Struct TrailingConfig 

pub struct TrailingConfig {
    pub arm_ratio: f64,
    pub giveback_frac: f64,
    pub ttl: Duration,
    pub max_entries: usize,
}

Tunables for the stateful guidance layer in PositionTracker.

Fields

arm_ratio: f64

Peak gain (ratio of notional) a position must reach before the trailing give-back rule arms. Peaks below this are too small to act on.

giveback_frac: f64

Fraction of the peak gain that, once surrendered, triggers a Reduce to lock in what’s left. 0.5 ⇒ “gave back half the peak”.

ttl: Duration

Evict positions not seen within this window (presumed closed/stale).

max_entries: usize

Hard cap on tracked positions, so a misbehaving producer can’t grow the map without bound.
