//! Display group events example
//!
//! Display Groups are a TWS-only feature (not available in IB Gateway).
//! They allow organizing contracts into color-coded groups in the TWS UI.
//!
//! # Usage
//!
//! ```bash
//! cargo run --no-default-features --features sync --example group_events
//! ```
//!
//! Make sure TWS is running with API connections enabled
