Problem with the new indicator

[scyche]

I am only a starter and I was trying to create a strategy to generate buy and sell signals when the RSI and price trends are divergent from each other. But there's no action when I backtested it. Can anyone help me to check the code?

protected override void Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Test"));
CalculateOnBarClose = true;
Overlay = true;
PriceTypeSupported = true;

tops = new int[50];


}





protected override void OnBarUpdate()
{

for(i=n;i>=0;i--)
{
if(RSI(14,3)[i+1]-RSI(14,3)[i+2]>=0&&RSI(14,3)[i+1]-RSI(14,3)[i]>=0)
{
tops[j]=i+1;
if(RSI(14,3)[i+1]>RSI(14,3)[date])
{
date=tops[j];
m=j;
}
j++;
}
}
if(date == 1)
{
for(k=0;k<=m;k++)
{
if(Slope(RSI(14,3), tops[k], date)>temp1)
{
temp1=Slope(RSI(14,3), tops[k], date);
date2=tops[k];
}
}
if(Close[date2]>Close[date])
EnterLong(DefaultQuantity, "");
}

else
{
temp2=Slope(RSI(14,3), date, tops[m-1]);
for(l=m-1;l>=0;l--)
{
if(Slope(RSI(14,3), date, tops[l])>temp2)
{
temp2=Slope(RSI(14,3), date, tops[l]);
date3=tops[l];
}
}
if(Close[date3]==1&&Close[date3]>Close[date])
{
ExitLong();
}

}

Thank you very much!

scyche,

Welcome to the NinjaTrader Support Forums. Please check your Control Center logs for errors. Anything suspicious? If there are no errors you will need to step through your code slowly and find what is actually happening through your loops. http://www.ninjatrader-support2.com/...ead.php?t=3418

Thank you. I have checked the log. It says:"Error on calling the 'OnBarUpdate' method for strategy 'result':Index was out of range. Must be non-negative and less than the size of the collection."

But I don't quite understand what does this mean. Would you please interpret that to some kind of simple language to me?

Thanks again.

It means you are accessing an index value that does not exist. Likely coming from your loops. You can only access values that currently exist. Please see this tip on making sure you have enough bars for data points: http://www.ninjatrader-support2.com/...ead.php?t=3170

Thank you!

Now I met a new problem after solving the previous one. In the log, it is said:"Error on calling 'OnBarUpdate' method for strategy 'result':Index was outside the bounds of the array." Would you mind translating this to me? I do appreciate your help!

Same thing scythe. You can ONLY access values that exist. You need to ensure all your arrays are only accessing valid indexes. Your use of loops can very easily try to access data points that just don't exist.

Thank you very much for your patience!! I got it!
