请东方老师帮改选股公式

股民老张

DRAWTEXT_FIX(1,0.6,0.965,1,'老鼠打洞'),COLORYELLOW;
DRAWTEXT_FIX(1,0.3,0.875,1,'第一防线'),COLORYELLOW;
DRAWTEXT_FIX(1,0.3,0.75,1,'第二防线'),COLORYELLOW;

DRAWTEXT_FIX(1,0.3,0.375,1,'第五防线'),COLORYELLOW;
DRAWTEXT_FIX(1,0.3,0.25,1,'第六防线'),COLORYELLOW;
DRAWTEXT_FIX(1,0.3,0.125,1,'第七防线'),COLORYELLOW;
