衍生一檔與試撮欄位

• derivedBid／derivedAsk（延伸一檔）主要出現於價差合約之衍生報價，一般期貨通常為 price=0／size=0。
• isTrial 於商品處於試撮階段時可能為 true，包含開盤前試撮與盤中緩搓／試撮；正常連續撮合時，欄位可能為 false 或不出現。
• 上述期權進階行情欄位隨功能分階段啟用，未啟用前不會出現於回應中。

Example

Subscribe channel

Python

from fubon_neo.sdk import FubonSDK, Order

def handle_message(message):
    print(f'market data message: {message}')

sdk = FubonSDK()
accounts = sdk.login("Your ID", "Your password", "Your cert path", "Your cert password")  # 需登入後，才能取得行情權限

sdk.init_realtime() # 建立行情連線

futopt = sdk.marketdata.websocket_client.futopt
futopt.on('message', handle_message)
futopt.connect()
futopt.subscribe({ 
    'channel': 'books', 
    'symbol': 'TXFA4'
    #'afterHours' : True   # 夜盤行情
})

Node.js

const { FubonSDK } = require('fubon-neo');

const sdk = new FubonSDK();

const accounts = sdk.login("Your ID", "Your password", "Your cert path", "Your cert password");

sdk.initRealtime(); // 建立行情連線

const futopt = sdk.marketdata.webSocketClient.futopt;

futopt.connect().then(() => {
  futopt.subscribe({ 
                     channel: "books", 
                     symbol: "TXFA4" 
                     // afterHours: true    //夜盤行情 
                   });
});

futopt.on("message", (message) => {
  const data = JSON.parse(message);
  console.log(data);
});

C#

using FubonNeo.Sdk;

var sdk = new FubonSDK();

var result = sdk.Login("Your ID", "Your password", "Your cert path", "Your cert password");

sdk.InitRealtime();  // 建立行情連線

var futopt = sdk.MarketData.WebSocketClient.FutureOption;

futopt.OnMessage += (msg) => Console.WriteLine($"receive: { msg }");

await futopt.Connect();

await futopt.Subscribe(FugleMarketData.WebsocketModels.FutureOptionChannel.Books, "TXFA4");

// await futopt.Subscribe(FugleMarketData.WebsocketModels.FutureOptionChannel.Books,  new FutureOptionParams { Symbol = "TXFC4", AfterHours = true });  // 夜盤行情
