The lock function only exists in investments that can be traded in two directions, and is usually used to hedge open positions. If you don't click the lock order to hedge, you can directly place a reverse order in the same currency group on the opened position, which will result in a relative write-off with the original position. For example, there is already a euro/dollar payment position.

If you open another EUR/USD selling position, the related position will be automatically reversed.

The following is my experience in making orders at futures experts. com。

Method 1: first solve the contrarian list;

Method 2: Solve the income statement first. Of the above two methods, individuals prefer the first one. Because the purpose of our order is to prevent losses, when the market is clear, solving the contrarian order is equivalent to cutting off the source of losses. However, it should be noted that the contrarian order is not equal to the loss order. Another homeopathic list can choose the market to go almost flat. The second method is to make a profit first, and the other one can be even when it is called back or reversed. But callback and reversal involve the judgment of timing. If the other order is not leveled in time, it is likely to be converted into a medium-long line. Second, lock deadlock deadlock deadlock and lock death are actually not much different. The only difference is that when the account is locked, one is a loss and the other is a profit.

My personal suggestion is that it is better to take profits in time or follow up the mobile stop loss, because it is better to place an order after the market is clear. Because the profit is locked, it is relatively easier to solve and the psychological burden is much smaller. Having said that, the principle of solving a bill is actually similar to that of solving a loss bill. Because the two want similar results, one is to reduce losses and the other is to maximize profits. There is a saying in investment: reducing losses equals gaining gains!
