What are your trying to do? HHV gives the value of the highest high
over the period you enter in x. If you want to find how far back that
is you can use
bs = BarsSince(H == HHV(H, 10));
// the next line prints the num bars back and the high of that bar
printf(NumToStr(bs, 1.0) + " High " + NumToStr(HHV(H, 10), 1.2));
If you want to find the value of the other things bs bars ago then
you can
// use the following. This applies to any array
lastHigh = ref(High, - bs);
// this is another way to see the results that shows the high value
Plot(lastHigh, "high bars ago", colorBlack);
Plot(Ref(C, -bs), "close bars ago", colorblue);
Plot(Ref(MA(C, 10), -bs), "MA(10) value bars ago", colorGreen);
// then look at what valuewhen returns
Plot(ValueWhen(H == HHV(H, 10), H, -1), "ValueWhen", colorRed);
bsolutely the last thing you want to do is start using loops, such as
for loops, to extract data from ABs arrays. Your code will be much
cleaner and faster if you use straight AFL.
Your terminology true value is confusing. The value in an array is
the true value. Do you mean what was the value when the condition was
true?
