Re: Referring to the status of the trade in system tester

["Gerard Jeuken" <gjeuken@xxxxxx>]

David , Ton,
The way of programming you suggested really results in more structured code.
I elaborated around in that way and it learns me I really have a circular
reference in the code.
What a wanted to do is , using a variable as  a "global variable " similar
as in Visual Basic, Delphi/Pascal ,   recursively accessible from any
subcode in the program .

It seems not to be allowed in MS-language (I wonder why not), so I think a
have to find ways to program around to get the desired results .

Thanks for your contributions,

Gerard

If({bullish} C > Mov(c,5,s)=1 {thus IS one and positive in your SysTst},
   {then do} +1 {=TRUE for SysTst},
   {else and false do 0 (eg negative) or do another (nested) condition}
  If({bearish} C < Mov(c,5,s)=1 {thus IS one and negative in your SysTst},
     {then do} 0 {=FALSE for SysTst},
     {else and false, do 0 (eg negative) or do another (nested) condition}
     PREV
