Simply put, we trade futures or foreign exchange. If there is no money in the account, all the contracts we hold will be sold.
Generally speaking, strong leveling is a kind of risk control, and this level of risk is generally divided into three levels: chasing insurance, strong leveling and warehouse penetration. We know that futures and foreign exchange transactions are margin transactions, so in actual transactions, we pay a small amount of money to buy the whole commodity, and most of the money has been paid by the relevant companies on our behalf. Therefore, when the market fluctuates, when we lose our principal at a certain risk ratio, we will be chased; When it is close to the principal loss, it will be leveled; When we still owe money to the company after all the losses, we call it a warehouse. At this time, we still need to accept the company's recovery.
