Livefeed using sockets

rjbanna

I'm having issue fetching the live feed using the API. I tried the sample code given on the Github but somehow I'm not able to get the live feed. Below is the code I used. If anybody knows how to resolve this, please let me know.

CODE

import logging
from smartapi import SmartConnect, SmartSocket

obj = SmartConnect(api_key="API_KEY")
data = obj.generateSession("CLIENT_ID","PWD")
tokens = obj.generateToken(data['data']['refreshToken'])

feedToken = tokens['data']['feedToken']
token = 'nse_cm|2885'

logging.debug(feedToken)

ss = SmartSocket(feedToken, 'CLIENT_ID')

def on_tick(ws, tick):
	logging.debug("Ticks: {}".format(ticks))

def on_connect(ws, response):
	logging.debug("on connect")
	ws.send_request(token)

def on_error(ws, code, reason):
	logging.debug("Connection error: {code} - {reason}".format(code=code, reason=reason))

def on_close(ws, code, reason):
	logging.debug("on close")
	ws.stop()


ss.on_ticks = on_tick
ss.on_connect = on_connect
ss.on_error = on_error
ss.on_close = on_close

ss.connect(threaded = True)

while True:
	def on_ticks(ws, ticks):
		helper_method(ticks)

	def helper_method(ticks):
		print("Ticks received from while loop: {}".format(tick))

	ss.on_ticks = on_ticks

What does the response key:values mean?
Would be helpful if someone can explain what does the below values like tm,tvalue,ak,msg,etc mean, where can i find the documentation for these?

Ticks: [{'name': 'tm', 'tvalue': '25/02/2021 23:31:21'}
Ticks: [{'ak': 'ok', 'msg': 'connected', 'task': 'cn'}]

@rajanprabu are you asking about the error faced in Dec ? That is due to wrong formatting of the input text to the WS Script

rajanprabu

@Ashok what was wrong ??

@admin Thanks for your help. The issue is solved.

Hi @dheepi , please share your contact details on api@angelbroking.com

@admin @vishant .

I am facing the exact issue faced by @dushyant . Even I used the same token: 3045 which is the token for SBIN-EQ.

{"token":"3045","symbol":"SBIN-EQ","name":"SBIN","expiry":"","strike":"-1.000000","lotsize":"1","instrumenttype":"","exch_seg":"NSE","tick_size":"5.000000"}

The data is from the instruments API. which means the instrument data is wrong?

Hi @dushyant , I suppose you're passing wrong feedToken. Please review.

dushyant

Hi @admin @bhaveshjain I am using latest SMARTAPI-PYTHON and getting the below output only for token="nse_cm|3045". I have tried few more ticks as well but still getting the same output.

Ticks: [{'ak': 'nk', 'msg': 'hb', 'task': 'hb'}]
Ticks: [{'ak': 'nk', 'msg': 'hb', 'task': 'hb'}]
Ticks: [{'ak': 'nk', 'msg': 'hb', 'task': 'hb'}]
Ticks: [{'ak': 'nk', 'msg': 'hb', 'task': 'hb'}]
Ticks: [{'ak': 'nk', 'msg': 'hb', 'task': 'hb'}]
Ticks: [{'ak': 'nk', 'msg': 'hb', 'task': 'hb'}]

Please let me know how can I get data.

@vishant I have created the new thread for the same.

vishant

Hi @rjbanna,

Request you to raise this same query as a general discussion. So that other people will also be informed about this.

rjbanna

@bhaveshjain Can you please elaborate following terms that I receive as a response from socket? They are to, lo, sp, c(if this is close, then which close is it referring to?), tk, bs, bp, cng, bq, ap, nc, name, tbq.

rjbanna

@bhaveshjain I checked the websocket API and it is working as expected. There is one typo in the README.md file on Github. In the code feedToken=obj.getFeedToken(), the function name is misspelt. In the smartConnect.py file, the function name is getfeedToken(). with the "feed" in lowercase where as in the example it is "Feed" with first letter capital. So kindly resolve that issue or else people will receive the following error "'SmartConnect object has no attribute 'getFeedToken'". Thanks

rjbanna

@bhaveshjain Sure, I'll check it and let you know soon.
