@nirav

can you please share the code and your sdk version ( if you are using python )

admin

@rajanprabu @ nirav
kindly generate feed token and use below code.

ss = WebSocket(FEED_TOKEN, CLIENT_CODE)

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

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

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

Assign the callbacks.

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

ss.connect( )`

@admin said in not receiving proper WebSocket data:

ws.send_request(token)

for SDK version 1.2.2 onwards this needs to be

ws.send_request(token,task)

where task is task="mw", #'mw'|'sfi'|'dp'

@nirav

No, OI is not streamed via WebSocket. It's yet to be added in WebSocket response.

@admin
Can you give any rough estimate when will you start streaming OI ?

@nirav

This normally happens with network drop. If you are using new python SDK, you may potentially overcome this.

@rajanprabu

@nirav

Its hard to suggest with fewer details available. Are you running it on the cloud or at home with Wifi ? WiFi drop can also cause this.

@admin facing same issue, only receving tm data

[{"tvalue":"16/02/2023 11:35:12","name":"tm"}]
[{"tvalue":"16/02/2023 11:35:13","name":"tm"}]
[{"tvalue":"16/02/2023 11:35:14","name":"tm"}]
[{"tvalue":"16/02/2023 11:35:15","name":"tm"}]

Here is code :

var ws =new websocket('', '',"nse_cm|2885", "mw");
ws.connection().then(() => {
ws.runScript("nse_cm|2885&nse_cm|1594&nse_cm|11536", "mw|sf|dp");
setTimeout(function () {
ws.close()
}, 30000)
});
ws.on('tick', receiveTick);

function receiveTick(data) {
	console.log(data);			  
}
