Friends counterattack:

REF(C,2)<REF(O,2) AND REF(C,1)<REF(O,1) AND C/O>1.03 AND V/REF(V,1)>1.2;

Explain the meaning of the formula:

REF (C, 2) <REF (O, 2) two days before the close line

REF (C, 1) <REF (O, 1) the previous day close line (yesterday close line)

C / O> 1.03 today after rising 3%

V / REF (V, 1)> 1.2 Today volume 20%
