[Andrew: Are you able to add columns part way though an exploration? I
can't seem to.}
Andrew, I seem to recall this problem in another application and I solved it
by keeping the number and length of columns constant and just putting zeroes
or null or make them black when i don't need them. How would you display
partial columns? Say, column one for 50 stocks, the next for 30 stocks, etc.
I think you have no choice but keep the columns of equal length and showing
NULL (empty) cells where you should have no data.
Addtional status() at the start and end of an Exploration have been
suggested and will probably be added one day, meanwhile there are some
work-arounds.
good luck,
herman.

Thanks for the example, one thing I'm having trouble with though is this
part of your example
>else if(Task==3 AND Status("StockNum")==NumTickers)
> {
> // Do something during the last ticker in the WL
> AddColumn(Status("StockNum"),"StkNum",1.0,1,colorGreen);

I never have this column added unless I somehow initiated it when
Status("StockNum")==0 .
Are you able to add columns part way though an exploration? I can't seem
to.
Thanks
Andrew
Ps. Never taken the time to thank you for your HBT3A pluggin. I use it all
the time but only as a substitute for a MA. Do you have any other
applications for it? I notice you can vary the values of arguments 2 & 3, so
I guess adaptive Smoothing procedures are possible.
