Tick data has volume and oi 0.

Hi.
I am trying to check volume and oi in the tick itself but getting 0. The market is live as of now, and i tried on reliance equity and RELIANCE25AUG1420CE. Is this is a know issue?

Another question I have is that what is expected here - volume is todays traded volume and oi is today OI for the contract at that instance of the tick?


def on_tick(self, tick: KiteTick) -> None:
"""
Handle tick data

Parameters:
tick: Tick data
"""
#print("------------------------------------")
now = datetime.datetime.now()
#print(f"tick full data = {tick.__dict__}")
token = tick.instrument_token
print(f"tick data : {tick.__dict__}")
return


Output
