For example, if you have five orders, now that you have bought five orders, you have no orders, and the rise and fall of futures has nothing to do with you.

For example, you have five orders to sell, and now you have bought five orders, which means that the warehouse receipt is locked, which is equivalent to no warehouse receipt. The rise and fall of futures basically has nothing to do with you.

However, if you are buying an open position, you actually have 10 lots, and you need to pay a deposit of 10 lots, and you will have to pay a handling fee for closing positions in the future.

Therefore, if you have an empty order and want to buy it, you should choose to close the position first.
