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.

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.
