Mismatch in day_high from Dhan WebSocket vs chart data

APIs, Automation, Algos & Code
1

Hi everyone,

I’m using the DhanHQ WebSocket API for live market data and noticed a discrepancy.

Instrument: NIFTY 13 APR 23850 CE
SID: 54806
Time: Around 09:15 AM

From WebSocket:

  • day_high = 291

But on the chart (5-second timeframe):

  • The high of the 09:15 candle is around 262

  • I don’t see any price reaching 291

I have attached:

  1. WebSocket log screenshot

  2. Chart screenshot

Is this expected behavior?

  • Does day_high include very brief tick spikes not visible on candles?

  • Or could this be a data inconsistency?

Would appreciate any clarification.

Thanks!
