- frontend.py: /book was calling /book on matcher (404); fixed to
/orderbook/<symbol> with ?symbol= query param
- Order Entry: pass selected symbol to /book, reload on symbol change
- Order Entry: add ← Dashboard link via onclick (not href)
- FIX UI: ← Dashboard href="/" was rewritten by nginx sub_filter to
/fix/; fixed by switching to onclick so sub_filter can't touch it

Frontend (disconnected root cause):
- All fetch('/endpoint') calls were hitting nginx '/' (dashboard) instead
of '/frontend/endpoint'. Added BASE detection at page load:
const BASE = window.location.pathname === '/' ? '' : pathname.replace(/\/$/, '');
Applied to /securities, /order, /book, /trades
FIX UI (session disrupted by reloader):
- debug=True caused Flask reloader to spawn a child process and restart
the app, breaking the QuickFIX session on startup
- Changed to debug=False, use_reloader=False
Entrypoint timing:
- FIX OEG sleep increased from 3s → 6s (allow full socket bind)
- FIX UI sleep increased from 2s → 3s (allow QuickFIX initiator to start)
Dashboard:
- Local clock added to header bar (updates every second, browser timezone)
