Not the best place to use loops, Kevin.
Do you really want to mix arrays and array elements?
1-Using Pos[i], requires working with H[i] and L[i] and calcing HHV and LLV
in inner loops.
2-Your type mismatch can be fixed by using Pos.
---------
Filter=1; i=1; Pos=1;
Period = EndValue(BarIndex())-BeginValue(BarIndex())+1; //useless
while( i < Period)
{
Pos=IIf(H>Ref(HHV(H,15),-1),1,
IIf(L<Ref(LLV(L,15),-1),-1,Pos[i-1]));
i=i+1;
}
AddColumn(Pos, "POS", 1.4 );
--------
3-Why not throw out the useless while loop?
---
Filter=1;
Pos=IIf(H>Ref(HHV(H,15),-1),1,
IIf(L<Ref(LLV(L,15),-1),-1,Pos[i-1]));
AddColumn(Pos, "POS", 1.4 );

Subject: [amibroker] More Array Processing for Newbies
I'm planning to write my own backtesting routine via the Explore, so that I
can generate the trade statistics that I want. (ie. normalized returns,
Optimal F, etc.)
But I have to understand the fine art of writing loops. This is a loop to
establish a position, that isn't working. Can anybody please help?
Filter=1;
Period = EndValue( BarIndex() ) - BeginValue( BarIndex() )+1;
i=1;
Pos[0]=1;
while( i < Period) {Pos[i]=IIf(H>Ref(HHV(H,15),-1),1,
IIf(L<Ref(LLV(L,15),-1),-1,Pos[i-1])); i=i+1;}
AddColumn(Pos, "POS", 1.4 );
Thanks
