First, you don't know the concept of the number of futures contracts. The unit of futures trading rapeseed meal is 10 ton! That is to say, if the margin you need to open the third hand is 30× margin percentage× 2500, assuming that your margin amount at that time is 15%, then the result is 1 1250, and basically the rest of the funds cannot be opened.

Second, the so-called penetration of positions. Breaking a warehouse doesn't mean that you open some contracts and deal with warehouse receipts at a loss. The short position can only explain one problem, that is, your margin is not enough for your current position, and the risk has already occurred! There is a certain risk control coefficient about short positions. When the short position reaches a certain level, the futures company will take certain risk control measures, which is called forced liquidation. In fact, the futures company will not let you overstock. They will help you solve all the orders before going to the warehouse, because they don't want to post the money themselves!
