$ETH

Ether has only a few positions

Just go to where you want to go and do it

The only thing to pay attention to is the freshness of the position and the consumption of orders

If the position is not fresh, then act on the right side

PS: I know you will say that you don’t understand what freshness is. I have posted a technical video on freshness. If you search it yourself, you can’t find any bloggers talking about this knowledge point on Du or Audio. Then, I also have technical posts on support and pressure. You can do it yourself and you won’t suffer any loss. These basic things will be interspersed in every live video, and the book is more comprehensive.
