Delphi Kucoin Futures API Client

How Use the WebSocket Feed API 

In order to connect to Kucoin WebSocket API, just create a new Kucoin API client and attach to TsgcWebSocketClient.

See below an example:

oClient := TsgcWebSocketClient.Create(nil);
oKucoin := TsgcWSAPI_Kucoin_Futures.Create(nil);
oKucoin.Client := oClient;
oClient.Active := True; 

Kucoin offers a variety of channels where you can subscribe to get real-time updates of market data, orders... Find below a sample of how subscribe to a Ticker:

oClient := TsgcWebSocketClient.Create(nil);
oKucoin := TsgcWSAPI_Kucoin_Futures.Create(nil);
oKucoin.Client := oClient;
oKucoin.SubscribeSymbolTickerV2('XBTUSDM');

procedure OnMessage(Connection: TsgcWSConnection; const aText: string);
begin
// here you will receive the ticker updates
end; 

How Place Orders 

First you must create an API Key in your Kucoin account and add privileges to trading with Futures.

Once this is done, you can start futures trading.

First, set your ApiKey, ApiSecret and Passphrase in the Kucoin Client Component, this will be used to sign the requests sent to Kucoin server.

// Place Market Order 1 XBTUSDM
oKucoin := TsgcWSAPI_Kucoin_Futures.Create(nil);
oKucoin.Kucoin.ApiKey := '<api key>';
oKucoin.Kucoin.ApiSecret := '<api secret>';
oKucoin.Kucoin.Passphrase := '<passphrase>';
ShowMessage(oKucoin.REST_API.PlaceMarketOrder(kosBuy, 'XBTUSDM', 1));

// Place Limit Order 1 XBTUSDM at 40000
oKucoin := TsgcWSAPI_Kucoin_Futures.Create(nil);
oKucoin.Kucoin.ApiKey := '<api key>';
oKucoin.Kucoin.ApiSecret := '<api secret>';
oKucoin.Kucoin.Passphrase := '<passphrase>';
ShowMessage(oKucoin.REST_API.PlaceLimitOrder(kosBuy, 'XBTUSDM', 1, 40000));
