Struct QuoteView 

pub struct QuoteView {
    pub instrument: String,
    pub symbol: String,
    pub price: Option<f64>,
    pub change: Option<f64>,
    pub held: bool,
}

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 row of the watchlist: an instrument, priced now.

held is why this is not just a ticker — the same move means something different depending on whether you own the thing.

What is deliberately not here

The position’s value. A holding is valued from the statement or the last close on disk, never from the network (see arvo_runtime::portfolio), and putting that figure beside a live price would show two numbers priced two ways as though they agreed. The live price belongs to the watchlist; the valuation belongs to the portfolio, and they stay apart.

Fields

instrument: String

symbol: String

price: Option<f64>

None when the row exists but nothing has priced it yet — no broker session for the snapshot, and no tick arrived for it yet. Optional rather than zero because $0.00 is a price, and a wrong one.

change: Option<f64>

Move since the previous close, as a fraction. None when there is a price but no previous close to measure it against.

held: bool
