// provider: (美股市場: "US", 台股市場: "Taiwan", 加密貨幣: "Binance")
socket.addEventListener('open', function (event) {
//訂閱美股蘋果 symbol: "AAPL"
socket.send(
JSON.stringify({
event: 'subscribe',
data: {symbol: 'AAPL', provider: 'US'},
}),
);
//訂閱台股台積電 symbol: "2330"
socket.send(
JSON.stringify({
event: 'subscribe',
data: {symbol: '2330', provider: 'Taiwan'},
}),
);
//訂閱比特幣 symbol: "BTCUSDT", 須帶上market區分合約/現貨市場，合約為 "FutureMarket"/現貨為"Client"
socket.send(
JSON.stringify({
event: 'subscribe',
data: {symbol: 'BTCUSDT', provider: 'Binance', market: 'Client'},
}),
);
});
3. 訂閱標的後，監聽'message'事件，即可獲得已訂閱商品即時行情
