[amibroker] AdvIssues + DecIssues not working?

[Ed Cottrell]

Hello all,

 

I am trying to calculate the STIX indicator in an exploration using the
following code:

 

Period = 21;

Out_STIX = EMA(100 * AdvIssues()/( AdvIssues() + DecIssues() ), Period);

AddColumn(Out_STIX, "STIX");

 

AmiBroker says this is okay, but this isn't generating any output, at all,
regardless of which or how many stock symbols I run the exploration over.
Can anyone tell me what is wrong?

 

Thanks,

Ed
