For example, suppose a customer has 165438+ 10,000 yuan, the stock index futures margin collection ratio is 1 1%, and there are 10 empty orders in Man Cang at 3300 points of stock index futures, then the margin collected by the futures company is 3300× 300×/kloc-0. At this time, the customer risk of the futures company is108.9/10 = 99% (sometimes called the customer's futures company risk). Correspondingly, the customer risk calculated according to the margin ratio of the exchange is 3300× 300×10 %×1. When the market rises by 34 points, that is, to 3,334 points, the occupancy margin is 3,334× 300×10 %×10 =10.02 million yuan, and the customer's equity is10-34× 300. At this point, the customer entered a strong and flat state.

So, is 10 flat or flat? The general practice of futures companies is to balance the available funds to be positive, and the above customers need to balance 1 positions to release the margin. Under normal circumstances, even if the futures company reaches the strong level line on the same day, if the risk assessed by the futures company is not great, the futures company may not be strong level on the first day, but if the exchange risk is greater than 100% on the second day, the futures company will definitely be strong level, because it involves the problem of regulatory deduction.
