 _A sanitized data-engineering case study demonstrating a real-time FX streaming pipeline on GCP._
 
+> **What is “BARX-style”?** A reference to a well-known FX trading platform at a Tier-1 UK bank.  
+> This repo **simulates** those event-stream patterns (quotes, trades, fills/confirmations).  
+> **No client code or data.**

 > **Quick Facts**  
-> **Use-case:** real-time FX trades/quotes → enriched → analytics  
+> **Use-case:** real-time **BARX-style** FX quotes/trades/confirmations → enrichment → analytics
+> **Events:** quotes, trades, fills/confirmations; exactly-once via insertId; late data via watermarks  
 > **Stack:** GCP (Pub/Sub → Dataflow/Beam → BigQuery) + Composer; VPC-SC, CMEK  
 > **Throughput:** ~6–7 M events/day (~250–400 events/sec); E2E p95 < 90 s  
 > **Patterns-only:** no client code/data; fully sanitized
