I tried the following code which is suppose to filter my stocks when
the short term ema is above the longer term ema for the last 30
days. However when I run it, it gives an error message saying I need
to define a NumColumn variable. I know how to add a new column but I
am not sure what the array needs to be. Can anyone help me get this
code working?
<==Start Code==>
st=ema(c,10);
>lt=ema(c,20);
>filter=sum(st>lt,30)==30;
<==End Code==>
Thanks,
Alan
