A short position in stock index futures means that the loss is greater than the margin in your account. After the company is leveled, the remaining funds are the losses deducted from the total funds, and generally there is a part left. It is understood that usually after overdraft investment, the loss exceeds its own funds.

The way to avoid warehouse explosion is to order a small amount of warehouses to keep the water flowing. For example, there are 65,438+00,000 US dollars, 65,438+00 times leverage and 65,438+0 maximum positions, so the anti-risk ability is more than 900 points and the risk degree is about 65,438+00%. If you use the lever of 100 times to open a heavy position, the anti-risk ability will be less than 100 and the risk degree will be greater than 90%. Just like today's pound, it will be blown up by the surge of 100.
