在主图中只显示当天的融胜轨道线

源码是融胜轨道的晴天老师的版本： DD:=DMA(CLOSE,ABS((2*CLOSE+HIGH+LOW)/4-MA(CLOSE,20))/MA(CLOSE,20)); 融上:(1+7/100)*DD,COLORYELLOW; 融下:(1-7/100)*DD,COLORYELLOW; 融中:(融上+融下)/2,COLORYELLOW; 晴上:(1+N/100)*DD,COLORGREEN,DOTLINE; 晴下:(1-N/100)*DD,COLORGREEN,DOTLINE; EPPP:=(HIGH+LOW+OPEN+2*CLOSE)/5; DRAWNUMBER(ISLASTBAR,融上,融上),COLOR00FFFF; DRAWNUMBER(ISLASTBAR,融下,融下),COLORFFFF00; DRAWNUMBER(ISLASTBAR,融中,融中),COLOR00FF00; DRAWNUMBER(ISLASTBAR,晴上,晴上),COLOR0000FF; DRAWNUMBER(ISLASTBAR,晴下,晴下),COLORWHITE; 希望修改成只显示当天的轨道线和价格，以前的轨道线不显示。
