Attention ⚠️
The lower boundary of the three-day line is just a reference.
Don't think that it's safe when it rises to 90 over the weekend.
It's normal for it to drop four to five thousand points.
Refer to the last three-day line pullback at 565.
At that time, the lower boundary was at 602.
This is one of the commonly used methods.
The second method is to decline around the lower boundary.
Eventually, it will also drop four to five thousand points.
So 85 and 86 are also reasonable ranges.
That's all!
