老师画个背景框或者线框 (文华财经WH6赢顺V6.7)

 核实一下

DIFF先上穿0轴，再上穿DEA，则从MACD金叉向左画到DIFF上穿0轴，

高度是DIFF上0轴当根K线的最高价，到MACD金叉当根K线的最低价？

     1.DIFF先上穿0轴，再上穿DEA?

2.从MACD金叉向左画到DIFF上穿0轴?

3.高度是DIFF上0轴当根K线的最高价，到MACD金叉当根K线的最低价？

DIFF上穿DEA到上穿0

金叉向右画到上0轴，

高度的意思对

 参考：

DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26);
DEA:=EMA(DIFF,9);
JC:=CROSS(DIFF,DEA);
SC:=CROSSDOWN(DIFF,DEA);

COND:=CROSSDOWN(DIFF,0);
N1:=BARSLAST(SC)+1;
DRAWSL1(COND,L,0,N1-1,1),COLORGREEN;
DRAWSL1(COND,REF(H,N1-1),0,N1-1,1),COLORGREEN;

DRAWLINE3(COND,L,N1-1,COND,REF(H,N1-1),N1-1,0),COLORGREEN;
