Technical Indicators
Quick-reference for reading the values below. Indicators combine to confirm a view — no single one is a trade signal on its own.
Trend Indicators
- SMA 20 / 50 / 200 — price above = uptrend, below = downtrend. SMA 50 crossing SMA 200 is the golden/death cross.
- EMA 12 / 26 — faster-reacting averages; 12 above 26 is short-term bullish.
- MACD — bullish when MACD > signal (green badge), bearish when below. Divergence from price often precedes reversals.
- ADX (14) — trend strength regardless of direction. <20 range, 20–25 weak trend, 25–50 trend, >50 strong trend.
- +DI / −DI — +DI > −DI favors bulls; the reverse favors bears. Read alongside ADX.
Momentum Oscillators
- RSI (14) — <30 oversold, >70 overbought. 40–60 is neutral; trending names can stay extreme.
- Stochastic %K / %D — <20 oversold, >80 overbought. %K crossing %D is an early momentum signal.
- Williams %R — inverted scale: <−80 oversold, >−20 overbought.
Oscillators work best in range-bound markets; in strong trends they give premature reversal signals.
Volume & Volatility
- Bollinger Bands — price at upper band = overbought, lower = oversold. Narrow bands (squeeze) often precede expansion.
- OBV — cumulative volume; rising OBV confirms uptrend, falling OBV confirms downtrend. Divergence from price is a warning.
- Vol SMA 20 / Vol ROC — today's volume vs. 20-day average. Positive ROC with price move = conviction.
- ATR / True Range — average daily $ move; sizing and stop-loss reference.
- HV 20 / 30 / 60 — realized (historical) volatility. Compare to IV on the options cards: IV > HV = rich premium.
Confluence matters: trend + momentum + volume agreeing carries far more weight than any single indicator. For how these feed the spread scanner score, see the algorithm docs →

Spread Scanner GPU
Each spread is ranked by a composite score built in three stages. Full documentation →
Stage 1 — Base Score (GPU scanner)
score = P(profit) × (credit / spread_width)
P(profit) from short leg delta (1 − |delta|), penalised above 85%. Credit uses mid-price to handle illiquid chains fairly.
Stage 2 — Skew Adjustment (±25% cap)
RR and BF (30-delta) from the persisted per-symbol skew snapshot — wing strikes picked by real greeks.delta, not a moneyness proxy. Put skew boosts bull puts, penalises bear calls. High butterfly boosts iron condors. Calendars are skew-neutral.
Stage 3 — Technical Overlay (±50% cap, 5 groups)
Group 1 · Directional Bias (±0.25)
- RSI <40 bullish / >60 bearish
- MACD crossover + histogram trend
- Price vs SMA 50 & SMA 200
Group 2 · Momentum (±0.10)
- Stochastic %K <20 / >80
- Williams %R <−80 / >−20
Group 3 · Volatility (up to −0.25 / +0.15)
- Blended ATR + straddle expected-move penalty
- Bollinger Band signal (+ counter-trend penalty)
- BB width — vol contraction boost for ICs
Group 4 · IV Regime (±0.15)
- IV rank ≥ 75 → strong boost for credit spreads
- IV rank < 25 → penalty (selling cheap vol)
Group 5 · Liquidity (penalty up to −0.10)
- Min open interest across all legs
- OI < 100 → −0.10 · OI < 500 → −0.05
score = base_score × skew_multiplier × tech_multiplier
Both multipliers are shown per spread. Beta is informational only — ATR already captures realized vol. Full algorithm documentation →

Dealer Positioning
LOW γ vs HISTORY
Estimated net dealer gamma is at the 2nd percentile of this name's own daily history, near the low end of its range. This describes current positioning; it is not a forecast or a trading signal.

