//! Wave Comparison Backtesting Example
|
||||
//!
|
||||
//! This example demonstrates how to run comprehensive backtesting to validate
|
||||
//! performance improvements across Wave A, Wave B, and Wave C.
|
||||
//!
|
||||
//! Usage:
|
||||
//! ```bash
|
||||
//! cargo run -p backtesting_service --example wave_comparison
|
||||
//! ```
|
||||
//!
|

//! Expected Output:
|
||||
//! - Console summary with detailed metrics
|
||||
//! - JSON export: results/wave_comparison_ES.FUT_YYYYMMDD_HHMMSS.json
|
||||
//! - CSV export: results/wave_comparison_ES.FUT_YYYYMMDD_HHMMSS.csv
