Struct BacktestComparison 

pub struct BacktestComparison { /* private fields */ }

Builder that accumulates BacktestResults and ranks them.

Ordering

Call ranked_by to produce a ComparisonReport sorted best-first by the chosen OptimizeMetric.

Implementations

impl BacktestComparison

pub fn new() -> Self

Create an empty comparison.

pub fn add(self, label: impl Into<String>, result: BacktestResult) -> Self

Add a labelled backtest result.

The label is an arbitrary human-readable name (e.g. "SMA 10/50"). It does not have to match the strategy’s internal name.

pub fn ranked_by(self, metric: OptimizeMetric) -> ComparisonReport

Rank all added results by metric and return a ComparisonReport.

Results are sorted best-first (highest score wins for all metrics except OptimizeMetric::MinDrawdown, which is already negated internally so that a lower drawdown yields a higher score).

Trait Implementations

impl Debug for BacktestComparison

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BacktestComparison

fn default() -> BacktestComparison

Returns the “default value” for a type.
