I was validating the data and find lot of instance across F&O instruments, where i see that between two ticks, the OI increases, but the volume doesn't.. eg: NIFTY FUTURES: oi: 18094875 volume: 8041125 Last Price: 10859.00 LTTS: 2019-09-05 12:35:27 oi: 18101100 volume: 8041125 Last Price: 10859.00 LTTS: 2019-09-05 12:35:27
And in some cases: Increase in OI doesn't reflect in volume. Increase in volume should be atleast equal or more than increase in the OI eg: RELIANCE oi: 57481000 volume: 13203000 Last Price: 1230.60 LTTS: 2019-09-06 13:11:26 oi: 57498500 volume: 13203500 Last Price: 1230.85 LTTS: 2019-09-06 13:11:35 Increase in OI is : 17500, but vol increase is just 500
Is there any explanation for this ? Or am I missing something here.
