Help!! i have been struggling with arrays
Let's say that there are 100 bars
limit = Bars - counted_bars -1;
when counted_bars==0
limit=100-0-1
limit=99
for(i=Limite_Der_a_Izq_Final;i<limit;i++)The maximum value of i in the loop is
limit -1
99-1
98 is the maximum value of i
If there are 100 bars, the largest index is 99
Comment(RSI[i+2]); // it works with i and i+1, but i+2.... i+n it does not!!
So when the maximum value of i is reached in the loop
i=98
i+1=99
i+2=100
There is no index 100, so array out of range.
int counted = IndicatorCounted(); int lookback = ... // iMA(period) has look back of period. // buffer[i+2] has look back of 2 // use maximum of all. for(int iBar = Bars - 1 - MathMax(lookback, counted); iBar >= 0; --iBar) ...Always count down, repainting indicators are useless.
When you create an array that needs, let's say 10 spaces, you use the MyArray[10] when you create it. But computer programs start counting array indexes at 0, so for MyArray, the correct indexes would be 0-9, which is why Gum said limit-1. If you try using an index that is outside of that array's range, in this case, less than 0 or greater than 9, you get the error you are talking about.

Thank you very much!!

Hello i have been struggling with arrays, in this case i need to look to rsi in bar number 5,6 or 7 but it does a array out of rage, can you figure out what am i doing wrong,
Thanks.
Here is the code
--------
double RSI[];
extern int RSIPer = 14;//RSI Period
extern int Limite_Der_a_Izq_Inicial= 0;
extern int Limite_Der_a_Izq_Final= 0; // Real time
int counted_bars;
int limit;
int i;
int OnCalculate(const int rates_total,
const int prev_calculated,
const datetime &time[],
const double &open[],
const double &high[],
const double &low[],
const double &close[],
const long &tick_volume[],
const long &volume[],
const int &spread[])
{
counted_bars = IndicatorCounted();
ArrayResize(RSI,Bars);
if(counted_bars < 0) return(-1);
if(counted_bars > 0) counted_bars--;
if(Limite_Der_a_Izq_Inicial != 0)
{
limit = Limite_Der_a_Izq_Inicial;
}
else
{
limit = Bars - counted_bars -1;
}
for(i=Limite_Der_a_Izq_Final;i<limit;i++)
{
RSI[i] = iCustom(NULL,0,"RSI",0,i);
Comment(RSI[i+2]); // it works with i and i+1, but i+2.... i+n it does not!!
}
return(rates_total);
}
