Web socket scripts stop at random times

[jiwan1986]

@Ashok No need to create object for logger. You can use my code. I'm using that code and I'm able to see all the exceptions including heartbeat failed.

[jiwan1986]

@Ashok I haven't encountered this issue yesterday, though sometimes heartbeat failed. I was receiving the ticks even though the heartbeats failed message kept coming. Socket was reconnected but heartbeat function was not aware about it. There is issue with heartbeat function which should be resolved as soon as possible. This is why it is important to place SL order right after the first order is placed. Because you don't know when something gets broken in future. @admin please look into this.

Hi @rjbanna We have already reported the issue to the team we are trying to solve it asap.

@rjbanna @Ashok

Yes I faced it twice yesterday.. But whoever this happened I normally stopped the script and restarted it. I think angel team is working on it.

[jiwan1986]

@rajanprabu Yes, I do the same but my algo make use of some past calculations and live candles. So if I start it again, I would need to calculate all the values manually which is cumbersome process. Angel team is working on it.

@rjbanna

Agreed.. its pretty hard. Hope this gets resolved soon.

[admin]

@rajanprabu @rjbanna @Ashok we have tried to handle all this issues in the new version of python sdk.We will be testing it and reverting you back soon.

[Ashok]

@rjbanna, Still am not very sure on it... If its not too much trouble, shall we connect privately ?

@admin

I have tested the new SDK.. so far it passed all my stress tests.. I will continue my testing and I will keep it posted. Thanks to the team. Very good job.

[jiwan1986]

@admin I'm also testing the new SDK, no issues till now. Thanks for quick issue resolution.

[Ashok]

@admin @rjbanna Thanks. Moved to new SDK 1.2.3 now... Thanks for support

@Ashok

Pease note new SDK needs changes to the script. You need to add ws.websocket_connection() to on_connect

from smartapi import WebSocket 
FEED_TOKEN= "your feed token"
CLIENT_CODE="your client Id"
token="channel you want the information of" #"nse_cm|2885&nse_cm|1594&nse_cm|11536"
task="task" #"mw"|"sfi"|"dp"
ss = WebSocket(FEED_TOKEN, CLIENT_CODE)

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

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