Wires the new dashboard to real market data and adds the strategy
builder & screener UIs that were stubbed in the previous commit.
Frontend (web/src/):
- lib/marketApi.ts: authenticated fetch helpers for chart bars,
market indices, news, and FMP research endpoints
- views/HomeView.tsx: StockChart now fetches live OHLCV via
fetchChartBars on symbol/period change with loading/error states;
ResearchCards replaces the static placeholder with live FMP
profile/metrics/earnings (next-earnings + last 3 historical)
- components/layout/Header.tsx: live SPY/DIA/QQQ price + change%
via fetchMarketIndices, refreshing every 60s; removed unused
static sparkline placeholder
- components/strategy/VisualRuleBuilder.tsx: drag-and-drop IF/THEN
rule composer using @dnd-kit (RSI/MACD/EMA/Price/Volume,
above/below/crosses, BUY/SELL with shares or % of capital);
saves via POST /api/profiles
- components/strategy/CodeStrategyEditor.tsx: Monaco editor with
JS strategy template; "Run Backtest" posts to /api/backtest and
renders return/win-rate/Sharpe/drawdown plus trade log
- views/ResearchView.tsx: adds "Visual Builder" and "Code Editor"
sub-tabs alongside Strategies / Signals / Backtesting
- views/ScreenerView.tsx: live FMP screener with market-cap and
sector filters, sortable columns, click-to-load-symbol routing
- index.css: light theme background; @keyframes spin for loaders
- App.dom.test.tsx: rewritten for router-based AppShell (was
asserting on the removed tab UI; fixes 5 prior failures)
Backend (backend/src/services/apiServer.ts):
- /api/chart/bars: detects crypto symbols (contains "/") and
routes to Alpaca v1beta3/crypto/us/bars; equities use
v2/stocks/{symbol}/bars with iex feed
- (existing) /api/news, /api/market/indices, /api/research/{
profile,metrics,earnings}, /api/screener proxy endpoints
Build/config:
- web/vite.config.ts: dedupe react / react/jsx-runtime /
react-router-dom so the vendored react-auth dist resolves the
same React instance (fixes "Cannot resolve react/jsx-runtime"
Rollup error)
- web/tsconfig.app.json: exclude shared/platform-clients.ts and
shared/platform-mobile.ts (mobile-only, missing RN SDK)
- web/package.json: add react-router-dom, @monaco-editor/react,
@dnd-kit/core, @dnd-kit/sortable, @dnd-kit/utilities
Verification: `npm run build` in web/ → clean (✓ built in 3s);
backend tsc --noEmit → clean. Test suite: 151/155 pass; the 4
remaining failures are pre-existing (3 useTabFeatureFlags module
cache leaks, 1 EntryForm), not introduced here.

Web:
- runtime.ts: use import.meta.env (process.env is undefined in Vite browser bundle)
- tradingApiUrl local fallback: drop /api suffix (API libs already append /api/*)
- useWebSocket: deriveSocketParams() — correctly splits origin + socket path for
Caddy handle_path /invttrdg/* proxy (io(origin, {path}), not io(url-with-path))
- App.tsx: pass socket prop to AdminTab; pass connected prop to SignalsTab
- AdminTab: remove duplicate useWebSocket; accept socket as prop
- SignalsTab: connection-aware empty state message
- backtest/flags: default to disabled when VITE_BACKTEST_ENABLED unset
- EntryForm: NaN guard before live trade execution
- MarketplaceTab: null-safety on symbols.rules access
- Tests: pass socket prop to AdminTab; update empty state assertion
Mobile:
- TradingDataProvider: same deriveSocketParams fix — EXPO_PUBLIC_SOCKET_PATH
overrides auto-derived path from tradingApiUrl
- strategies: replace mock data with real GET /api/profiles + PATCH active toggle
- chat: wire to real POST /api/chat; remove hardcoded mock reply
- marketplace: fetch GET /api/marketplace-presets; USE STRATEGY calls POST /api/profiles
- settings: sign-out confirmation dialog; execution mode read-only hint;
version from expo-constants instead of hardcoded v2.3
- positions/history: empty state UI when no data
- CustomTabBar: always show tab labels (not only when focused)
