custom indicator

[samjesse]

Hi

A custom indicator I built plots the correct line data on the screen but plots random values in the rest of the chart where I do not expect it to plot any thing.
How can this be fixed?

many thx

Do you initialize indicator plot with EMPTY_VALUE?

int OnInit()
  {

   SetIndexBuffer(0,myInd,INDICATOR_DATA);
   PlotIndexSetDouble(0,PLOT_EMPTY_VALUE,EMPTY_VALUE);  
}

as well as and in addition to;

int OnCalculate(const int rates_total,
                const int ...

   PlotIndexSetDouble(0,PLOT_EMPTY_VALUE,EMPTY_VALUE);

for no avail.

I don't think that adding PlotIndexSetDouble(0,PLOT_EMPTY_VALUE,EMPTY_VALUE) ; to OnCalculate() is a good idea. Again, seeing the whole code would help here.
