Struct PositionState

pub struct PositionState {
    pub first_seen: Instant,
    pub last_seen: Instant,
    pub samples: u64,
    pub peak_pnl_ratio: f64,
    pub last_action: GuidanceAction,
}

Expand description

Rolling per-position state, accumulated across the repeated snapshots a producer pushes for the same position_id. Lets guidance depend on a position’s history (peak profit, prior advice) rather than scoring each snapshot in isolation.

Fields§

§first_seen: Instant

Instant the first snapshot for this position arrived.

§last_seen: Instant

Instant the most recent snapshot arrived (drives TTL eviction).

§samples: u64

Number of snapshots observed for this position.

§peak_pnl_ratio: f64

Highest unrealized-P&L ratio (pnl / notional) seen so far.

§last_action: GuidanceAction

Most recent guidance action issued for this position.
