Struct SessionStatus 

pub struct SessionStatus {

    pub id: String,
    pub finding: String,
    pub executor: String,
    pub instrument: String,
    pub strategy: String,
    pub started_at: String,
    pub state: String,
    pub signals: u32,
    pub submitted: u32,
    pub refused: u32,
    pub fills: u32,
    pub halted: Option<String>,
    pub last_error: Option<String>,
    pub last_bar: Option<String>,
    pub frozen: Option<String>,
    pub reconciled: bool,
    pub verdict: String,
    pub verdict_reason: Option<String>,
    pub warnings: Vec<String>,
    pub divergence: Option<Divergence>,
}

Every shape at the root as well, because a window names a view on nearly every line and arvo_api::research::StudyView would be noise. The names do not collide: proto has no overloading and neither does this.

Fields

id: String

finding: String

executor: String

instrument: String

strategy: String

started_at: String

state: String

starting, running, frozen, halted, stopped or failed.

signals: u32

submitted: u32

refused: u32

fills: u32

halted: Option<String>

Why the gate halted, when it did.

last_error: Option<String>

last_bar: Option<String>

frozen: Option<String>

What the gate and the venue disagreed about, while frozen (#187).

reconciled: bool

Whether a frozen session has been reconciled, so ResumeSession is allowed.

verdict: String

Whether the rule is still the rule its finding described: holding, diverging or inconclusive, judged from the session’s own trades against the finding’s out-of-sample expectation (#221). Never a risk limit.

verdict_reason: Option<String>

Why it is diverging, when it is: what was seen against what was expected.

warnings: Vec<String>

The gate’s limits this session is within four fifths of (#191), in the gate’s words: “drawdown 8.1% of a 10.0% limit”. Empty while halted.

divergence: Option<Divergence>

What the fills cost against the decision prices (#18): the divergence a paper session exists to measure. Absent until something filled.

pub fn frozen(&self) -> &str

Returns the value of frozen, or the default value if frozen is unset.

pub fn verdict_reason(&self) -> &str

Returns the value of verdict_reason, or the default value if verdict_reason is unset.
