I think the following code will answer your questions. Put it in the
formula editor (or IB window if you are using ver. 4.60) and click
apply to make a plot. Use the code in the AA window and set the range
at 12/31/99 to present and run an Explore for the present symbol.
You will see that HHV makes an array because it has a different value
each day. What you want is the LastValue of HHV.
There are other ways to do debugging using the _TRACE() function, but
until you have a function to send the desired parts of arrays to
_TRACE(), it works best on single values, and the AA Exploration
method is probably the simplest way to display array values.
Good luck, Bill
// Code starts here
HiVal = HHV(C, BarsSince(DateNum()==991231) );
Plot(Close, "Close", 32);
Plot(HiVal, "HHV", 43);
Filter = 1;
AddColumn(HiVal, "HHV");
