编空心红三角和实心红三角的公式

编写要求：

源码： DING:=MAX(O,C);{实顶} DI:=MIN(O,C);{实底} YANG:=(DI>=REF(DING,1)) OR (C>O AND NOT(DING<=REF(DI,1))) OR (C>REF(C,1) AND C=O) OR (C=REF(C,1) AND C=O AND REF(DING,1)=C);{阳线} YIN:=NOT(YANG); {YIN:=(C=REF(DING,1))) OR (C>O AND DING<=REF(DI,1)) OR (C=REF(DING,BARSLAST(YIN)) AND (V>REF(V,BARSLAST(YIN)) OR (BETWEEN(V,REF(V,BARSLAST(YIN))*0.975,REF(V,BARSLAST(YIN))*1.025))),NODRAW; DRAWTEXT(YANGSHENG AND REF(NOT(YANGSHENG),1),L*0.99,'△'),COLORRED; DRAWTEXT(YANGSHENG AND REF(NOT(YANGSHENG),1) AND VREF(V,BARSLAST(YANG))); DRAWTEXT(YINSHENG AND REF(NOT(YINSHENG),1),H*1.02,'▽'),COLORGREEN;

解答：

?DING:=MAX(O,C);{实顶}

DI:=MIN(O,C);{实底}
