The cause of the warehouse incident is very complicated, but the root cause is the management of customer funds. At present, the Shanghai and Shenzhen 300 index futures margin collection standard is exchange 10%, and futures companies charge at least 2 percentage points, namely 12%. If the customer sells at the settlement price in Man Cang the day before, and loses 83.33% after the daily limit, and rises 2% the next day, it will be broken. 1) Sometimes customers have heavy positions, and they will choose another position besides opening positions in futures companies.

At present, the main force in the market is often to open positions in two directions, that is, to buy in one position and sell in another. Every day, they use the characteristics of heavy retail positions to suppress or pull up. When the retail position triggers a strong flat point and is forced to stop loss or a strong flat point, the main force operates in the opposite direction to earn the difference. In this way, the retail investors were beaten around by the main force, and the money was earned by the main force little by little. But sometimes people are not as good as the sky, and the market closes soon after opening every other day. The main position in a futures company can't stop loss, resulting in huge losses, while the position in another futures company makes a big profit. If the position is closed again the next day, from the most favorable point of view, the customer will of course choose to give up the loss position, hold or cash out the profit position, and at the same time file a lawsuit with the futures company in the loss account, asking the futures company to fulfill the obligation and responsibility of compulsory liquidation and compensate for the losses beyond its strong equilibrium point.

2) Customers abandon warehouses sometimes because of the violation of regulations by relevant personnel within the company.

For example, when a customer's position triggers a strong leveling point, at the customer's request, if the employee who introduced the customer is in a key position (such as a risk control post and a settlement post), he may choose to maintain the customer's unbalanced position for his own benefit. At this time, the customer margin may be only 30%, even lower than the position margin. If the market runs in reverse soon, it will be fine, but if it continues to fluctuate in the direction that is unfavorable to the customer's position, it will be easy to close the position. Customers generally choose to give up their positions and let futures companies dispose of them.

According to Article 32 of the Supreme People's Court's Provisions on Several Issues Concerning the Trial of Futures Dispute Cases, "If the customer's trading margin is insufficient and the futures company fails to notify the customer of the additional margin as agreed, the futures company shall bear the main liability for the enlarged loss caused by the customer's overdraft due to adverse changes in market position, and the compensation amount shall not exceed 80% of the loss." It can be seen that judicial interpretation is unfavorable to futures companies, and employees should be cautious about customers' pursuit of insurance.
