{
// Let us open a web socket
var ws = new WebSocket("wss://websocket.kite.trade/?api_key=&user_id=DV3508&public_token=");
ws.binaryType = "arraybuffer";
ws.onopen = function()
{
// Web Socket is connected, send data using send()
var message = {"a": "subscribe", "v": ["full", [131098372]]};
ws.send(JSON.stringify(message))
};
ws.onmessage = function (t)
{
if(t.data instanceof ArrayBuffer) {
/* if(t.data.byteLength > 2) {} */
console.log(t.data.byteLength);
}
};
ws.onclose = function()
{
// websocket is closed.
console.log("Connection is closed...");
};
}

{
// The browser doesn't support WebSocket
alert("WebSocket NOT supported by your Browser!");
}
}
