Going long and short on the same foreign exchange variety at the same time is usually called locking positions. At present, most foreign exchange platforms support this operation. Lock warehouse generally has two situations:

1. When the profit is large, the price will face a callback, and the profit can be locked under the reverse order. When the callback is in place, the reverse order is even, and the original order can continue to be held.

2. In the case of a single loss, if the market is not very clear, you can lock the loss under the reverse order and unlock it when the market is clear.

However, locking warehouses requires considerable skill and is not recommended by novices.
