I’m observing the issue constantly, particularly on Sensex options instrument. Here is another example:
Instrument: 81400 CE
Trade Date: 12-Sep-2025
Expiry: 18-Sep-2025
uts → currentTs of the payload (i’m calling as upstoxTimeStamp)
Also illustrating what could be the potential problem (current behaviour in above pic):
CT → currentTs, LT → lastTradedTime
CT1 is carrying LT2 tick and CT2 carrying LT1 tick, which seems problem.
The expected result should have been as shown in expected behaviour in the above pic.
