The previous default leaned heavily on mega-cap tech. EDGE setups
are rarer than that — you want a wider net across sectors to catch
the 1-3 setups per week that actually qualify. Curated to 37 names
that are all optionable mid+ cap with reasonable LEAPS liquidity:
Indices/ETFs: SPY, QQQ, IWM, DIA, SMH, XLF, XLE, XLK
Mega-cap tech: AAPL, MSFT, NVDA, GOOGL, META, AMZN
Semis: AMD, INTC, TSM, AVGO, MU
High-vol/event-driven: TSLA, NFLX, COIN, PLTR, SHOP, UBER, MARA
Financials: JPM, BAC, GS, V
Healthcare: LLY, JNJ, UNH
Consumer/energy: XOM, WMT, DIS, MCD
Also bumped the per-scan cap from 30 to 100 so users can paste
custom lists up to 100 symbols (the previous 30-cap silently
truncated lists like the new 37-name default).
Full default scan completes in ~3.5s with zero errors and correctly
surfaces only the genuine EDGE setups (live test: NVDA / INTC / AAPL
flag, the other 34 do not).

User clarified the real entry signal: not just high IV, but IV
higher than HV — that's what makes premium "rich" relative to
realized vol and gives the mean-reversion edge for premium sellers.
Changes:
- New IV/HV column (was already computed server-side as r.ivHv but
not displayed). Colored cheap/fair/rich/very-rich. Sortable.
- New EDGE composite badge in the Flags cell: lights green when
IV Rank ≥ 60 AND IV/HV ≥ 1.20 — premium expensive in own history
AND not justified by what stock is actually doing.
- Summary row gains an "EDGE setups" count card.
- Page header copy reworked to explain the three richness signals
(IV Δ%, IV Rank, IV/HV) and why the composite EDGE flag matters.
Live test confirms the discrimination: INTC / AAPL / NVDA flag as
EDGE; TSLA (high IV/HV but low Rank — its normal regime) and SPY /
COIN (IV/HV high because realized vol is unusually quiet, not
because IV is rich) are correctly excluded.

IV Rank shows where current ATM IV sits in its 1-year (min, max)
range from saved snapshot history. The industry-standard entry
metric: >=60 = expensive (sell premium), <=30 = cheap (buy
premium). Also exposes IV Percentile (share of past snapshots
with strictly lower IV) via the tooltip.
- snapshots.ts: new getIvRange + getIvPercentile queries with
a min-samples gate so the metric is hidden until n>=5
- datafetch.ts: ScanResult gains ivRank, ivPercentile, ivRankN,
ivRankSpanDays
- options.ts: error stub updated with new fields
- scanner.html: new sortable IV Rank column with chip-styled
color coding (green/grey/yellow/red); summary row gains a
"High IV Rank (>=60)" count card; header text explains the
new metric and the >=60 / <=30 entry rule of thumb
Live INTC scan: IV Rank 100 (1-year peak) confirms the position's
short-premium structure was entered into expensive vol -
mean-reversion tailwind is the edge.

New /movers page surfaces Yahoo Finance's predefined screeners
(day_gainers, day_losers, most_actives, most_shorted_stocks)
filtered to common equities with market cap >= $2B, so every
listed name has a deep options chain. Per-row actions jump
straight into Chain / Vol Surface / IV Spike Scanner, or pin
the symbol to the Tracker watchlist.
- datafetch.ts: fetchMovers(category, count) using yf.screener,
post-filtered to quoteType=EQUITY and marketCap >= $2B
- options.ts: GET /api/movers?category=&count=
- movers.html: Tabler page with 4-tab segmented control, sortable
table, summary cards, volume-vs-avg ratio highlighting hot names
- All page sidebars: insert "Movers" link between Vol Surface
and Scanner

Replaces the IV/HV >= 1.5 heuristic with a baseline-relative jump:
a symbol is flagged SPIKE when current ATM IV is at least 30%
above its recent baseline (e.g., 10% -> 13%+). Baseline prefers
the 30-day average of saved snapshots; falls back to HV30 when
no scan history exists. Each scan persists a snapshot so the
baseline self-improves over time. BIG MOVE (|chg%| >= 3%) is now
shown as a separate badge instead of a spike requirement.
- snapshots.ts: add getAverageAtmIv(symbol, days)
- datafetch.ts: save snapshot per scan; compute baselineIv,
baselineSrc, baselineN, ivJumpPct; spike from jump threshold
- options.ts: /api/scan returns new baseline + jump fields
- scanner.html: header copy, table columns (Baseline IV, IV Δ%),
default sort by ivJumpPct desc, separate SPIKE/BIG MOVE badges

Backend: GET /api/scan?symbols=SYM1,SYM2,... — for each symbol fetches
the front-expiry options chain plus 30-day realized vol and returns
{ spot, change, changePct, atmIv, hv30, ivHv, spike, expiry }. Spike flag
is on when IV/HV ≥ 1.5 or |today's % change| ≥ 3. Defaults to ~15 popular
tickers when no list is given; cap of 30 symbols/scan.
Frontend: new scanner.html page — symbol input (with "Use defaults" / "Use
watchlist" shortcuts), summary cards (count · spikes · biggest mover ·
highest IV/HV), sortable results table with spike rows highlighted, and
shortcut buttons to open each symbol on Chain or Surface.
Scanner added to all sidebars between Vol Surface and Strategy P/L.
