eExchange — the trading app
The exchange's member-facing trading app: order entry tickets, the working blotter, market-data watchlists, account positions, and executions — for desk operators and authorized member users, through the BFF proxy like every platform app.
What it demonstrates
- Thin by design — no FIX stack in the app: order entry rides the BFF-proxied REST/WebSocket shapes Gateway serves; the token never reaches the client bundle.
- Live authorization — a member user's tradable symbols and order types derive from live Shield decisions, not embedded claims.
- Real-time surfaces — market data over SSE, blotter updates over the subscription tier, positions from the clearing ledger.
