Okay, this puzzle is solved.
I went back to early Oct with the 30 minutes chart. I see the WSAD was increasing, the price was increasing too, the money flow has been decreasing like this week. Eventually, it leads to the big fall for YM from 10430s to 10220s in a few days.
The Money Flow indicator is much better in predicting the future price movements.
