Struct EquityGainTargetRule 

pub struct EquityGainTargetRule {
    pub target_pct: Decimal,
    pub initial_equity: Decimal,
}

Triggers a breach when equity has grown by more than target_pct from its initial value.

Useful as an automated profit-target alert: once equity has gained X%, the monitor signals the rule so the caller can decide whether to reduce risk or lock in gains.

Fields

target_pct: Decimal

The profit-target percentage gain from initial_equity (e.g. dec!(20) = 20%).

initial_equity: Decimal

The equity at the time this rule was created.
