#![allow(clippy::uninlined_format_args)]
//! Async historical tick data example
//!
//! This example demonstrates how to request historical tick-level data using the async API.
//! This includes trades, bid/ask quotes, and midpoint data.
//!
//! # Usage
//!
//! Make sure IB Gateway or TWS is running with API connections enabled, then run:
//!
//! ```bash
//! cargo run --features async --example async_historical_ticks
//! ```
//!
//! # Configuration
//!
//! - Adjust the connection address if needed (default: 127.0.0.1:4002)
//! - Change the stock symbol if desired (default: AAPL)
//! - Modify start/end times or number of ticks
