i am trying to get ltp data for instruments inserted in database but it returns less data then given instruments if i give 11 instruments it returns me only 7 instruments data how it is possible I am posting my code here

function calll(val)
{
	//alert(val);
	ws= new WebSocket("wss://websocket.kite.trade/?api_key=xxxx&user_id=yyyy&public_token=xyzw");
	message = "{\"a\": \"mode\", \"v\": [\"ltp\", ["+val+"]]}";
       // alert(message);
	ws.binaryType = 'arraybuffer'
	ws.send(message)
	ws.onmessage = function (event) {
        var dat=convert(event.data);
        //alert(event.data);
 //   alert(dat);
    if(dat.length>1)
    {
    var curr=0;
    var count=(dat[1]) | 
              (dat[0] << 8);
         //     alert(count);
    curr=curr+2;              
    for(i=0;i<count;i++)
    {
        var l=(dat[curr+1]) | 
              (dat[curr] << 8); 
        curr=curr+2;
        var result = ((dat[curr+3]) | 
              (dat[curr+2] << 8) | 
              (dat[curr+1] << 16) | 
              (dat[curr] << 24));
       // alert(result);
        curr=curr+4;
        var price = ((dat[curr+3]) | 
              (dat[curr+2] << 8) | 
              (dat[curr+1] << 16) | 
              (dat[curr] << 24));
        curr=curr+4;
        price=price/100;
        //alert(result+","+price);
    }       
    //alert(count+","+ByCount);
    
             // alert(result);
    }     
    //alert(makeInt(dat[11],dat[10],dat[9],dat[8]);
}
function convert(data) {
     return new Uint8Array(data);
}	

Here when i send 10 instruments token in val variable it shows alert of message properly
in onmessage() it shows 7 count only

You can check out example for Websockets.

Once you subscribe you will get first tick post that you will only get ticks if the value changes.

I am new to Kite Connect. Can someone please tell if there are any charges for using ticker data through API?
