The Premium Backtesting panel (internal id stock-backtest) renders a compact list of backtested results — one row per ticker — showing how previous Stock Analysis signals fared over their horizon. It’s the longitudinal complement to Premium Stock Analysis’s point-in-time view.

​
What the panel shows

A list of StockBacktestResult[] rows — one per symbol. Each row shows the ticker and percent-change / return figures formatted via fmtPct(), with positive values rendered in a bullish tint (#8df0b2) and negative values in a bearish tint (#ff8c8c) via tone(). Source state is tracked — 'live' | 'cached' — so the panel’s data badge shows whether the render came from a fresh fetch or a cached snapshot. Empty result sets render a “No stock backtests available yet.” retry state via showRetrying(). Panel id is stock-backtest; canonical component is src/components/StockBacktestPanel.ts. Title “Premium Backtesting” per the panel’s super({...}) call.

​
How you reach it

  • Cmd+K: type backtest or backtesting.
  • Availability by variant: registered and enabled by default in the full/geopolitical and finance variants — locked in both. Not present in the tech, commodity, or happy variants. Source: 'stock-backtest' entries in FULL_PANELS (:50) and FINANCE_PANELS.

​
Data sources

Backtests are produced by a Railway cron that replays previous analysis signals against historical price series. Results are stored in the premium-stock store and fetched via @/services/stock-backtest. The panel consumes StockBacktestResult[] through renderBacktests(items, source).

​
Refresh cadence

Backtest results update with the premium-stock cron. Freshness is signalled by the data badge (live vs cached).

​
Tier & gating

PRO (hard-locked). premium: 'locked' in the panel’s constructor and in variant registrations. isPanelEntitled unlocks it when either a valid WORLDMONITOR_API_KEY is present or isPro is true (stock-backtest is in the apiKeyPanels allowlist at src/config/panels.ts:973).
