Struct PositionClose 

pub struct PositionClose {
    pub symbol: String,
    pub side: Side,
    pub qty: f64,
    pub entry_price: f64,
    pub exit_price: f64,
    pub pnl_realized: f64,
    pub rr_ratio: Option<f64>,
    pub strategy: Option<String>,
    pub position_id: Option<String>,
    pub session_id: Option<String>,
}

A terminal event: the producer closed a position. Carries the realized outcome so Janus can record what actually happened against the guidance it advised while the position was open. Sent to POST /api/v1/positions/close.

Fields

symbol: String

Trading pair / instrument (e.g. “BTC-USD”).

side: Side

Direction the (now-closed) position was held in.

qty: f64

Position size in base units (always positive).

entry_price: f64

Average fill price the position was opened at.

exit_price: f64

Average fill price the position was closed at.

pnl_realized: f64

Realized P&L in quote currency (signed).

rr_ratio: Option<f64>

Optional realized risk-reward ratio for this trade, when the producer tracks it. Fed straight into affinity learning.

strategy: Option<String>

Optional strategy name that opened this position. Required for the outcome to be fed back into the per-(strategy, asset) affinity tracker; omitted closes are still persisted, just not recorded live.

position_id: Option<String>

Client position id, used to correlate with the open snapshots so the outcome can be joined with this position’s guidance history.

session_id: Option<String>

Optional JanusAI session id.

Implementations

impl PositionClose

pub fn validate(&self) -> Result<(), &'static str>

Reject malformed close events at the boundary.

pub fn realized_ratio(&self) -> Option<f64>

Realized P&L as a ratio of entry notional. None when notional is non-positive (impossible after validate).
