 When implementing an exchange library, use `LibraryHelpers.IsStableCoin`, `IsCommodity`, and `IsEquity` only as best-effort classifiers and supply exchange-specific additions where needed.
 
+## Shared market-data quantities

+In 12.4.0, use `SharedOrderQuantity`-valued `Volumes` on shared spot/futures tickers and klines, and `Quantities` on shared trades. The scalar `Volume`, `QuoteVolume`, and `Quantity` members are obsolete.
+
 ## Result pattern
 
 REST methods return `HttpResult<T>` and websocket subscription methods return `WebSocketResult<UpdateSubscription>`. Always check `.Success`. `.Exchange` property identifies which exchange responded — useful for logging.

+CryptoExchange.Net 12.4.0 uses `SharedOrderQuantity` for market-data quantities. Prefer `Volumes` on `SharedSpotTicker`, `SharedFuturesTicker`, and `SharedKline`, and `Quantities` on `SharedTrade`; the scalar `Volume`, `QuoteVolume`, and `Quantity` members are obsolete.

 ## Single-exchange code uses the exchange's own client
 
 For Binance-only code, use `BinanceRestClient` directly (see Binance.Net repo `AGENTS.md`). SharedApis is for portability — use it when you need that.

 For exchange-library implementations, `LibraryHelpers.IsStableCoin`, `IsCommodity`, and `IsEquity` provide best-effort classification of known assets and accept exchange-specific additions. These helpers are heuristics, not an exhaustive source of truth.
 
+## Shared Market-Data Quantities
+
+Since CryptoExchange.Net 12.4.0, shared market-data models use `SharedOrderQuantity` so base-asset, quote-asset, and contract quantities remain explicit.

The former scalar `Volume`, `QuoteVolume`, and `Quantity` members are obsolete.

 > Base C#/.NET library for cryptocurrency exchange API client implementations. Provides a standardized abstraction (REST, WebSocket, authentication, rate limiting, error handling, order book management, shared cross-exchange interfaces) that 28+ exchange-specific libraries are built on top of.
 
-CryptoExchange.Net itself is not used directly — install one of the exchange-specific libraries (Binance.Net, Bybit.Net, OKX.Net, Kraken.Net, Coinbase.Net, etc.) or `CryptoClients.Net` to access all exchanges via a single bundle. The base library is what makes the entire ecosystem feel consistent: same `HttpResult<T>` REST result pattern, same `WebSocketResult<UpdateSubscription>` websocket subscription pattern, same DI registration, same shared interfaces across all exchanges. Current version: 12.3.0. Targets netstandard2.0, netstandard2.1, net8.0, net9.0, net10.0. Native AOT supported.

 The standout feature for cross-exchange code is `CryptoExchange.Net.SharedApis` — a set of interfaces (`ISpotTickerRestClient`, `ISpotOrderRestClient`, `IBalanceRestClient`, etc.) implemented by every exchange library. Same call signature works against any exchange.
 
 Version 12.2.0 adds typed asset metadata to shared symbol discovery. `SharedSpotSymbol` and `SharedFuturesSymbol` expose `DisplayName` plus base/quote `SharedAssetType` and `SharedAssetSubType` values. `GetSymbolsRequest` can filter on those four type fields. After symbol discovery, `ISpotSymbolRestClient.SpotSymbolCatalog` and `IFuturesSymbolRestClient.FuturesSymbolCatalog` provide asset and symbol dictionaries; each catalog is available only after the corresponding `Get*SymbolsAsync` call. `LibraryHelpers.IsStableCoin`, `IsCommodity`, and `IsEquity` are best-effort helpers for exchange-library implementations.
 
+Version 12.4.0 represents market-data quantities with `SharedOrderQuantity`: use `Volumes` on `SharedSpotTicker`, `SharedFuturesTicker`, and `SharedKline`, and `Quantities` on `SharedTrade`. The old scalar `Volume`, `QuoteVolume`, and `Quantity` members are obsolete. Exchange-library implementations must pass `SharedOrderQuantity` to these model constructors.
