If you are a retail investor, you have to make up the relevant funds first (you only paid a part of the deposit when trading), and then you can get the real thing (the contract text of Shanghai Futures Exchange stipulates that the rebar futures contract is delivered in kind), otherwise it will be regarded as a breach of contract and will be punished for breach of contract. It is ok not to take it, but it seems that there will be related storage fees (this aspect is not clear). It is recommended that you do not intend to close your position on the last trading day. Generally speaking, these commodity futures are mainly speculative long-term contracts. Generally, the closer the contract in recent months is to the delivery month, the less the transaction volume and the fewer entrusted transactions, so it is difficult for you to find a suitable counterparty to close the position. Generally, the operation of commodity futures is mainly on the main contract of this variety (the variety with the largest trading volume in the delivery month on that day will generally last for a certain period of time, so pay attention to the changes of related positions, and different futures varieties will have different specific conditions, mainly affected by the changes of related seasonal demand), and the operation of changing months and positions will be carried out at the corresponding time (this depends on the changes of related trading volume, and the trading volume will change obviously if it is about to become the main contract variety in the process of changing months and positions).
