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.

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 off the live price stream.

Typed rather than a View: there are hundreds a minute, and the four fields are the whole of it. Display only — a tick never becomes a bar, because the data library is fetched files with a content hash and that hash is what makes a stored verdict checkable. One price, as it arrived.

Separate from QuoteView and deliberately thinner: a tick carries only what moved. Which rows exist, and which of them you hold, is settled once by the Watchlist call — a stream that also decided the row set would make a socket blip look like a portfolio change.

regular is not decoration. Outside 09:30–16:00 the stream keeps sending, on thin volume and wide spreads, and a pre-market print rendered identically to a regular-session one is a worse answer than no price at all. A front end marks it; it does not hide it.

Fields

symbol: String

The bare ticker, matching QuoteView.symbol.

price: f64

change: Option<f64>

Move since the previous close, as a fraction.

regular: bool

Whether this print happened in the regular session.
