## Key Concepts

### Hybrid Matching Algorithm

The trading analysis uses a hybrid matching system that combines broker-provided realized gains/losses with transaction history to achieve broker-level accuracy for closed positions. See [Hybrid Matching](/features/hybrid-matching) for details.

### Multi-User Support

The application supports multiple users with isolated data. Each user can have separate brokerage accounts and portfolios, with data access controlled by OAuth authentication.

### Real-Time Price Updates

Portfolio holdings are updated with real-time prices from Finnhub API, with intelligent rate limiting and caching to stay within API quotas while providing fresh data.
