Hi HN!

I built OXH AI - an AI-powered cryptocurrency signal platform that generates real-time trading signals using technical analysis and machine learning.

What it does: - Generates AI trading signals for 100+ crypto pairs (Bitcoin, Ethereum, etc.) - Real-time technical indicator analysis (RSI, MACD, Bollinger Bands, EMA) - Risk scoring and position management - Auto-backtesting with historical data - Live chart integration with TradingView-style interface

Why I built this: Most crypto signal platforms are either: 1. Black boxes with no transparency 2. Manual signals from "gurus" (often wrong) 3. Expensive ($100-500/month)

I wanted something transparent, AI-driven, and affordable.

Tech Stack: - Frontend: React + TypeScript + Vite - Backend: Node.js + Express + TypeScript - Database: Supabase (PostgreSQL) - AI: OpenAI GPT-4 for market analysis - Real-time: WebSocket for live updates - APIs: Binance, Bybit, OKX for price data

Interesting Technical Challenges: 1. Race Condition Prevention: Implemented optimistic locking for Telegram auto-posting to prevent duplicate messages 2. Schema.org Optimization: Added LocalBusiness + Organization markup for better Google indexing 3. Rate Limiting: Built custom rate limiter that handles 50K+ API calls/day 4. Real-time Updates: WebSocket connections for live price & signal updates

Features: - Free tier: 5 signals/day (no credit card) - Paid tier: Unlimited signals + advanced analytics - Referral system with leaderboard - Blog with auto-generated crypto content (2x daily) - Crypto news aggregation (updates every 2 hours)

Privacy & Security: - No trading API keys stored (non-custodial) - Read-only market data - 2FA/MFA support - GDPR compliant

What's Next: - Mobile app (React Native) - More exchanges (Kraken, Coinbase) - Advanced AI models (custom-trained on crypto data) - Social trading features
