Hi @Vedang_Sardessai, Welcome to MadeForTrade community.
We have this feature where you will be able to save the default order quantity / lot size for trading and specific to each Option Contract on Indices & Commodities.
With Pre-Set quantity (lot size) we have made available the feature to all tradeable F&O indices in options, like NIFTY50, BANK NIFTY, FINNIFTY, Natural Gas, Crude Oil, Gold, Silver contracts.
