selling naked weeklies into this elevated short-end IV
!Unusual call activity at 668/677 short-dated expirations (high volume/OI) and heavy net call flow at 660/656 — potential one-sided flow that can push price through short strikes
!Max pain cluster near $651-$657 is below spot but near-term GEX pin magnets at $670-$675 are above — watch for a two-way squeeze if flows align (fast move invalidates side-biased positions)
!Gamma flip is far below spot (~$535) but structural put floor $495-$600 exists — a large downside acceleration would hit deep put liquidity; keep position sizes moderate
