请朋友看看自设的通达信BBI选股公式选不出来股票来 怎么回事？

Question

BBI:=(MA(CLOSE,3)+MA(CLOSE,6)+MA(CLOSE,12)+MA(CLOSE,24))/4;
QCST:=EXIST(C/REF(C,1)>1.055,60)>1;
ABS(REF(LOW,1)-REF(BBI,1))/BBI<0.01 AND BBI>=REF(BBI,1) AND QCST AND TOTALCAPITAL<9000000;
还有下面这个
BBI:=(MA(CLOSE,3)+MA(CLOSE,6)+MA(CLOSE,12)+MA(CLOSE,24))/4;
QCST:=EXIST(C/REF(C,1)>1.055,60)>1;
ABS(LOW-BBI)/BBI<0.01 AND BBI>=REF(BBI,1) AND QCST AND TOTALCAPITAL<9000000;
谢谢!

Answer 1

你先将公式做成副图的看看信号,认为都没问题了才做成选股的,你说选不出股来,那要看有不有什么股是符合条件的而没被选出来,还有的是选出来的却是不符合条件的,有这些情况主要是本机数据问题,因为公式你是经过副图验证没问题的,就不用怀疑公式了

改为：
BBI:=(MA(CLOSE,3)+MA(CLOSE,6)+MA(CLOSE,12)+MA(CLOSE,24))/4;
QCST:=EXIST(C/REF(C,1)>1.055,60);
ABS(REF(LOW,1)-REF(BBI,1))/BBI<0.01 AND BBI>=REF(BBI,1) AND QCST AND TOTALCAPITAL<9000000;
BBI:=(MA(CLOSE,3)+MA(CLOSE,6)+MA(CLOSE,12)+MA(CLOSE,24))/4;
QCST:=EXIST(C/REF(C,1)>1.055,60);
ABS(LOW-BBI)/BBI<0.01 AND BBI>=REF(BBI,1) AND QCST AND TOTALCAPITAL<9000000;本回答被提问者采纳
