Methodology

The system was developed using modern web technologies:

• Frontend: Next.js 15 with TypeScript for type-safe, performant UI
• Backend: Next.js API routes with custom trading engine
• Real-time Communication: Server-Sent Events (SSE) with PostgreSQL NOTIFY/LISTEN
• Data Persistence: PostgreSQL via Supabase with advanced security policies
