Title: Re: [amibroker] Re: Consistent coding structure problem
just duplicate the code as often as is needed:
RU1_Check =
IIf( XYZ_Check == 0, Open>Ref(Open,-1) AND Open>Ref(Open,-2) AND Open>Ref(Open,-3),
IIf( XYZ_Check == 1, Open>Ref(Open,-2) AND Open>Ref(Open,-3) AND Open>Ref(Open,-4),
IIf( XYZ_Check == 2, Open>Ref(Open,-3) AND Open>Ref(Open,-4) AND Open>Ref(Open,-5),
IIf( XYZ_Check == 3, Open>Ref(Open,-4) AND Open>Ref(Open,-5) AND Open>Ref(Open,-6),
0))));
RU2_Check = // I didn't bother to change the definitions.
IIf( XYZ_Check == 0, Open>Ref(Open,-1) AND Open>Ref(Open,-2) AND Open>Ref(Open,-3),
IIf( XYZ_Check == 1, Open>Ref(Open,-2) AND Open>Ref(Open,-3) AND Open>Ref(Open,-4),
IIf( XYZ_Check == 2, Open>Ref(Open,-3) AND Open>Ref(Open,-4) AND Open>Ref(Open,-5),
IIf( XYZ_Check == 3, Open>Ref(Open,-4) AND Open>Ref(Open,-5) AND Open>Ref(Open,-6),
0))));
