N1:=7;N2:=14;N3:=21;

LC:=REF(CLOSE,1);

RSI1:SMA(MAX(CLOSE-LC,0),N1,1)/SMA(ABS(CLOSE-LC),N1,1)*100,COLORFFFFFF;

RSI2:SMA(MAX(CLOSE-LC,0),N1,1)/SMA(ABS(CLOSE-LC),N1,1)*100,COLORFFFFFF;

RSI3:SMA(MAX(CLOSE-LC,0),N1,1)/SMA(ABS(CLOSE-LC),N1,1)*100,COLORFFFFFF;

RSI4:SMA(RSI3,7,1),LINETHICK2,COLOR00CD00;
