IV Spike Scanner
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.

IV Spike Scanner
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.
