股友量

456.问:
       如何在指标上让0以下的线不显示出来
    答(股影):
       用条件函数IF(X,A,B)-------根据条件求不同的值。

       用法:IF(X,A,B)若X不为0则返回A,否则返回B.
       例如：
       A:=(C-MA(C,10))/MA(C,10)*100;{指标线}
       IF(A>0,A,0);

       {表示指标线A>0时显示A指标线，否则返回“ 0 ”}

457.问:
       帮我编写一个选股公式[大智慧].条件为股价与30天均线正负1%.
    答(大庆老杨):
       主图看信号位置：
       MA30:MA(C,30);
       DRAWICON(ABS(C/MA30-1)<0.01,L,1);

       选股：
       MA30:=MA(C,30);
       ABS(C/MA30-1)<0.01;

458.问:
       怎样编写预测当天成交量的指标和怎样计算前5天成交量和
    答(君俊):
       sum(c,5);//5daysvolume

459.问:
       编一公式：要求13日均线和macd同时加大
    答(股影):
       MA(C,13)>REF(MA(C,13),1) AND "MACD.MACD">REF("MACD.MACD",1);

460.问:
       编写当MACD柱变短时显示图标,上下箭头就是我所想要的

    答(君俊):
       参看中文先生的MACD实战源码（FH）
