LC:=REF(CLOSE,1);
rsi1:=SMA(MAX(CLOSE-LC,0),6,1)/SMA(ABS(CLOSE-LC),6,1)*100;
RSI2:=SMA(MAX(CLOSE-LC,0),12,1)/SMA(ABS(CLOSE-LC),12,1)*100;
RSI3:=SMA(MAX(CLOSE-LC,0),24,1)/SMA(ABS(CLOSE-LC),24,1)*100;
crOSS(RSI1,RSI2) AND CROSS(RSI2,RSI3)AND CROSS(RSI1,RSI3);
====================
{周线金叉}
CROSS("RSI.RSI1#WEEK","RSI.RSI2#WEEK") AND CROSS("RSI.RSI1#WEEK","RSI.RSI3#WEEK")AND CROSS("RSI.RSI2#WEEK","RSI.RSI3#WEEK");
====================
{月线金叉}
CROSS("RSI.RSI1#MONTH","RSI.RSI2#MONTH") AND CROSS("RSI.RSI1#MONTH","RSI.RSI3#MONTH")AND CROSS("RSI.RSI2#MONTH","RSI.RSI3#MONTH");
