Data in commodity (MCX) option chain volume is not correct

The total volume in the stock option chain appears to be accurate. However, the volume data for the commodity option chain seems incorrect. It is not possible for the volume to be less than the open interest change (OI change).
Additionally, if poosible

  1. Like oi (openInterestInLot, openInterest)the volume should also have both data (volumeInLot, volume) but volumeInLot is missing.

  2. Provide ChangeInLTP ( change of lastTradePrice from previous day)

The volume in the API response represents the volume per lot. We will include the lot-size volume as well. Additionally, we will provide the previous close price in the response.

if in the response volume is in lot then why for stocks same key gives value in per QTY.
it should be same across all exchange. Correct?
