Quick read
Upside lean. The trend stack is positive, but confirmation still matters. The risk stance is YELLOW: the environment argues for caution, so every idea is cut to 0.50x normal size until the tape earns more.
- high-impact events near: PPI (Producer Prices)
This is a conditional read, not a prediction. Direction matters only after price accepts or rejects the levels below; an invalidation overrides the initial lean.
Trend and volatility evidence
SPX is referenced at 7,799.63 from Intraday 1M (2026-08-13 15:45:00-04:00). At 3.2% above its 20-day average and 3.9% above its 50-day, price holds the trend-following configuration: both benchmarks sit underneath as support rather than overhead as obstacles. Realized 20-day volatility is 13.7%; 14-day average true range is 84.4 points (1.1% of spot).
VIX at 14.63 sits in the Calm regime and held steady across the week — the options market is not paying up for trouble. The one-day expected move of about 49.7 SPX points runs below the 14-day average range — options are pricing quieter sessions than the tape has been printing. Expected move is a volatility-derived range estimate—not a forecast or hard boundary.
Important SPX levels
These are decision zones assembled from the prior session, moving averages, implied volatility, and the latest validated options-positioning snapshot. Treat each as an area where acceptance, rejection, or a clean break can change the play.
| Reference | Level | From spot | Source | How to use it |
|---|---|---|---|---|
| Expected-move upper | 7,849.3 | +0.6% | Implied volatility | One-day statistical reference, not a boundary |
| Call wall | 7,800.0 | +0.0% | Options positioning | Potential overhead reaction zone |
| Gamma pin | 7,800.0 | +0.0% | Options positioning | Potential magnet / congestion zone |
| Estimated gamma flip | 7,782.5 | -0.2% | Options positioning | Estimated hedging-regime boundary |
| Prior high | 7,766.0 | -0.4% | Prior session | Range ceiling / acceptance test |
| Put wall | 7,750.0 | -0.6% | Options positioning | Potential downside reaction zone |
| Expected-move lower | 7,749.9 | -0.6% | Implied volatility | One-day statistical reference, not a boundary |
| Prior close | 7,748.5 | -0.7% | Prior session | Baseline reference |
| Prior low | 7,737.9 | -0.8% | Prior session | Range floor / acceptance test |
| 20-day average | 7,555.3 | -3.1% | Trend | Short-term trend reference |
| 50-day average | 7,504.0 | -3.8% | Trend | Intermediate trend reference |
Strategy scorecard
Every structure stays visible—including reduced, avoided, and blocked ideas—so the page shows losing or low-conviction alternatives instead of presenting only the most attractive setup. Scores compare strategies within this run; they are not win probabilities.
Score is the playbook’s own edge tally—the sum of its signed reasons for that structure—and the verdict is a threshold on it: ≥ +2 favored · ≥ +1 ok · > −1 reduced · ≤ −1 avoid. Blocked (−9) is not a low tally but a hard veto—debit spreads are switched off outright in elevated or stressed volatility.
Put Credit Spread
Ok- positive gamma, but spot below pin -- support is overhead, less ideal
- trend UP (5d +1.2%)
- calm VIX: thin premium but stable
- high-impact pre-open print today: wait for the release to clear
Conditional guidance
Short strike below put wall 7750 and at least one expected move (~50 pts) under spot; respect the $5k max-loss cap.
Iron Condor
Reduced- strong positive gamma + calm vol: pin day favors two-sided theta
- spot already hugging pin 7800
- event risk within hold window
Conditional guidance
Wings outside call wall 7800 / put wall 7750.
Call Credit Spread
Avoid- spot pressing call wall 7800 in positive gamma -- fade zone
- fighting an uptrend: GEX live book saw 9% win rate doing this
- disabled by default in the GEX live policy (call credits lost -$2,245 on 30d)
Conditional guidance
Only above call wall 7800 rejection with confirmation; small size.
Call Debit Spread
Avoid- calm+pin decay kills debits (0/6 max-loss on the 5/29 0DTE study)
- event-day gap risk on a long-premium position
Conditional guidance
Direction-aligned only; take profits fast -- decay is the enemy.
Put Debit Spread
Avoid- pin decay kills debits
- no aligned downtrend
- event-day gap risk on a long-premium position
Conditional guidance
Only on confirmed breakdown (put wall loss) while VIX still calm.
Confirmation-gated play map
These are hypothetical planning examples generated by the daily playbook. A trigger alone is insufficient: the listed confirmation must occur, and the listed invalidation ends the thesis. Strike references can be stale by the time you read this.
PPI (Producer Prices) hot → gap down → drop HOLDS
Why it is on the map: momentum continuation; direction confirmed by the tape; aligned debits are the one validated debit setup (direction-gated, not bought blind)
PPI (Producer Prices) hot → gap down → RECLAIMS (failed breakdown)
Why it is on the map: failed breakdown + post-event vol crush = best credit entry of the week; the flush priced the bad news
PPI (Producer Prices) cool → gap up → HOLDS
Why it is on the map: event risk cleared + vol crush tailwind on short premium
PPI (Producer Prices) cool → gap up → FADES back into range
Why it is on the map: two failed drives + positive gamma = pin day, harvest both sides
Put wall 7750 breaks and stays broken
Why it is on the map: largest gamma support gone; FIRST close/roll any threatened short puts (losers run 5.7x winners), then the aligned debit rides the acceleration
Call wall 7800 test and rejection
Why it is on the map: dealers fade into their long-gamma wall; small, defined, take profits fast
If / then scenario plan
If PPI (Producer Prices) at 08:30 ET prints (either way)
Do not position into the print. The gap direction AND whether it holds decide the trade -- see the price-action play map for the specific spread per branch.
If SPX tests call wall 7800 (+0.0%)
First test in positive gamma usually stalls: take profits on longs, do not chase. Acceptance above on closing basis means walls re-rack higher -- skip call credits.
If SPX loses put wall 7750 (-0.6%)
Largest gamma support is gone. Close or roll threatened short puts immediately (losers in this book average 5.7x winners -- cut, don't hope); the aligned put-debit continuation is in the play map.
If Spot oscillates around pin 7800 into the afternoon
Classic pin day: theta strategies win, debit lottos lose (calm+pin went 0/6 on 0DTE debits). Sell premium at range extremes, target the pin into the close.
If VIX crosses above 22 intraday
Regime break: stop opening credit spreads, tighten stops on open ones. Elevated-VIX debit blocking stays on -- being flat is a position.
If Orderly dip toward 7750 that holds (one expected move ~50 pts)
Preferred entry: sell the put credit into the dip rather than at the highs -- better strikes, same thesis.
