    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 held_days: Option<f64>,

}

One round trip, as a table row.

Every field the ledger holds, because the point of a table is that nobody has to decide in advance which column someone will want to sort by. The aggregate statistics above it answer “how did it do”; this answers “what did it actually do”, and those are different questions with different failure modes — an expectancy of +£300 built from one +£9,000 trade and nineteen losses is a fact only the rows show.

Fields

instrument: String

Which instrument this round trip was in.

Empty for a run recorded before the ledger named instruments, and for an ordinary single-instrument study where the subject line already says it. Only a book shows the column.

opened: String

closed: String

Empty while the position is still open at the end of the run.

direction: String

quantity: f64

entry: f64

exit: Option<f64>

None while still open, so the table shows a gap rather than a price nobody traded at.

pnl: f64

commission: f64

held_days: Option<f64>

Days held. Fractional, because an intraday trade held forty minutes is not “0 days” — it is 0.03, and rounding it away would make every intraday ledger look like a column of zeroes.

exit_reason: String

signal, stop, or open.

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>
