[amibroker] Re: help with getting NUMBER from ARRAY

["DIMITRIS TSOKAKIS" <TSOKAKIS@xxxxxxxxx>]

index value index[i] can not be placed inside the [] because it may 
be out of range.
Your variable[i] may be a function of index[i] in the following sense

array=StochD(); 
for(i=0;i<BarCount;i++)
{
index[i]=array[i]^2;//index is a function of array
Variable[i]=sqrt(index[i]);//variable is a function of index
}
Plot(Variable,"",1,1);
Plot(sqrt(StochD()^2),"",4,8);
