Enum Phase 

pub enum Phase {
    Observation,
    Decision,
    RiskEvaluation {
        passed: bool,
    },
    Submission {
        order: OrderId,
    },
    Acknowledgment {
        order: OrderId,
    },
    AcknowledgmentUnobserved {
        order: OrderId,
    },
    Fill {
        order: OrderId,
    },
    Reconciliation {
        order: OrderId,
    },
}

One stage of the trading lifecycle.

The intended order is observation, decision, risk evaluation, submission, acknowledgment, fill, reconciliation. The first three are per-subject; the last four are per-order and also carry the subject, so a drifting subject mid-order is detectable.

Variants

Observation

Market state was read for this subject.

Decision

A trading intent was formed for this subject.

RiskEvaluation

The pre-trade risk check ran for this subject. Only passed = true authorizes a later submission, and only for this subject.

Fields

passed: bool

Submission

An order was sent to the venue.

Fields

order: OrderId

Acknowledgment

The venue acknowledged the order.

Fields

order: OrderId

AcknowledgmentUnobserved

The submission was sent and its acknowledgment was not observed, so the write’s outcome is unknown: the venue may have committed it. This is a recorded fact about the trace, not an inference from elapsed time — the kernel has no clock, and silence of any duration is not evidence. It advances no stage; a later Phase::Acknowledgment for the same order resolves it.

Fields

order: OrderId

Fill

The order filled, in whole or in part.

Fields

order: OrderId

Reconciliation

The fill was reconciled against the position book.

Fields

order: OrderId
