编写要求：

理想论坛里找到的通达信公式请老师改成飞狐和大智慧的精确买卖波段（通达信 源码）A7:=C-REF(C,1);A8:=100*EMA(EMA(A7,6),6)/EMA(EMA(ABS(A7),6),6);SHORT:=7; LONG:=19;RMA:=EMA(CLOSE,SHORT);NMA:=EMA(CLOSE,LONG);UP:DRAWLINE(L=LLV(L,BARSLAST(CROSS(NMA,RMA))+1),LLV(L,BARSLAST(CROSS(NMA,RMA))+1),H=HHV(H,BARSLAST(CROSS(RMA,NMA))+1),HHV(H,BARSLAST(CROSS(RMA,NMA))+1),0);DOWN:DRAWLINE(H=HHV(H,BARSLAST(CROSS(RMA,NMA))+1),HHV(H,BARSLAST(CROSS(RMA,NMA))+1),L=LLV(L,BARSLAST(CROSS(NMA,RMA))+1),LLV(L,BARSLAST(CROSS(NMA,RMA))+1),0);买进:(LLV(A8,2)=LLV(A8,7) AND COUNT(A8<0,2) AND CROSS(A8,MA(A8,2))) AND REF(DOWN,1)REF(DOWN,1);趋势区:=IF((EVERY(DOWN>=REF(DOWN,1),1)),4,2)COLOR0000FF,LINETHICK3;低买:IF(((CROSS(趋势区,2.1))),5,0),STICK,COLORRED,LINETHICK3;高卖:IF(((CROSS(3.9,趋势区))),-5,0),STICK,COLORFF9150,LINETHICK3;

解答：

A7:=C-REF(C,1);
