九毛八公式指标
请老师编写一个通达信分时用的指标： 条件是：在昨日开盘价，昨日收盘价，昨日最高价，昨日最低价处画线。
公式模块：
先建名为1引用的指标，昨收就是当日的0轴
{1引用} 昨开:REF(O,1); 昨高:REF(H,1); 昨低:REF(L,1); 再建指标 昨开:"1引用.昨开#DAY"; 昨高:"1引用.昨高#DAY"; 昨低:"1引用.昨低#DAY"; 昨收:DYNAINFO(3); DRAWTEXT_FIX(CURRBARSCOUNT=1,0.01,0.01,0,STRCAT('昨高: ',CON2STR(昨高,2))),COLORYELLOW; DRAWTEXT_FIX(CURRBARSCOUNT=1,0.01,0.06,0,STRCAT('昨低: ',CON2STR(昨低,2))),COLORMAGENTA; DRAWTEXT_FIX(CURRBARSCOUNT=1,0.01,0.11,0,STRCAT('昨收: ',CON2STR(昨收,2))),COLORGREEN; DRAWTEXT_FIX(CURRBARSCOUNT=1,0.01,0.16,0,STRCAT('昨开: ',CON2STR(昨开,2))),COLORWHITE;
