Silver OptionS Trading

Hi…I usually trade bank nifty options but I have some confusion about Commodity options.
My questions are:-
Currently, Silver is around 48000 and wants to buy 48000 June PE @1400.

  1. The amount required for buying 1 Lot of Silver,
  2. Do I need to pay extra margin other than the premium
  3. Can I have more losses other than the premium paid?
  4. how to find the expiration date for commodity options?

Silver lot size is 30 so the amount required for buying 1 Lot of Silver will be LTP*30

No and No.

You can find expiry in Market Watch on Kite.
