}

The crate-wide error type.

Wraps all failure modes: network errors, JSON deserialization failures, WebSocket issues, auth errors, and TradingView-specific protocol errors.

Conversion

Common external errors (reqwest::Error, serde_json::Error, chrono::ParseError, etc.) convert automatically via From impls.
