How to map the token number with their symbol name?
I have subscribe RELIANCE_EQ's token number.token = "nse_cm|2885" # Token number of RELIANCE_EQ task = "mw" # "mw"|"sfi"|"dp"And stream the WebSocket. It's perfectly works.
[{'ak': 'ok', 'msg': 'heartbeat', 'task': 'hb'}] [] [{'e': 'nse_cm', 'ltp': '2038.50', 'ltq': '20', 'ltt': 'NA', 'name': 'sf', 'tk': '2885'}] [{'name': 'tm', 'tvalue': '31/03/2021 09:52:10'}] [{'ap': '2031.81', 'bp': '2038.05', 'bq': '44', 'bs': '121', 'c': '2029.30', 'cng': '09.20', 'e': 'nse_cm', 'lo': '2011.60', 'ltp': '2038.50', 'ltq': '10', 'ltt': '31/03/2021 09:52:10', 'name': 'sf', 'nc': '00.45', 'sp': '2038.50', 'tbq': '319613', 'tk': '2885', 'to': '2680052885.07', 'tsq': '321701', 'v': '1319047'}] [{'e': 'nse_cm', 'ltp': '2038.50', 'ltq': '25', 'ltt': 'NA', 'name': 'sf', 'tk': '2885'}] [{'name': 'tm', 'tvalue': '31/03/2021 09:52:11'}] [{'ap': '2031.81', 'bp': '2038.00', 'bq': '291', 'bs': '23', 'c': '2029.30', 'cng': '09.20', 'e': 'nse_cm', 'lo': '2011.60', 'ltp': '2038.50', 'ltq': '2', 'ltt': '31/03/2021 09:52:11', 'name': 'sf', 'nc': '00.45', 'sp': '2038.50', 'tbq': '320028', 'tk': '2885', 'to': '2680540519.47', 'tsq': '321777', 'v': '1319287'}] [{'e': 'nse_cm', 'ltp': '2038.50', 'ltq': '2', 'ltt': 'NA', 'name': 'sf', 'tk': '2885'}] [{'name': 'tm', 'tvalue': '31/03/2021 09:52:12'}] [{'ap': '2031.81', 'bp': '2038.05', 'bq': '161', 'bs': '12', 'c': '2029.30', 'cng': '09.20', 'e': 'nse_cm', 'lo': '2011.60', 'ltp': '2038.50', 'ltq': '6', 'ltt': '31/03/2021 09:52:12', 'name': 'sf', 'nc': '00.45', 'sp': '2038.50', 'tbq': '320288', 'tk': '2885', 'to': '2680570996.62', 'tsq': '321742', 'v': '1319302'}]But the problem is it's showing messy especially when we subscribe multiple tokens. So how can we map the token number with their symbol name and display that like this__
RELIANCE_EQ:- tk: 2885, ltp:2038.50, to: 2680570996.62Can anyone please give any idea to do that.......

@nayan_nandi You get 'tk' in tick response. Here you have subscribed to reliance and token for that is 2885. Now if you take a look at response, you would find key named 'tk' which is token for that scrip. You can compare the 'tk' to determine the corresponding scrip.
-
@rjbanna Yes Sir, but here has two type of response.
[{'ap': '2031.81', 'bp': '2038.05', 'bq': '44', 'bs': '121', 'c': '2029.30', 'cng': '09.20', 'e': 'nse_cm', 'lo': '2011.60', 'ltp': '2038.50', 'ltq': '10', 'ltt': '31/03/2021 09:52:10', 'name': 'sf', 'nc': '00.45', 'sp': '2038.50', 'tbq': '319613', 'tk': '2885', 'to': '2680052885.07', 'tsq': '321701', 'v': '1319047'}] [{'e': 'nse_cm', 'ltp': '2038.50', 'ltq': '25', 'ltt': 'NA', 'name': 'sf', 'tk': '2885'}]So how can I select first one programmatically, not second one?
-
@nayan_nandi I see some patterns in both the responses. For the first response, you can see 'ltt' has the time value but in the second response, 'ltt' is NA. So I believe you can use that key to differentiate between the two. You have to check if this is true for all the responses.
-
You have to search for keys in the dictionary.. next tick comes with ltt NA because it was only volume/quote change and not transaction. Thats my understanding.

@rajanprabu Can anyone please tell me what is wrong with this code__
token = "nse_cm|2885&nse_cm|3465&nse_cm|1660" task = "mw" # "mw"|"sfi"|"dp" ss = WebSocket(FEED_TOKEN, CLIENT_CODE) trading_portfolio = {"nse_cm|2885": "RELIANCE", "nse_cm|3465": "TATAMOTORS", "nse_cm|1660": "ITC"} def on_tick(ws, tick): for single_company in tick: inst_of_single_company = single_company['tk'] name = trading_portfolio[inst_of_single_company] print(single_company, name)I'm getting error like this____

@nayan_nandi You need to handle exceptions. Key 'tk' won't be in every ticks. You have to add additional if condition after for loop.
if single_company.get('tk'): #do something
