DSR TradingView Alert Relay

DSR TradingView Alert Relay is a self-hosted TypeScript service that receives TradingView JSON alerts on a public webhook and routes them to Telegram and/or WhatsApp with normalized fields, position-size math, and structured logs. Built for disciplined traders who want a clean signal pipeline they own end-to-end. Runs anywhere Docker runs (VPS, Fly, Railway, Render, home lab). One-time license — no monthly relay fees. Highlights • Constant-time shared-secret verification (JSON body or secret URL path — TradingView does not send an HMAC header). • Optional per-IP allowlist, per-IP rate limiting, 32 KiB body cap, Zod schema validation. • Position-size engine: fixed risk amount OR account balance × risk percent, with a hard MAX_RISK_PER_TRADE cap and directional stop-side sanity checks. • Delivery adapters: Telegram (implemented), WhatsApp Cloud API (implemented, env-gated), Console (local demo). • Idempotency by alert_id, retry with exponential backoff, SQLite persistence, health endpoint, secret-redacting structured logs. • English + Arabic (RTL-safe) message templates. • Docker + docker-compose, .env.example, README, SETUP guide, SECURITY.md, LICENSE, example TradingView payloads, and unit + integration tests (Node built-in test runner + Fastify inject). Educational only — no broker integration, no order routing, no profit or accuracy claims. Use for alert routing and risk-sizing discipline; always validate on paper before live capital.
