Pivot formula in EMA

[roland_p71]

Hello,

why does that not works:

EMA5Piv = ema(5,(high()+low()+close())/3);
...
..
.
return new Array (yyy,xxx,EMA5Piv) ;

The EMA5Piv won't be displayed! I want the EMA Length 5 of the pivot point.
Is there any alternative to this code that works?

Thanks for response.

Best regards

In order for the ema() function to work the source needs to be a series (see the syntax at the linked article in the EFS KnowledgeBase). This can be a price series (ie high(), low(), volume(), etc) or a custom series created in a separate function or efs and called using either efsInternal() or efsExternal().
(high()+low()+close())/3 does not return a series but a value because when you process a series [as in the case of your expression] the result is a single value and not a series.
Anyhow there is already a wrapper function for the expression (high()+low()+close())/3 which is hlc3() and that returns a series
