1. Yesterday, the K-line with a long shadow line (the K-line shape with a shadow line twice larger than the entity and a short shadow line) rose or fell by less than 2%.

2. Today, the K-line with a long upper shadow line (the K-line shape with an upper shadow line twice larger than the entity and a shorter lower shadow line) rises or falls by less than 2%.

Long upper shadow: = ref ((min (close, open)-low)/(high-low), 1) > 0.667 and RANGE(REF(C, 1)/REF(C, 2), 0.98,1.

Long upper shadow: = (high-max (close, open))/(high-low) > 0.667 and RANGE(REF(C, 1)/REF(C, 2), 0.98,1.02);

XG: long lower shadow line and long upper shadow line;
