Indicator date limits

[LorneCash]

I would like to limit an indicator to only plot from a specific date to a specific date on my chart. For example I might have 6 months of data but I want to plot an indicator on only the the first 3 months or only the last 3 months without having it show for the rest of the chart.

Let's consider an SMA I want it to calculate accurately the first day I see it to the last day I see it but to only show a value between the ranges I specify. I don't want it to start calculating on the first day but only show on the first day.

I can think of several ways I might do this but I would like some input on what you think is the best way.

In my specific indicator I am overriding the Plot method and I was thinking there might be something there that could make it easy. My Plot started with the code in the ZigZag and made a couple minor tweaks. For reference you may assume my public override void Plot is the same as the one in ZigZag.

Set the color of the plot to transparent for those days for which you do not wish to have the indicator displayed. You can do this in OnBarUpdate().

if(Time[0].Date < minDate || Time[0].Date > maxDate)
     PlotColors[0][0] = Color.Transparent;

Your indicator will now be displayed between minDate and maxDate, but not outside that range.
