“智能决策”

发一个主图公式“智能决策”，无未来函数。K:=(C+H+L)/3;
D:=MA(K,4);
操作:D,COLORWHITE,LINETHICK2;
拉升:HHV(D,13),COLORRED,LINETHICK2;
阻力:HHV(D,55),COLORRED;
买卖:LLV(D,8),COLORYELLOW,LINETHICK2;
顶部:HHV(H*0.98,55),COLORYELLOW;
DRAWTEXT(REF(C,1)>D AND C<D AND D>REF(D,1),H*1.02, '←卖出');
DRAWTEXT(REF(C,1)<D AND C>D AND D<REF(D,1),L*0.98, '←次日买'),COLORWHITE;
