{预警1}
N:=42;
N1:=21;
WR1:=100*(HHV(HIGH,N)-CLOSE)/(HHV(HIGH,N)-LLV(LOW,N));
WR2:=100*(HHV(HIGH,N1)-CLOSE)/(HHV(HIGH,N1)-LLV(LOW,N1));
激进买点: CROSS(50,WR1) AND CROSS(50,WR2);

{预警2}
N:=42;
N1:=21;
WR1:=100*(HHV(HIGH,N)-CLOSE)/(HHV(HIGH,N)-LLV(LOW,N));
WR2:=100*(HHV(HIGH,N1)-CLOSE)/(HHV(HIGH,N1)-LLV(LOW,N1));
稳健买点: CROSS(20,WR1) AND CROSS(20,WR2) AND WR1>0 AND WR2>0;
