Locking only appears in the investment of two-way trading mechanism. Locking is to lock the current profit and loss. No matter how the market fluctuates, you just lose the daily overnight fee, which is an operation method to avoid risks.

For example, many orders were placed for crude oil at $50, and then the price dropped to $49. If the price is expected to continue to fall, or the direction is uncertain, but the general direction is bullish, you can lock the order, set an empty order at $49, and release it one by one at the right time.

Tip: unlocking is a complicated process. If you are not sure, it is recommended to leave directly and then make the next order.

Locking has nothing to do with the product itself, but with the trading mode. Locking can only be operated in two directions, so whether it is silver, crude oil or asphalt, it can be locked as long as it is an over-the-counter trading mechanism.
