What does volume for options mean mean in KITE charts

Hi,

how to interpret volume from kite charts ?

in the above chart screenshot for BN 19500 pe, volume is 120k,
what does it mean ?
1,20,000 lots of this options are bought or sold ?

@siva your inputs will really help me.

It is cumulative volume, which includes both trades on Buying side and trades on Selling side. It is the total quantity traded ie. Lots * Lot Size. You can learn more about Volumes here:

Thanks @ShubhS9

So, in the above example of 120k,
Is 60k lots bought & sold ?
or 3000 lots of lot size 20, got bought & sold ?

It’s total quantity traded. If you divide it by Bank Nifty’s lot size that counts for 6k lots bought and sold.
