Tick values are refreshing very slowly in websocket streaming.

[leena.1234]

Hello,
I am using SmartWebSocket() for Websocket streaming to fetch script feeds for both Indices ad Equities.

It is observed that, there is a delay in tick values update and LTP is not getting reflected fastly so it's value is differing from the actual price on Angel Broking web console.

So there are 2 major questions-

1. How can we sync with the current prices?
2. Also what is the ideal delay time in tick values update as comparing to Angel Broking web console?

@admin What is SFI ? What is websocket's specialty over LTP or Historical API (Daily to 1 min)
Can we get many stock's data at once by multithreading?

1. You need to go through below documentation to understand all terms related to web socket.
   2)We only provide data for the symbol whose token are available in instrument dump file.

[webseos]

@admin I saw this , filtered out stock equity info of 1522 stocks symbol and token to a JSON file, but didnot parsed FNO data yet because of too much strike prices , expiry data,

Saw different bank nifty , nifty strike, but could not find spot
Can you tell the symbol to FIND exact JSON record for NIFTY Bank NIFTY Spot

[webseos]

@admin Can you show a sample code to get NIFTY/ BankNifty SPOT LTP Data. I think it always same, because NIFTY spot has no expiry

Query : Also can we get LTP of a premium related to a strike / expiry , e,g NIFTY 16000 CE 26 August 2021

Can we get LIVE premium ?

HI @princetech1 our team is working on websocket code we will update you once it is fixed.

@J88913 that link is not useful=> Nothing special to get Hinted.

@admin I want to get spot Nifty and Not Futures.

[princetech1]

@admin token = 'nifty'
task='sfi'
WS = SmartWebSocket(feedToken, CLIENT_ID)

def on_tick(ws, tick):
print("Ticks: {}".format(tick))

def on_open(ws):
#print("on Open")
ws.subscribe(task,token)

def on_connect(ws, response):
ws.send_request(token)

def on_close(ws, code, reason):
ws.stop()

Assign the callbacks.

WS.on_ticks = on_tick
WS.on_connect = on_connect
WS.on_open = on_open
WS.on_close = on_close

WS.connect( )
print(WS)

please check and make the neccesary update in above Code=>

HI @webseos To Get live feed from websocket you need to pass task as "sfi" and pass nifty as token

[J88913]

@princetech1 for the live feed python code watch link text

[admin]

HI @webseos Please go through the instrument dump file.

[webseos]

@admin What will be the code or JSON request format to get BankNifty Spot/ Nifty Spot/ Finnifty Spot

[admin]

HI @princetech1 you can get it though websocket or ltp API.
