Stock Trading Platform Deployment
How a broker's trading platform is deployed for low latency: co-located order gateways near the exchange, and cloud services for apps and back office.
Deployment diagrams are part of Pro. Anyone can view this one; generating and editing it needs Pro.

What this diagram shows
- Order management and exchange gateways are co-located at the exchange
- Market data is streamed to apps over WebSockets
- Risk checks run before every order leaves the broker
Prompt used
Deployment of a stock broking platform: traders use web and mobile apps that connect to cloud-hosted API and WebSocket servers. Orders go over a leased line to the co-location rack at the exchange data centre, where the order management system runs pre-trade risk checks and sends orders through exchange gateways (NSE, BSE). Market data feed handlers in co-location stream prices back. Back office (contract notes, ledger) runs in the cloud with PostgreSQL.
