Hello

You don't need to write all these constants while creating the indicators in Forex Tester.
You just need to use the function Calculate.

procedure Calculate(index: integer); stdcall;

begin

// Here you should calculate values of

// index buffers for bar defined with "index"

...

end;

You can find more info in the Help -> Indicators API menu in the Forex tester program.
