How to apply functions to other than tickers?

[John Nelson <trader@xxxx>]

Is it possible to apply functions (which do not take arrays for 
parameters) to my own arrays of data? For example I would like to 
calculate the ADX of the OBV indicator... but ADX only looks at the 
current ticker symbol, not an input array.

So is there a way to do this, or do I have to duplicate the code for ADX 
in some way?

The intent is to discover when OBV turns over but without the delay of 
MA and without the ambiguity of Zig.
