$HSC RESOURCES (01850.HK)$ Why is it going down even though ...

182453466 : I saw it yesterday, and it looks like it's a way to sell 10000 and buy 9990

banana fish OP 182453466 : I wonder if it's a short sale and buy it back

Margin is low, but if it's a big deal, you can make a reasonable amount of money

Renren2 : The situation of major securities firms is certainly underselling, but from the aggressive trading status that includes these, I think it's still a trend with a dominant sales trend. Maybe my understanding is wrong.

banana fish OP Renren2 : That's true, but the number of shares in a securities company doesn't match the number of shares on the pie chart

The more different the digits

I wonder if it's a situation where securities companies are selling all at once and aren't going around, for now

Renren2 banana fish OP : Thank you very much for teaching me. I thought it was completely correct to point out that securities companies weren't selling. As far as I understand the chart, what is traded by a major securities company is the deal that that company buys and sells with its own funds, and I was wondering if the pie chart below is the overall active trading status, including brokerage operations where individuals buy and sell through securities companies, but my understanding is shallow and I'm not sure.
