In many cases, the increase in warehouse receipts is bad news for the price, but it is in line with the overall macroeconomic and fundamental benefits. The increase of warehouse receipts can also be explained as active trading, which directly reflects the essential difference between supply and demand in the market at that time. The increase in warehouse receipts means that users should pay attention to the increase in the spot quantity of products in the market at this stage. The number of positions can reflect the attention of variety contracts to a certain extent, and the increase or decrease of positions is one of the signals of funds entering and leaving varieties. If the number of registered warehouse receipts decreases, it shows that the market demand for this type of products was high at that time.

Generally speaking, the increase of warehouse receipts is good for the whole market and bad for the price. The increase in warehouse receipts indicates that spot traders are preparing to sell goods in the futures market, and the price is higher, which is expected to go down in the afternoon. If the warehouse receipt increases after the futures price rises for a period of time, the probability of price weakening later is greater.

1. It is very simple to cancel the warehouse receipt, that is, if you put things in someone else's warehouse, there will be a certificate of deposit, called a warehouse receipt. Later, if the goods are pulled because of the delivery or the expiration of the warehouse receipt, then the warehouse receipt in your hand will be cancelled (so that the warehouse receipt in your hand will be taken back). The sharp increase in warehouse receipts may be due to the pessimism of the market on this variety of transactions. Traders think that arbitrage is profitable now and pull the goods to the warehouse for delivery.

2. The cancellation of warehouse receipts is also one of the important tools for the makers (or the main holders of warehouse receipts) involved in futures trading to manipulate the futures price trend. They mainly change the inventory quantity announced by the exchange by registering and canceling warehouse receipts.

Standard warehouse receipt refers to the physical delivery certificate issued by the delivery warehouse designated by the exchange to the shipper after being uniformly formulated by the exchange and confirmed to be qualified by the warehousing acceptance.

Making warehouse receipt is the process of converting the goods that meet the standard contract into standard warehouse receipt, which generally needs to go through delivery forecast, goods warehousing, acceptance, designated delivery warehouse issuance, exchange registration and other links.
