Remarks

The exchange.GetMarkets() function returns a dictionary containing this Market structure.

Exchanges differ in how much market information they provide, so note the following: MaxQty and MaxNotional are 9007199254740991 (meaning no limit) when the exchange does not provide them; MaxNotional, CtVal and CtValCcy are omitted when there is no data (spot symbols usually have no CtVal/CtValCcy; the Rust Market structure always has these fields, which are then 0 or an empty string); PricePrecision and AmountPrecision can be negative; exchanges without a market list endpoint cannot provide the native name, in which case Symbol is the FMZ trading symbol code (such as BTC_USDT). All field values above are derived from the exchange interface's raw data, and specific details can also be found in the Info field content.
