On May 16, the order of 0.16 was placed after a loss of fifty or sixty dollars, and the order of 0.17 was placed after 40 minutes. This led to two more orders in this wave of orders. The first wave could not close the position, the second wave and the third wave could not be closed, resulting in a sharp rise in the market. On the 2nd and 17th, the loss was seven or eight thousand dollars.
