//! Bybit Integration Tests
//!
//! These tests verify the Bybit exchange implementation against the real API.
//! They can be run with: cargo test --test bybit_integration_test
//!
//! Note: Tests are marked with #[ignore] to avoid hitting API rate limits
//! during normal test runs. Run them explicitly with:
//! cargo test --test bybit_integration_test -- --ignored
//!
//! _Requirements: 4.1, 4.3, 5.1_
