There are three main reasons for the forced liquidation of investors on mt4 platform: First, the forced liquidation is caused by the explosion of positions. This is the most common reason why the mt4 platform was forced to close its position. When the exchange rate fluctuates sharply, the remaining margin in the account is not enough to support the risk and will be forced to close the position. Simply put, if the money in your account is gone, you will be forced to close your position. The second is the forced liquidation caused by the expiration of the contract. This situation is only for futures products, such as crude oil, natural gas, Bund, copper and other products. These futures products have specific delivery dates. If they don't close their positions within the delivery date, they will be forced to close their positions at maturity. Third, because the stop loss was forced to close the position. This is easy to understand. When using mt4 to make orders, take profit and stop loss will be set to control risks. When the exchange rate fluctuates to take profit or stop loss, it will forcibly close the position.
