爱约股解答：

SHORT:=7;

LONG:=19;

RMA:=EMA(CLOSE,SHORT);

NMA:=EMA(CLOSE,LONG);

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);

趋势区:=IF((EVERY(DOWN>=REF(DOWN,1),1)),4,2);

低买:CROSS(趋势区,2.1);
