Hello,
> Wouldn't x be the exact value of z for the same bar as the first y==1? How
does that return an array? If so, how do I "iterate through the values"?
No. You can see the values by trying the code below. It returns a array
that includes the valuewhen result for every bar.
Use the following to iterate through this array:
for(i = 0; i < BarCount; i++)
{
Value = x[i];
}
y = C == HHV(C, 10);
z = C;
x = ValueWhen(y, z, 1);
Plot(x[BarCount-1], "value for any index", colorBrown, 1);
Plot(x, "x", 4, 1);
Plot(C, "C", 1, 128);

Subject: [amibroker] Re: Valuewhen issue
Thomas, could you explain this further please?
Using this example:
x = valuewhen(y, z, 1);
Wouldn't x be the exact value of z for the same bar as the first y==1? How
does that return an array? If so, how do I "iterate through the values"?
Thanks!
