//! Barrier Parameter Optimizer Example
|
||||
//!
|
||||
//! Uses Monte-Carlo simulations to find optimal triple-barrier parameters
|
||||
//! for ES.FUT, NQ.FUT, ZN.FUT, and 6E.FUT futures contracts.
|
||||
//!
|
||||
//! ## Usage
|
||||
//! ```bash
|
||||
//! cargo run -p ml --example optimize_barriers --release
|
||||
//! ```
|
||||
//!
|
||||
//! ## Expected Output
|
||||
//! - Optimal profit_target_bps, stop_loss_bps, max_holding_period
|
||||
//! - Sharpe ratio, win rate, max drawdown for each configuration
|
||||
//! - CSV file with full grid search results
