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.
