I've built a real-time triangular arbitrage detection system as my first Rust project and would love feedback from more experienced Rustaceans.
What it does: Connects to Kraken's WebSocket API, maintains live order books across 8 trading pairs using Arc<RwLock<T>>, and detects triangular arbitrage opportunities in real time, displaying everything via a ratatui TUI.
I'm particularly interested in feedback on:
Whether my Arc<RwLock<T>> usage and locking strategy is idiomatic
The task structure in main.rs — spawning three independent Tokio tasks and coordinating shutdown
Error handling with anyhow — is this appropriate, or should I be using typed errors?
Anything that feels un-idiomatic or that a Rust developer would raise an eyebrow at
