Struct MaxLossFromInitialRule 

pub struct MaxLossFromInitialRule {
    pub max_loss_pct: Decimal,
    pub initial_equity: Decimal,
}

Triggers a breach when equity has fallen by more than max_loss_pct from its initial value.

Unlike MaxDrawdownRule (which measures from the rolling peak), this rule measures from a fixed starting equity — useful for absolute loss limits on a session or account.

Fields

max_loss_pct: Decimal

Maximum allowable loss percentage from initial_equity (e.g. dec!(5) = 5%).

initial_equity: Decimal

The equity baseline this rule compares against.
