Each spoke is this symbol's rank within its sector (0–100; the dotted ring marks the sector median at 50). Higher is more constructive for a long. One spoke — News sentiment — is an absolute reading, not a sector rank. Grayed spokes have no data. A fuller shape is a summary, not a recommendation.
Quick-reference for reading the values below. Indicators combine to confirm a view — no single one is a trade signal on its own.
- 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.
- 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.
- 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 →

Each spread is ranked by a composite score built in three stages. Full documentation →
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.
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.
- RSI <40 bullish / >60 bearish
- MACD crossover + histogram trend
- Price vs SMA 50 & SMA 200
- Stochastic %K <20 / >80
- Williams %R <−80 / >−20
- Blended ATR + straddle expected-move penalty
- Bollinger Band signal (+ counter-trend penalty)
- BB width — vol contraction boost for ICs
- IV rank ≥ 75 → strong boost for credit spreads
- IV rank < 25 → penalty (selling cheap vol)
- 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 →

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.
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.
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.
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.

- 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.

What is Form 144? A notice of intent to sell restricted or control stock under Rule 144. Affiliates (officers, directors, 10%+ owners) and holders of restricted shares must file Form 144 when planning to sell more than 5,000 shares or $50,000 in any 3-month rolling window.
How it relates to Form 4: Form 144 is filed before the trade (up to 90 days in advance); Form 4 is filed within 2 business days after the trade executes. Not every Form 144 results in a sale — the filer may cancel or delay. Look for the corresponding Form 4 on the Insider Activity card to confirm a sale actually happened.
10b5-1 plans: Trades made under a pre-scheduled Rule 10b5-1 plan are not discretionary — they execute automatically on dates set months earlier, regardless of news. High 10b5-1 percentages mean less per-filing signal value, though cumulative selling volume still matters.
"Notice value": Aggregate market value the filer wrote into the Form 144 — i.e. the size of the planned sale, not necessarily the executed dollars. Amendments (Form 144/A) and post-cancellation refilings can inflate this if you sum naively; the rollup above excludes filings with zero stated value.
Source & freshness: Sourced from public Form 144 filings. Refreshed daily; new filings typically appear here the morning after they are filed.

Quarterly filings sourced from SEC 10-Q / 10-K reports. TTM tiles aggregate the most recent four quarters; bars show the last ~12 quarters oldest → newest.
- Revenue — top-line sales. Look for consistent YoY growth; seasonal businesses need same-quarter comparisons (Q4 '24 vs Q4 '23).
- Net Income — bottom-line profit after all expenses. Can be volatile from one-time items; red bars = net loss.
- Diluted EPS — net income per share assuming options/converts are exercised. Direct input to the P/E ratio.
- Operating Cash Flow — cash generated from core operations, before capex and financing. Harder to manipulate than net income; growing OCF is a quality signal.
- Sequential growth — quarter-over-quarter trend. Accelerating bars are a momentum signal.
- YoY growth — compare to the same quarter a year earlier to remove seasonality.
- Quality — OCF should roughly track Net Income over time. Large divergence (net income ≫ OCF) flags accruals risk.
- Margins — scan the bar ratios: Net Income / Revenue tells you margin trend without needing a separate chart.
TTM (trailing-twelve-month) smooths seasonality and is used for the P/E calculation. Filings appear 30–90 days after the period closes.
