Advice for brothers with pending orders and filled orders:

I hope that after you place orders and when you receive filled orders, you can leave a message to let me know your current situation with placing and receiving orders, because the market is constantly changing. If you don't tell me, I have no way of knowing what's happening, and I can't give you appropriate and reasonable advice. Sometimes, losses on certain orders can be avoided.

Also, with recent market conditions, it's either going up or down sharply, with quite large fluctuations that are hard to control. So we need to communicate at all times to avoid unnecessary losses.
