$RIVER Haha, the market change speed exceeds my expectations. After waking up, the lowest price of river@E5@ dropped from 30 to 20.5. Actually, before sleeping, @E5@ was at 28, and the big players didn't push it up, but instead started to unload.

After paying the fees and with a light position, I didn't lose much. It looks like another buying opportunity here. Although the position size has halved (price dropped about 1/3, and the holding volume decreased by 50%-70%), the gap between the big players' long and short positions is no longer that large. If I don't buy, then shorting could realize profits.
