System Components
REST Entry Gateways
- Requests are routed through Cloudflare.
- Requests are processed on a FIFO basis with no queuing.
- REST requires additional authentication because it’s stateless (as opposed to FIX order gateways, which authenticate during login).
FIX Order Gateways
- Each instance contains a per-user product based queue.
- Each per-user product-based queue can hold a maximum of 50 queued requests before requests are rejected.
- Each per-user product-based queue is processed on a FIFO basis.
Order Entry Gateway (Risk System)
- Each instance processes requests from FIX Order Gateways and REST in real time with no queuing.
- System performs real-time risk checks and account collateralization.
Trade Engine
- Clustered service that guarantees FIFO sequencing at a product level.
- Processes all requests from Order Entry Gateway.
- Publishes market data to WebSocket / FIX Market Data.
Market Data (Websocket & FIX)
- Each instance can process all market data requests across all products.
- Messages are distributed to customers randomly, and there is no intended benefit to being “first to subscribe”.
