Purpose and entry points

IntraTrade is a real-time NSE intraday signal dashboard. The React SPA starts at ORB Strategy/dashboard/src/index.js and composes its UI in ORB Strategy/dashboard/src/App.js. The Node service starts from ORB Strategy/server/index.js, exposing REST APIs and a Socket.IO signal stream.

Frontend application

The dashboard presents market-open/closed state, Kite authentication callback flow, strategy selection, and live stock signals. Primary views/components are under:

• ORB Strategy/dashboard/src/components/home.js

• ORB Strategy/dashboard/src/components/stocks.js

• ORB Strategy/dashboard/src/components/KiteCallback.js

The browser calls /api/* for session, algorithm, watchlist, and market-status operations, then consumes Socket.IO broadcasts for incremental signal updates.

API and session boundary

Express routing separates API endpoints from engine orchestration:

• ORB Strategy/server/routes/index.js

• ORB Strategy/server/routes/api.js

• ORB Strategy/server/controllers/method.js

The controller is the integration boundary for Zerodha Kite Connect: it establishes/authenticates Kite access, obtains market status, manages subscriptions, and coordinates the ticker lifecycle with Socket.IO clients.

Streaming signal engine

KiteTicker delivers full-mode ticks for the selected NSE watchlist. On each tick, the engine retains instrument-specific state, invokes the active strategy, filters actionable Buy/Sell results, and broadcasts the resulting signal set. The strategy registry enables live switching without restarting the market stream:

• ORB Strategy/server/controllers/method.js

• ORB Strategy/server/algos/index.js

• ORB Strategy/server/data/nse_symbols.js

nse_symbols.js supplies the Nifty 50/100/500 subscription universes; environment configuration determines the active list and strategy thresholds.

Quantitative strategy boundary

Strategies are independent stateful-per-instrument calculation modules behind a common algorithm interface:

• ORB Strategy/server/algos/orb.js

• ORB Strategy/server/algos/vwap.js

• ORB Strategy/server/algos/momentum.js

• ORB Strategy/server/algos/ema.js

ORB captures an opening price range; VWAP and momentum compare LTP against intraday references; EMA detects crossover events. Each generates direction and stop-loss values, while the controller owns tick transport, strategy selection, and client broadcast.

Runtime and deployment

The system runs Node.js/Express plus Socket.IO and a separately built React static site. Docker builds the SPA into nginx and packages the backend:

• ORB Strategy/dashboard/Dockerfile

• ORB Strategy/dashboard/nginx.conf

• ORB Strategy/server/Dockerfile

• docker-compose.yml

Production traffic is intended to pass through Traefik with TLS: SPA requests go to nginx, /api and health traffic to Express, and /socket.io to the realtime server. Zerodha Kite Connect is the external market-data and authentication dependency.

Delivery boundary

GitHub Actions deploys the repository to a remote Docker Compose host:

• .github/workflows/deploy.yml

• .env.production.example

Secrets, Kite credentials, domain configuration, market hours, watchlist size, and strategy parameters are runtime/deployment concerns rather than application source state.
