Информация о символе.

RAW contract: connectors fill the typed fields as a convenience subset and MUST NOT drop, filter, or canonicalize anything the exchange returned — status carries the venue-native value verbatim, and extra is a raw passthrough of the full native symbol record so nothing is lost. Any normalization / active-only filtering / asset clustering is a STATION concern, never core.

Fields

symbol: String

Символ (как на бирже)

base_asset: String

Базовый актив

quote_asset: String

Котируемый актив

status: String

Статус (TRADING, BREAK, etc.)

price_precision: u8

Точность цены

quantity_precision: u8

Точность количества

min_quantity: Option<f64>

Минимальное количество

max_quantity: Option<f64>

Максимальное количество

tick_size: Option<f64>

Шаг цены (например, 0.01 для 2 знаков после запятой)

step_size: Option<f64>

Шаг количества

min_notional: Option<f64>

Минимальный notional (price * qty)

account_type: AccountType

Account / market type this symbol belongs to (Spot, FuturesCross, etc.)

instrument_type: Option<String>

Native instrument/contract-type token exactly as the exchange reports it, RAW (e.g. "PERPETUAL", "SWAP", "linear", "FUTURE", "OPTION", "spot"). None when the venue does not distinguish. NOT normalized — station maps it if a consumer wants a canonical enum.

extra: Value

RAW passthrough of the exchange’s native symbol record — every field the venue returned, verbatim. The typed fields above are a convenience subset; extra guarantees nothing the exchange said is lost. Null only if a connector hasn’t been wired for passthrough yet.
