//! Example demonstrating live data testing with the Polymarket adapter.
//!
//! Connects to Polymarket via WebSocket, loads the configured event's
//! instruments from the Gamma API, then subscribes to trade ticks for the
//! selected market tokens.
//!
//! Edit the constants below to change the target event and market tokens.
//!
//! Run with: `cargo run --example polymarket-data-tester --package nautilus-polymarket --features examples`
//!
//! Credentials are read from the environment when set:
//! - `POLYMARKET_API_KEY`.
//! - `POLYMARKET_API_SECRET`.
