Alpaca API Integration - Dual Account Setup

Implementation

Hedge supports both Paper and Live Alpaca trading accounts with separate credentials.

Environment Variables

# Paper Account
ALPACA_PAPER_API_KEY=xxx
ALPACA_PAPER_SECRET_KEY=xxx

# Live Account  
ALPACA_LIVE_API_KEY=xxx
ALPACA_LIVE_SECRET_KEY=xxx

AlpacaClientManager

Singleton that manages both clients:

• get_client(account_type) → Returns Paper or Live client
• Auto-switches based on request parameter

Services

• TradingService: Submit orders, get positions
• MarketDataService: Real-time quotes, historical bars
• NewsService: Market news feed

Tested & Working

• Both accounts authenticate successfully
• Market data streaming works
• Account info retrieval works

Security Note

Henry explicitly requested: NEVER display live Alpaca API keys in logs, UI, or responses. Paper keys OK for debugging.
