4/5 The problem is in the picture

I think it has not fallen to the stage target yet. This may just be a rebound. It will rebound to around 15 and then continue to fall. It will eventually fall to 10.6, which is the previous low on the left, and oscillate in a large range during the decline.

If you can't stand this daily K fluctuation, stop loss when it falls below the 13 area, and then see if the 10.6 area below can hold up before re-entering.
