NFO:NIFTY24MAY22400PE HTTPSConnectionPool(host='api.kite.trade', port=443): Read timed out. (read timeout=40)
I am using the : 'kite.ltp' to get price for a symbol

I am getting this error so frequently that it prevents any processing.

I tried ping to the 'api.kite.trade' server and i got:
ping api.kite.trade

How often do you call this endpoint?

shrixyz

10 calls after every 6 seconds. It has always been fine and this has started very recently. I think the ping statistics is relevant, packets are lost and time taken is 59ms which is quite high. Ping to google.com resulted in no packets lost and 6ms time.

I tried tracert to api;kite.trade and to google.com:

Maybe you are getting blocked by cloudflare, if that is your frequency then better to use Websocket API.

I also noticed, when these errors occur, Kite web too fails to update chart. Example : if i want to change from Nifty to Banknifty chart, then Kite web takes a long time to bring up the chart.
I have the code running for many years now. I cant modify it to websocket api.

shrixyz

I tried Websockets, the ltp call returned:
b'\x00\x01\x00\x08\x00\r\x80\x01\x00\x01h\x8c'
I referred to Kite Websocket documentation, it says: LTP. Packet contains only the last traded price (8 bytes).
But, i am unable to extract ltp from the bytearray.

Could you please advise how i can get ltp from it. Any code/documentation will be helpful.

b'\x00\x01\x00\x08\x00\r\x80\x01\x00\x01h\x8c'

These are binary data. You can use any of our official client's websocket streams.

shrixyz

I had been using kite to get ltp. But it keeps timing out, hence i was advised to use sockets. If you could just guide me about the bytestream structure for 'ltp' that would be great. Example bytestream: :b'\x00\x01\x00\x08\x00\r\x80\x01\x00\x01h\x8c'

sujith

You can know more about packet structure here.

If you want to reinvent the parsing bit that is already there then you can view ticker code of pykiteconnect.

Thanks, got it. Below is my code snippet in case some user needs it.

rmessage = b'\x00\x01\x00\x08\x00\x03\xe9\t\x00#`r'
b_id = rmessage[-7:-4]
b_ltp = rmessage[-3:]
id = (int.from_bytes(b_id, byteorder='big'))
ltp = (int.from_bytes(b_ltp, byteorder='big') / 100)
print(id, ltp)

Output: 256265 23184.5
