#TA The market maker has a lot of chips. If you have a Heavy Position, do you want to be a little market maker? Do you have the funds to handle it? If you all have Heavy Positions, do you believe they will directly dump on you?
So it's still more cost-effective to short from a high position, because once it's high, after all, you have to sell to make a profit. Coming down like a waterfall, it's much more enjoyable to make money.
