Summary

Improve perceived data loading performance when entering app pages, especially the Trading page, so recently loaded data is reused immediately instead of making the user wait on every navigation.

Plan saved at: .hermes/plans/2026-06-17_005055-improve-page-data-loading.md

Final plan

See .hermes/plans/2026-06-17_005055-improve-page-data-loading.md in the repository for the full implementation plan.

Implementation checklist

Add centralized TanStack Query client defaults in the web app.
Tune Trading page query options for positions and trade automation data.
Preserve the 15s positions refresh while Trading is mounted.
Ensure open/close/mode mutations still invalidate affected queries.
Add or update tests for query-client defaults and/or Trading query behavior.
Run pnpm test.
Run pnpm typecheck.
Optionally verify route re-entry behavior manually with the web app/network panel.

Acceptance criteria

Returning to Trading within the cache window renders last loaded positions/automation data immediately.
Trading data still refreshes approximately every 15 seconds while the page is open.
Mutations still refresh affected data after success.
Existing alert, scanner, and navigation behavior remains unchanged except for improved cache reuse.
Tests and typecheck pass.

Test plan

pnpm test
pnpm typecheck
Manual validation if practical: first Trading visit fetches data; leaving and returning shortly after shows cached data immediately; periodic refetch still happens while open.

Notes

Implementation is gated by applying the ready-for-dev label. Hermes will monitor this issue and start implementation automatically after that label is added.
