求高手把一个通达信副图公式改为选股公式。条件是出现红色箭头。

N:=5;N1:=8;N2:=13;N3:=21;
LC := REF(CLOSE,1);
RSI1:SMA(MAX(CLOSE-LC,0),N1,1)/SMA(ABS(CLOSE-LC),N1,1)*100;
RSI2:SMA(MAX(CLOSE-LC,0),N2,1)/SMA(ABS(CLOSE-LC),N2,1)*100;
RSI3:SMA(MAX(CLOSE-LC,0),N3,1)/SMA(ABS(CLOSE-LC),N3,1)*100;
TY:=RSI1;{通用曲线值的引入}
AA:=REF(TY,N)=HHV(TY,2*N+1);
BB:=BACKSET(AA,N+1);
