要求：1.看看有无未来函数（出来的信号会不会漂移）。2.如果没有未来 请将“底”做个选股预警.源码如下：牛熊线:=0;A:=EMA(CLOSE,13);LC:=REF(CLOSE,1);RSI1:=SMA(MAX(CLOSE-LC,0),6,1)/SMA(ABS(CLOSE-LC),6,1)*100;AR:=SUM(HIGH-OPEN,26)/SUM(OPEN-LOW,26)*100;卖点雷达:CROSS(85,RSI1)*30;DRAWTEXT(CROSS(85,RSI1),80,'顶');VARB:=SMA(MAX(CLOSE-LC,0),7,1)/SMA(ABS(CLOSE-LC),7,1)*100;VARC:=SMA(MAX(CLOSE-LC,0),13,1)/SMA(ABS(CLOSE-LC),13,1)*100;VARD:=BARSCOUNT(CLOSE);买点雷达:(VARB< 20> 50 AND AR<70 AND VOL编写条件：
