Struct LedgerTrade 

pub struct LedgerTrade {

    pub instrument: String,
    pub opened: String,
    pub closed: String,
    pub direction: String,
    pub quantity: f64,
    pub entry: f64,
    pub exit: Option<f64>,
    pub pnl: f64,
    pub commission: f64,
    pub exit_reason: String,
    pub rule: Option<String>,
    pub signal: Option<f64>,
    pub regime: Option<String>,
    pub asked: Option<f64>,
}

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. One trade in a ledger: a round trip, or a position still open at the end (empty closed, no exit).

Fields

instrument: String

SYMBOL.VENUE; empty when it is the experiment’s own instrument.

opened: String

closed: String

direction: String

“long” or “short”; empty means long.

quantity: f64

entry: f64

exit: Option<f64>

pnl: f64

commission: f64

exit_reason: String

“signal”, “stop”, “halted”, “expired” or “still_open”; empty means signal.

rule: Option<String>

What the rule saw at entry (#190): the condition that fired, the value it was judged on, the regime it saw, and the quantity it asked the gate for. Absent on a trade recorded before the journal or opened by no rule.

signal: Option<f64>

regime: Option<String>

asked: Option<f64>
