On 12-Oct-2026, 14:16–14:22 IST, I subscribed 100 NSE_CM tokens in mode 4 across two connections. Every mode-4 packet for every token is byte-for-byte identical across the whole session, and bytes 27–34 decode to epoch ms 1746519636759 (06-May-2025 13:50:36 IST). Example: token 2885 (RELIANCE-EQ) depth shows best bid 1418.50 / ask 1418.60 while mode-3 SNAP_QUOTE on the same connection shows LTP 1156.10 with exchange timestamp 12-Oct-2026 14:16:52. About 30% of tokens show crossed books (best bid ≥ best ask) in the frozen data. Mode 3 data is live and correct. Can you check the Depth-20 service.
