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
Full Algorithm Docs ↗

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 →

Skew (Wing IV − ATM IV)
DTE:
Wing Δ:
Metric:
Wing vs ATM
IV(put wing) − IV(ATM), in vol points

How 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 side

Which 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.

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.

GRN Institutional Ownership (13F)

Latest filings — 2026-06-30

Institutional 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.
