If you can't get down, you can't just look at quantity and price. On the whole, the rise needs the cooperation of quantity and energy, and there is no quantity to go down. I haven't done much research on the basic principle of thread. The thread has fallen below the cost price, not that 3390 is an integer, but that 3400 is. I can't go down because other varieties have been falling for three days in a row and have stopped falling.
