trouble with indicator error

[mike82]

log says there is an overflow with the plot method

protected override void Initialize()
        {
            Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "CIndy1"));
            Add(new Line(Color.FromKnownColor(KnownColor.Lavender), 0.0, "Line"));
            CalculateOnBarClose    = true;
            Overlay                = false;
            PriceTypeSupported    = true;
        }

        /// <summary>
        /// Called on each bar update event (incoming tick)
        /// </summary>
        protected override void OnBarUpdate()
        {
            if (CurrentBar<(2*periodMax)) return;
            
            double[] AMDMR = new double[periodMax-periodMin+1];
            double sum = 0;
            
            for (int i=1;i<periodMax-PeriodMin+1;i++)
            {
                AMDMR[i]=Math.Abs(Momentum(Input,i)[0]/(MAX(High,i)[0]-MIN(Low,i)[0]));
                sum=sum+AMDMR[i]/(periodMax-periodMin);
                Print("AMDMR["+(i+periodMin)+"]="+AMDMR[i]);
                Print(sum);
            }
            Print(sum);
            CIndy1.Set(sum);
        }

mike82,

Check for division by zero? Suggest you break down the steps and try to find where the logic falls apart through Print()s and try-catch blocks.

[mike82]

the problem seems to only pertain to the sum bit

it went away when i added other code

or set the indicator to close[0]

i had print() in there from the start it always printed fine, but the plot would only show on the first few days of the chart then disappear when you scrolled to the right.
once it disappeared you had to reload the scripts on the chart (after you scrolled left) for them to show again.

[NinjaTrader_JoshP]

Look in your Control Center logs for errors. Your sum bit is doing a division. Please check for division by zero or any other types of illegal math operations.

periodMax-periodMin
are both input parameters they're not equal and therefore not zero (also sum prints to the output window just fine)

[NinjaTrader_JoshP]

You will need to check your Control Center for errors.

overflow error in the plot or onbarupdate methods

[NinjaTrader_JoshP]

You need to isolate the line causing the issues and address it. If you feel its the sum line, break it down and find the exact component and then remove the issue.

changing:
sum=sum+AMDMR[i]/(periodMax-periodMin);

to
sum=sum+(AMDMR[i]/(periodMax-periodMin));

seems to have fixed it
