NetworkException in kite.margins() call

mlearner

I got following exception during market hours when I was trying to fetch margin for my account.

Any idea why this occurred and how can I prevent it? Should I just reattempt kite.margins() call when this kind of exception occurs?

margin = kite.margins()

  File "/home/ubuntu/.local/lib/python3.8/site-packages/kiteconnect/connect.py", line 315, in margins

    return self._get("user.margins")

  File "/home/ubuntu/.local/lib/python3.8/site-packages/kiteconnect/connect.py", line 817, in _get

    return self._request(route, "GET", params)

  File "/home/ubuntu/.local/lib/python3.8/site-packages/kiteconnect/connect.py", line 886, in _request

    raise exp(data["message"], code=r.status_code)

kiteconnect.exceptions.NetworkException: request WC1ZW1wDSlFL4TRDi1GTKbfQ3uRGlzl3 timed out

Are you trying to run this during post-mid-night?
As post-midnight OMS runs the BOD process till around 6:30 AM and during that time it will not accept any requests.

mlearner

No @rakeshr, this exception occurred during market hours on 2 Jun '21.

Is it continuously happening? If not, then you need to handle this network time-out exception at your end and make the same request again with a few ms delay.

No it is not continuously happening. Happened just once. Sure, will handle this exception and will make a request again with some delay. Thanks.

One more doubt, since I can only make a finite recursive calls in Python (999 to be precise), if the network issue between Kite and OMS persists for a longer duration say for 5 min or so(could be realistically even higher), all my retry attempts would be over in this much time.

Can you please suggest a way to handle such unforeseen API downtime in future?

You can retry with exponential backoff method which is like first time it will retry of 5 seconds, 10 seconds, and then 15 seconds and so on.

@sujith - Got it. Thanks.
