/*An MACD, Signal Cross is, in general, a bullish Signal.
Since it comes with a significant delay, it would be important to anticipate this Cross. Some days before the Cross, we often see an MACD turning point. It is interesting to investigate the related conditions AND use them before the end of the session.
The following AFL code will give the necessary next ROC for a higher MACD value.*/

请教程式如何改 才能得到每日的nextROC1和nextROC2

SelectedValue的问题？

Plot (nextROC1,"nextROC1", colorRed) ;
Plot ( nextROC2 ,"nextROC2", colorGreen) ;

不行，一样的。只能得到两条直线

Title = "NextROC1 = "+nextroc1+"   NextROC2 = "+nextroc2;

Title = "NextROC1 = "+nextroc1+"   NextROC2 = "+nextroc2;

只能显示当日的数据 见图

把 SelectedValue去掉試試看唷~~

hangye 發表於 14-5-17 21:19

还是不行唷，大大