δ-decay vs time
Vanna tilt +0.71: the estimated dealer exposure leans positive, so the modeled hedge would shift noticeably if implied volatility changed.
Charm tilt -0.77: the estimated dealer exposure leans negative, so the modeled hedge would shift noticeably as time passes and options approach expiry.
? What is this?
· 48 ATM contracts, 4k total OI
Net dealer gamma is an estimate of the aggregate gamma held by options market makers across this name's option chain, weighted by open interest. Dealer positions aren't public, so it uses a standard simplifying assumption: dealers are treated as long the calls and short the puts that are open. Actual dealer books can differ.
Gamma percentile ranks today's estimate against this name's own daily history, from 0% (the lowest reading on record) to 100% (the highest). Raw gamma scales with how much open interest a chain carries, so it isn't comparable across names; the percentile is. The badge marks the bottom 20% as low and the top 20% as high.
Tilts run from −1 to +1 and show how lopsided the estimated dealer exposure is. GEX tilt compares call gamma with put gamma. Vanna tilt describes how the hedge would shift if implied volatility changed, and charm tilt how it would shift with the passage of time.
This card describes estimated positioning and where it sits historically. It is not a forecast of price direction or volatility and not a trading signal. Market-wide view: Dealer positioning screener.
Skew (Wing IV − ATM IV)
DTE:
Wing Δ:
Wing vs ATM
IV(put wing) − IV(ATM), in vol pointsHow much the OTM put trades above (or below) the at-the-money strike. Measures the height of the put-side tail relative to ATM — i.e. how expensive crash insurance is on this name.
- Positive (typical) — wing IV > ATM IV. Standard equity put skew: portfolios bid up crash protection, so OTM puts trade richer than ATM.
- Near zero or negative (unusual) — wing IV ≤ ATM IV. Flat or inverted put side. Common when there's no fear demand, in tightly mean-reverting names, or right after an earnings catalyst clears.
- Percentile vs own 3-yr history: high = wings rich (good time to sell wing premium); low = wings cheap (good time to buy protection).
- Not directional — high or low wings don't predict up or down moves. It's a price tag on tail insurance, not a forecast.
Risk Reversal
IV(call wing) − IV(put wing), equal delta on each sideWhich side of the smile is the market paying up for? Measures the tilt of the surface — call skew vs put skew at matched deltas.
- Negative (typical) — puts richer than calls. Standard equity behavior: hedging demand makes puts carry a premium. Most large-caps sit in the −1 to −5 vol-point range.
- Strongly negative (< −5 pts) — heavy downside hedging, elevated fear, or an upcoming catalyst (earnings, FDA, macro event). Worth flagging.
- Positive — calls richer than puts. Unusual for equities; signals bullish momentum, short-squeeze positioning, or takeover/M&A speculation.
- Near zero — symmetric surface. Market sees roughly equal up/down risk. Rare for large-caps; more common in commodities and FX.
Reading them together
Wing-vs-ATM tells you how expensive the tails are. Risk Reversal tells you which side is favored. Combined:
- High wing percentile + deeply negative RR → strong put bid; stress or major event priced in. Owning protection costs a premium; selling put premium is dangerous.
- Low wing percentile + near-zero RR → complacency; insurance cheap and balanced. Good environment to add cheap downside hedges.
- Positive RR + elevated wings → call-side fear-of-missing-out; common in squeeze setups. Upside calls expensive, downside puts not bid.

Extreme reading.
Historically these have been contrarian — on the small set of observed earnings-day cases, large negative wing-vs-ATM gaps (calls pricing much richer than puts at the same delta) preceded sharp drops in the underlying within 1-12 days. Not financial advice and the dataset is small.
Percentile is the rank of today's reading within ~3 years of this symbol's own history. High percentile = wings are rich relative to history; not a directional signal. Skew is read off the chain in real time, not from CBOE SKEW.

Beta & Alpha Over Time
VOOG Institutional Ownership (13F)
Latest filings — 2026-09-30Institutional managers with $100M+ AUM file Form 13F-HR quarterly, due 45 days after quarter end. Holdings are reported gross at quarter-end market value — they are a snapshot, not a real-time position.
- Shares — long equity positions in this name, aggregated across share classes.
- Calls / Puts — notional value of long call / put exposure where this ticker is the underlying.
- % of Float — holder's reported shares divided by the latest diluted shares outstanding. Sums above 100% indicate large custodian / prime broker positions where the same shares are reported by multiple filers.
- Custodian badge — filers with more than 5,000 holdings are typically broker-dealers / custodians reporting customer-held shares, not active managers.
Each filer is counted once at its latest 13F-HR filing. New filings are ingested on a weekly cadence.

Short Interest & Float
Regulatory short-interest reports publish on a bi-weekly settlement cadence; short-volume is reported daily by the trade-reporting facilities. Float is derived from insider-ownership filings.
Metric definitions
- Short Interest — total shares currently sold short as of the settlement date. Lags real time by ~8 business days.
- SI % of Float — short interest / free float. The key crowding metric.
- Days to Cover — short interest / avg daily volume. How many full trading days it would take shorts to buy back. High DTC + catalyst = squeeze fuel.
- Short Vol Ratio — today's short-sale volume / total volume. Intraday selling pressure proxy (not the same as short interest).
- Free Float — shares available for public trading (total shares minus insider / restricted).
- Float % — free float / shares outstanding. <50% = tightly held, more prone to squeezes.
How to read the signals
- SI % of Float < 5% — typical, no particular signal.
- 5–15% — elevated; watch for catalysts (earnings, guidance, macro).
- 15–30% — heavily shorted; tight-float names in this range have produced notable squeezes historically.
- >30% — extreme; borrow is likely expensive and squeeze risk is material.
- Days to Cover > 5 combined with high SI% amplifies squeeze potential.
History chart
- Trend matters more than level. Rapidly rising short interest often precedes negative catalysts or heavy hedging.
- A sudden drop in SI after a rally may indicate a squeeze in progress.
Short interest is reported mid-month and end-of-month; short volume is daily.
