The so-called strong balance means that when you buy in the opposite direction, your margin is seriously insufficient due to a large number of losses. You haven't made up the margin on the next trading day, and the bank will consider closing the position for you and releasing some funds until your available funds are positive! What needs to be explained here is that when your risk (position margin/account balance) approaches 125%, the bank will consider giving you a strong balance. If you only owe a little money, you are not strong!

A short position means that the loss is greater than the margin in your account. After the company is forced to draw a tie, the remaining funds are the total funds MINUS your losses, and generally there will be a part left.

If short positions lead to losses, and they are caused by investors, investors need to make up for the losses, otherwise they will face legal recourse.

In order to avoid this situation, it is necessary to control positions in particular, manage funds reasonably, and avoid possible Man Cang operations in stock trading; And unlike stock trading, investors must track the stock index futures market in time. Therefore, stock index futures are not suitable for all investors. A short position means that after the margin is removed, the loss is greater than the available funds in the account.

There is basically no short position in China, and there are restrictions on the rise and fall in China. When the margin is maintained below, the futures company will automatically close the position.

In Hong Kong's Hang Seng Index futures, the Hang Seng Index is a four-hour trading system. The next day, there may be a big gap or gap, which will lead to the reversal of positions, and the position will explode as soon as it opens, or even be negative.

The negative number is the money owed to the futures company, because the futures brokerage company invests the money in the futures exchange in order to close the position of customers.

For example:

Before the opening of 1 1 in August, the customer did not pay the additional margin to the futures company. In September, the stock index futures contract fell by 90 points, and opened at 1060 and continued to fall. The futures brokerage company forced the liquidation of customers 15, and the transaction price was 1055.

In this way, the situation of this account is:

Profit and loss of liquidation on the same day = (1055-1150) ×15×100 =-142,500 yuan,

Handling fee =10×15 =150 yuan.

Actual rights and interests =124850-142500-150 =-17800 yuan.

That is, the customer owes the futures brokerage company 17800 yuan.
