limit on the number of NFO tickers I can subscribe to ?

@rakeshr ,
Hi,
Could you please let me know how to put socket data for multiple stocks in particular manner so that same can be used for generating candle sticks?

Below code is for one stock and generating tick data in 10.txt file. Now I want multiple stock tick in particular manner for every 5 seconds.
Example:
@ zero second
Reliance - 970
Yesbank - 350
Biocon - 400
after 5 seconds
Reliance - 972
Yesbank - 352
Biocon - 403 Something like this. They should not be shuffle

Python Code:
{
from kiteconnect import KiteConnect
api_key=open('api_key.txt','r').read()
api_secret=open('api_secret.txt','r').read()
kite=KiteConnect(api_key=api_key)
kite.set_access_token(open('access_token.txt','r').read())
import datetime
import os
import time
os.environ["TZ"] = "Asia/Kolkata"
time.tzset()
import logging
from kiteconnect import KiteTicker
access_token=(open('access_token.txt','r').read())
logging.basicConfig(level=logging.DEBUG)
kws = KiteTicker("my api key",access_token)
from time import sleep
import time
import xlrd
workbook = xlrd.open_workbook('LP.xls')
worksheet = workbook.sheet_by_index(1)
H2=round(worksheet.cell(10, 14).value)
M2=round(worksheet.cell(10, 15).value)
INTER=round(worksheet.cell(10, 16).value)
INSTR=round(worksheet.cell(10, 9).value)
start_time = datetime.time(H2,M2,0,0)
first_tick_flag = True
def on_ticks(ws, ticks):
global first_tick_flag,start_time
if first_tick_flag:
first_tick_flag = False
start_time = time.time()
end_time = time.time()
if int(end_time - start_time) >=INTER:
start_time = end_time
for tick in ticks:
YB=tick['last_price']
rt1=datetime.datetime.now()
with open('10.txt', 'a') as file:
file.write(str(YB)+"\n")
file.write(str(rt1)+"\n")
def on_connect(ws,response):
ws.subscribe([INSTR])
ws.set_mode(ws.MODE_LTP, [INSTR])
def on_close(ws,code,reason):
ws.stop()
kws.on_ticks=on_ticks
kws.on_connect=on_connect
kws.on_close=on_close
kws.connect()
}

Thank you in advance.
