Foreign exchange speculation is not like stock speculation. No matter how it falls, as long as that stock doesn't withdraw from the market, the funds you invested will not be completely lost, and it will not affect the idle funds in your account. Foreign exchange is different. Once the foreign exchange is chosen in the wrong direction, you will lose not only the funds you bought, but also the unused funds in your own account. When you know that your funds are almost lost, there will be short positions and the system will automatically close the positions. So this is also why many foreign exchange operators will strictly implement their own stop-loss positions. Otherwise, the direction is wrong, plus the unilateral market, there will be short positions.
I once read a report that a foreign exchange player has been bearish on RMB, so he has been shorting RMB, but it happened that RMB has been rising since 20 17, so his tens of millions of dollars exploded in continuous losses.
