Struct MaxConsecutiveLossRule 

pub struct MaxConsecutiveLossRule {
    pub max_consecutive: usize,
    /* private fields */
}

Triggers a breach when equity has declined for max_consecutive consecutive updates.

Each call to RiskMonitor::update where equity is lower than the previous update counts as a loss. When the streak reaches max_consecutive, a breach is returned for every subsequent declining update until the streak resets.

Because this rule must track state across calls, it holds a mutable counter internally using std::cell::Cell.

Fields

max_consecutive: usize

Maximum number of consecutive declining equity updates before breach.
