It was a pity that NND started shorting at 106 and held it down to 116 for ten thousand points. When I saw it around 114 at around 4 o'clock, it started to turn around. I thought the bears had mostly cleaned up, and there was no reason to push it up again, so I went back to sleep. When I woke up, my position was gone. I kept averaging down and ended up losing all my principal. Holding onto positions is harmful.
