RE: [EquisMetaStock Group] Re: Valuewhen()

["Andrew Tomlinson" <andrew_tomlinson@xxxxxxxxxxx>]

I use the ValueWhen(1+x,1,YY) formulation when I am using ValueWhen instead
of Ref().Using 1+1 instead of 2 reminds me that that is how I'm using
ValueWhen in this particular line of code, which is how Roy presents it in
his newsletter.

Thanks Jose , I had read through Roy's mail and Andrew's mail. I have some
confuse in one of the code :

BarDiff1:=ValueWhen(1,SignalIn OR Init,
   ValueWhen(1+1,1,BarsSince(SignalIn OR Init))+1);BarDiff1;  What is the
difference between ValueWhen(1,XX,YY) and ValueWhen(1+1,XX,YY).Could you
please explain about this. Thanks you very much.

Mun Wai.
