Kraken WebSocket API
Subscribe to Kraken v2 public channels (ticker, book, trade, ohlc, spread) and authenticated private channels (openOrders, ownTrades) from a typed Delphi component.
Subscribe to Kraken v2 public channels (ticker, book, trade, ohlc, spread) and authenticated private channels (openOrders, ownTrades) from a typed Delphi component.
Kraken WebSocket v2 client — ticker, book, trade, ohlc and spread channels plus signed openOrders / ownTrades private streams.
TsgcWSAPI_Kraken
Windows, macOS, Linux, iOS, Android
Standard / Professional / Enterprise
Pair with a TsgcWebSocketClient, fetch a WebSocket token if you need private channels, then subscribe to public or authenticated streams.

SubscribeTicker, SubscribeBook, SubscribeTrade, SubscribeOHLC, SubscribeSpread and SubscribeInstrument cover every Kraken WebSocket v2 public channel.
SubscribeOpenOrders, SubscribeOwnTrades, SubscribeBalances open authenticated streams — the component obtains the WebSocket token via the signed REST call automatically.
Every subscribe call accepts an array of symbols so one connection multiplexes any number of pairs.
The v2 RPC verbs (add_order, cancel_order, cancel_all, edit_order, batch_add, batch_cancel) are exposed as typed methods.
Book subscriptions deliver an initial snapshot followed by incremental updates — ideal for maintaining a synchronised local order book.
Kraken v2 messages carry a sequence_num inside the relevant channels — the component watches for gaps and signals via OnException if resubscription is needed.
