Delay in Nifty Index Ticks, but Options Data is Fine - Data Provider Issue?

jaimin_blackqr · July 11

I'm encountering a strange issue where I'm seeing a significant delay (30+ seconds) specifically in the Nifty index tick data from WebSocket feed. During these periods, the tick data for all my other subscribed option symbols continues to arrive perfectly in real-time without any delay.

My monitoring system caught the issue and generated the following alert, which shows that no new Nifty tick had been received for over 30 seconds, while everything else was working.

2025-07-11 12:47:01.201 (#Log Time): 
ALERT - NO TICK DATA RECEIVED ORDER MANAGEMENT {'tradable': False, 'mode': 'full', 'instrument_token': 256265, 'last_price': 25182.45, 'ohlc': {'high': 25322.45, 'low': 25136.75, 'open': 25255.5, 'close': 25355.25}, 
'exchange_timestamp': datetime.datetime(2025, 7, 11, 12, 46, 31),  # time from provider
'received_timestamp': datetime.datetime(2025, 7, 11, 12, 46, 32, 230084)} # time when code received data

Since the delay is isolated only to the Nifty index instrument and not affecting my other option symbol subscriptions, I suspect the issue might be originating from the data provider's end.

Has anyone else experienced similar selective delays specifically for an index while other instruments are fine?

Thanks for any insights!

@salim_chisty Thanks for response

Today, this issue occurred again; it happens daily at a random time, and the Option data is getting properly. Please see the logs below.

We're checking this and will provide an update shortly.

jaimin_blackqr · July 17

Today, no alerts are generated for index tick data. Seems everything is working fine now.

Is anything updated on your side for the same? just want to confirm @salim_chisty

jaimin_blackqr · July 21

Hello @Nivas @salim_chisty

No alert has been generated from the past few days, and working well. Is this issue on your end?
Waiting for your reply

Nivas · July 21

@jaimin_blackqr We haven't made any changes on our end. It's possible that some ticks were missed due to latency or connectivity issues.

Additionally, we use the same tick data to form OHLCV candles as displayed on the Kite charts, so unless you are inadvertently blocking the ticker (which can cause missed ticks) or not storing/dumping the tick data correctly in a file or database, I don't see any other reason. You might want to try out this example for further verification.

Thanks for your response. I found the cause — it turned out to be an issue related to Redis.

Howdy, Stranger!
