I am also an experienced programmer of many years. Too many probably.
I have worked with many languages and assembler, but mostly with
structures where the power was in the code not the language. So what
you saw on the page told you what was going on. Mostly.
The real problem I have is the constant battle with array type, and
the refusal to allow the simplest comparisons.
Heres an example
WeeksBack = Param("Weeks Back", 52, 1, 520, 1 );
HighOrLow ="";
H1 = High > Ref(HHV(High,WeeksBack*7),-1);
L1 = Low < Ref(LLV(Low,WeeksBack*7),-1);
if (H1==1)
HighOrLow = "H";
if (L1==1)
HighOrLow = "L";
Filter = H1 OR L1;
AddTextColumn( FullName(), "Full name", 77);
AddColumn(H1 ,"High",3);
AddColumn(L1 ,"Low",3);
AddColumn(Close,"Close",1.4);
AddColumn(Volume,"Volume",1.0);
The problem is , AFL will not let me test for
H1==1 or H1==TRUE, complaining that H1 is an array. I tried a number
of things to convert it to a non array, but failed.
When you output H1 in a column, it is a 1 or a 0.
This is the 'nastiness' I referred to. I'm sure theres a solution,
and probably an easy one, but it is non obvious to me.
