Stream Coinbase Advanced Trade market data (ticker, level2, market_trades, candles) and authenticated user channels with HMAC/JWT signing.
Resposta rápida: TsgcWSAPI_Coinbase é o componente do sgcWebSockets que conecta aplicativos Delphi e C++ Builder ao Coinbase Advanced Trade. Ele transmite os canais públicos de mercado (ticker, level2, market_trades, candles) e o canal de usuário assinado usando autenticação HMAC ou JWT.
Coinbase Advanced Trade client — ticker, level2 order book, market_trades, candles, status and the authenticated user channel.

Pair with a TsgcWebSocketClient, supply API key/secret for signed channels, then subscribe to ticker, level2, market_trades or user.
uses
sgcWebSocket, sgcWebSocket_API_Coinbase;
var
WSClient: TsgcWebSocketClient;
Coinbase: TsgcWSAPI_Coinbase;

WSClient := TsgcWebSocketClient.Create(nil);

TsgcWebSocketClient *WSClient = new TsgcWebSocketClient(this);
TsgcWSAPI_Coinbase *Coinbase = new TsgcWSAPI_Coinbase(this);
Coinbase->Client = WSClient;
WSClient->Active = true;
Coinbase->SubscribeTicker(OPENARRAY(UnicodeString, ("BTC-USD")));
Coinbase->SubscribeLevel2(OPENARRAY(UnicodeString, ("BTC-USD")));Advanced Trade streams: ticker, ticker_batch, level2, market_trades, candles, status, plus the authenticated user channel.
SubscribeTicker, SubscribeTickerBatch, SubscribeLevel2, SubscribeMarketTrades, SubscribeCandles and SubscribeStatus handle every Advanced Trade public stream.
SubscribeUser opens the authenticated user channel and delivers order, fill and account-level events for the signed-in identity.
Coinbase Advanced Trade supports both legacy HMAC signing and newer JWT auth — the component picks the right scheme based on the credentials supplied.
level2 and market_trades deliver a sequence_num per envelope; the component watches for gaps and raises OnException if a re-subscribe is required.
Every subscribe call accepts an array of product IDs (BTC-USD, ETH-USD, ...) so a single connection can multiplex hundreds of instruments.
For snapshot data and order placement use the REST counterpart — the WebSocket component focuses on real-time streams.

Dúvidas comuns sobre o componente da API Coinbase para Delphi e C++ Builder.
TsgcWebSocketClient e um TsgcWSAPI_Coinbase no seu formulário, atribua o client à propriedade Client do componente da API, defina Coinbase.ApiKey e Coinbase.ApiSecret se você precisar do canal de usuário e, em seguida, defina WSClient.Active := True e chame métodos de subscrição como SubscribeTicker ou SubscribeLevel2.TsgcWSAPI_Coinbase foca na API WebSocket do Coinbase Advanced Trade: os canais públicos (ticker, ticker_batch, level2, market_trades, candles, status) e o canal de usuário autenticado. Para dados de snapshot e envio de ordens, use a contraparte REST; o componente WebSocket cuida dos streams em tempo real.
