Are you a coin standard or a U standard?
The operation strategies of different standards are different (there may be overlaps in some sections in the middle).
So, overall, this is a matter of having your cake and eating it too.
When it goes up, you use the coin standard, and when it goes down, you use the U standard. Usually you can only choose one. If you want both, it is very difficult, much more difficult than making money.
