Use of function

[letaxi]

Hi,
I am new to Ninja trader, and try to adapt my indicator from tradestation easy language to ninja script.
I would like to create a function lets say example
such as example[reference] = SMA(Close,Lenght)[reference]
that could be called into another indicator as for an example

if(CrossAbove(example[0],0.25))
indicator = 1;

But this has not been working for me, any thoughts anyone.
Regards

letaxi, welcome to our forums here - there would be no need to create subfunction in NinjaScript, any indicator would already per default expose a callable method - like the SMA(Close, Period)[bars ago] you cited.
