If you don't want to make delivery and just speculate in futures, then your above questions are wishful assumptions and have nothing to do with your own futures trading.
Now let me answer your first question. If you are self-employed, your empty order will be closed on the last trading day one month before the delivery month, because self-employed people are not qualified for delivery. If you are a legal person, holding an empty bill, but there are no goods, there are two solutions: 1 receiving spot delivery (a waste of time), and closing the position before the contract expires. If you still hold an empty bill without spot, isn't it quilt cover?
The second question: If you are self-employed, you will also be leveled. If it is a legal person, the standard warehouse receipt will only be issued when the goods are delivered nearby. With this warehouse receipt, you have the ownership of the delivered goods. You can take it away at any time, but you have to pay the fee to the warehouse.
Finally, I feel that the landlord is a little stubborn. Futures trading is nothing more than speculation, hedging and delivery.
To speculate, spend money on the main contract, analyze the market and follow the general trend.
Do hedging, according to their own spot situation, the corresponding hedging behavior of selling or buying.
To make delivery, it is necessary to prepare the goods or money for honest delivery.
It's tiring to type one word at a time.
