Init:=Cum(IsDefined(RoaR))=2;
Steve, the Init variable above holds an initialization signal when the
RoaR plot has been defined/valid (i.e., not N/A) for two bars. This
initialization/seeding is necessary because the BarsSince() conditions
create null (N/A) bars prior to the first crossover reference signal.
So, why not "Init:=Cum(IsDefined(RoaR))=1;" instead?
Because the Cross() function adds a null bar and would miss that first
initialization signal.
Creates/adds null bars? It sounds like "creating a void or vacuum".
Doesn't sound right but hopefully you get my meaning.
