      Hello Team,

      Until Friday, 5 June 2026, the market data received from Angel’s live WebSocket matched our exchange data vendor across all instruments after ignoring ticks that have 0 Angel Calculated LTQ.

      Since Monday, 8 June 2026, we have observed discrepancies in LTP and traded quantity data. This appears to indicate a possible issue with Angel’s market data feed.

      For example, for NIFTY16JUN2623300CE:

      Datetime Vendor LTP Angel LTP Vendor LTQ Angel Calculated LTQ
      10062026 11:20:03 221.15 221.15 27,885 27,885
      10062026 11:20:05 221.60 220.85 8,190 10,270
      10062026 11:20:06 221.90 221.90 17,290 15,210
      10062026 11:20:08 221.70 221.70 5,200 5,200

      The calculated LTQ is derived as:

      Current volume_traded_for_the_day − Previous volume_traded_for_the_day

      Could you please investigate whether any changes or issues were introduced in the WebSocket market data feed from 8 June onward?

      We can provide the complete raw data and additional instrument samples if required.

      Regards
