Backhand entrustment: close the position first, and then open the position in reverse.

Market backhand? My software is "fast backhand", which is the same as backhand commission, but faster.

For example,

You used to hold 1 hand soybeans.

Quick Lock: Open an empty order for 1 lot of soybeans at the current price immediately, so that orders can be placed in two directions at the same time. No matter how the price goes up or down, your profit (or loss) will be locked, which is the difference between these two orders, so it is called locking. When the direction is unknown, lock the warehouse first, at least it will not expand the loss.

Backhand entrustment: If you feel that it is going to fall now, immediately close multiple orders and open 1 empty orders in reverse. At this time, you have a 1 statement in your hand.

Market backhand: Same as above, but faster.
