编写要求：

公式如下: DRAWTEXTREL( 0,100,'指标用法:八条横线代表八个指标,当天有四个以上红箭头为多头,反之为空头' ),ColorFFAA00; 100,PRECIS0; DIFF:=EMA(CLOSE,6)-EMA(CLOSE,8); DEA:=EMA(DIFF,3); MCDA金叉:DIFF>DEA,LINETHICK0,PRECIS0; DRAWTEXT(DIFF>DEA,80,'▲'),colorRED,linethick1; DRAWTEXT(DIFFD,LINETHICK0,PRECIS0; DRAWTEXT(K>D,70,'▲'),colorRED,linethick1; DRAWTEXT(KRSI2,LINETHICK0,PRECIS0; DRAWTEXT(RSI1>RSI2,60,'▲'),colorRED,linethick1; DRAWTEXT(RSI1LWR2,LINETHICK0,PRECIS0; DRAWTEXT(LWR1>LWR2,50,'▲'),colorRED,linethick1; DRAWTEXT(LWR1BBI,LINETHICK0,PRECIS0; DRAWTEXT(CLOSE>BBI,40,'▲'),colorRED,linethick1; DRAWTEXT(CLOSEMMM,LINETHICK0,PRECIS0; DRAWTEXT(MMS>MMM,30,'▲'),colorRED,linethick1; DRAWTEXT(MMSDDX2,LINETHICK0,PRECIS0; DRAWTEXT(DDX1>DDX2,20,'▲'),colorRED,linethick1; DRAWTEXT(DDX1OPEN,VAR1*(HIGH-LOW),IF(CLOSEOPEN,0-VAR1*((HIGH-CLOSE)+(OPEN-LOW)),IF(CLOSEDLX2,LINETHICK0,PRECIS0; DRAWTEXT(DLX1>DLX2,10,'▲'),colorRED,linethick1; DRAWTEXT(DLX1

解答：

?DIFF:=EMA(CLOSE,6)-EMA(CLOSE,8);

DEA:=EMA(DIFF,3);
